Rheinmetall G3

We’re all familiar with the Heckler & Koch G3 and its roller-delayed blowback action. What is less well-known is that H&K were one of two companies originally contracted by the West German government to produce the Bundeswehr’s new service rifle. The other company was Rheinmetall and today we’re lucky enough to be taking a look at an example of an early production Rheinmetall G3.

The rifle which became the G3 was of course originally developed by German and Spanish engineers working at the Centro de Estudios Tecnicos de Materiales Especiales (CETME) and was intended to equip the Spanish armed forces. Initially, the West German Bundesgrenzschutz (border guards) were interested in purchasing a substantial number of the new CETME rifles, with an initial order for 5,000 agreed, however, in September 1955 the order was cancelled due to delays in production and the Bundesgrenzschutz subsequently ordered the FN FAL instead.

In November 1955, the Bundeswehr (West German military) was formed and began to search for a suitable new 7.62x51mm service rifle. Having observed the Bundesgrenzschutz’ testing the fledgling Bundeswehr took an interest in the CETEME rifle. 400 ‘STG CETME’ rifles were ordered for troop trials and these were assembled in Germany by Heckler & Koch. The rifles were delivered in late 1956, and comparative trials against the FAL began the following year.

The trials found the ‘STG CETME’ to be satisfactory in terms of features and design but lacking in durability. A number of small changes were requested including a flash hider suitable for launching rifle grenades, either a flip-up or dioptre rear sight instead of a traditional tangent style, a case deflector, a simpler more ergonomic pistol grip, a longer more ergonomic cocking handle, changes to the recoil spring guide and tweaks to the shape of the buttstock. Additional improvements such as a stronger bipod, lighter magazine, a last round hold open mechanism, overall lightening of the rifle, a lighter 20-round magazine and a proper handguard were also requested.

FN were unwilling to grant Germany a manufacturing license and the $110 per rifle price for the FAL proved substantially higher than CETME’s production estimates (The ArmaLite AR-10, J. Putnam Evans (2016), p.204). With adoption looking likely, legal wrangling over patent ownership began between Mauser, Rheinmetall and Heckler & Koch. All claimed the ownership of the roller-delayed blowback principle used by the CETME rifle. Eventually, however, the West German government awarded Rheinmetall and H&K future production contracts for the new rifle with the government supporting H&K’s claims but the legal battles continued for almost a decade.

In the meantime, with production of the CETME rifle not yet initiated and in light of some durability/reliability issues suffered during the STG CETME’s troop trials, 100,000 ‘Series C’ FN FALs were ordered for the Bundeswehr in late 1956. In 1957 the Swiss SIG 510 (designated the G2) and the American ArmaLite AR-10 (designated the G4) were also evaluated. Once the modifications requested after the troops trials were completed by H&K, a run of twenty rifles was produced and tested again.

In 1959, the West German government finally adopted the CETME rifle, designating it the G3. The German federal government decided that they wished to purchase the worldwide manufacturing rights to the G3, which naturally the Spanish government was reluctant to agree to. An agreement was finally reached in January 1958 and the contract giving West Germany worldwide rights to the G3 was finalised on February 4th, 1959.

One issue was that in June 1957, CETME had agreed a licensing deal for manufacture and sale of the rifle with a with a Dutch company Nederlandsche Wapen en Munitiefabriek (NWM). In order to gain the manufacturing rights sold to NWM the German government awarded the Dutch company a lucrative contract producing 20mm ammunition (Full Circle, p.234).

Interestingly, as the German government owned the manufacturing rights, H&K initially had to pay the government 4 Deutsche Marks per rifle, despite having been awarded the contract by the German government. In late January 1959, H&K were awarded the first substantial production contract, amounting to 150,000 rifles. Rheinmetall were subsequently awarded a similar contract (Full Circle, p.235).

According to R. Blake Stevens’ book on the roller-delayed blowback action, Full Circle, Rheinmetall produced 500,000 G3s during the 1960s, delivering 8,000 rifles per month (Full Circle, p.287). As H&K had been designated as the technical lead on the G3 project, Rheinmetall’s engineers made no attempts to develop modifications or improvements and even when H&K had switched to plastic furniture the Rheinmetall guns continued to use wood. Rheinmetall’s only other G3-related project was the RH4, a 7.62x39mm chambered, roller-locked but gas-operated rifle designed for export (Historical Firearms).

In addition to the G3, Rheinmetall were the sole manufacturer of the MG3, the 7.62x51mm MG42. Blake Stevens explains that in 1969, when a new tender for G3 production was due, that H&K moved to undercut Rheinmetall who had until now held the monopoly on MG3 production (Full Circle, p.292). As a result an agreement was reached where Rheinmetall retained their monopoly on MG3 production and H&K became sole manufacturer of the G3 for the West German military.

Examining An Early Production Rheinmetall G3

The G3 went through a large number of changes both before and after it went into service. The rifle we’re examining today is a good example of an early production rifle, as adopted in 1959. This rifle is lightly marked with ‘G3 [Rheinmetall’s ‘star-in-a-circle’ logo] followed by a serial number of 745 and below that it is date marked with the ‘3/60’, for March 1960.

DSC_0043

Working our way from the muzzle back; the rifle has the early style of flash-hider/grenade launcher support which was introduced in 1957 and altered in early 1961, an enclosed front sight and a detachable bipod (which was not Bundeswehr general issue). It has a stamped metal handguard which was replaced by one with a wooden insert in 1961, before H&K introduced plastic furniture in 1964.

The folding carrying handle seen on the troop trials rifles has been removed, the receiver is stepped for the attachment of a scope base and the magazine housing has a single strengthening rib, rather than the later ‘full-frame’ continuous rib. It has an S-E-F selector (S – Sicher/safe, E – Einzelfeuer/semi, F – Feuerstoß/auto) and black plastic pistol grip. Internally, the rifle has a captive mainspring. Unlike later G3’s the rifle has a 2-position folding L-shape rear aperture sight with apertures for 200 & 300 metres rather than the later dioptre sight adopted officially in mid-1960. The rifle has a wooden stock held with a stamped metal sling attachment and a plastic buttplate.

Live Fire: Remington M1917

This week’s episode is a short video of my first trip to the range with the Remington M1917. I basically wanted to get an overall feel for the rifle and see how the zero was. It was a beautiful day, and shooting the M1917 was a lot of fun.

I did take along my proper video camera but in a profoundly rookie move, I forgot to check it had a memory card in it. So had to improvise and use my phone, the results aren’t too bad!

The only range available that afternoon for zeroing was a 100 yard range. The first increment on the M1917’s ladder sight is 200 yards, so I set my aperture a little lower and put 8 rounds of 123gr SAKO .30-06 through the rifle, just to see where point impact was.

IMG_20190420_163848.jpg

The results were better than I expected. With a six-oclock hold on the 7 ring I got a spread of about 7 inches. This was entirely due to me get used to the rifle and forgetting to bring along a rest. I was just pleased to see rounds on paper. My groups tightened up as the afternoon went on and I’m definitely looking forward to getting to the range with the M1917 again – hopefully with a memory card!

We’ll take an in-depth look at this rifle in the future, and we’ll hopefully have videos on its British predecessors too. In the meantime, bonus video here.

The 6pdr QF Anti-Tank Gun

Previously we have discussed Britain’s first anti-tank gun, the QF 2pdr. Today we’re going to examine its successor, Britain’s second anti-tank gun – the 6pdr.

Development of the gun actually began before the war in 1938, but the QF 6pdr MkII Anti-Tank gun didn’t enter full production until 1942. After the evacuation from Dunkirk in the summer of 1940, and the loss of nearly 600 AT guns, it was decided to focus on the 2pdr which was then already in production. The 6pdr saw action for the first time in the Western Desert against the Afrika Korps, serving alongside its predecessor the 2pdr.

DSC_0724

The 6pdr was a 57mm gun, firing a 57x441mmR shell effective out to 1,700 yards or 1,500m – with a rated maximum range of 5,000 yd. Unlike its predecessor the 6pdr could fire both armour piercing and high explosive rounds. The gun weighed in at 2,520 lb or just under 1,150 kg. Manned by a six man crew the gun had a vertically sliding breechblock and could fire up to 15 rounds per minute.

DSC_0732
Breech View of the QF 6pdr (Matthew Moss)

The 6pdr had a Hydro-pneumatic recuperator which mitigated some of the gun’s recoil. The barrel recoiled around 30 inches along its cradle immediately after firing. It was mounted on a variety of carriages with the most common being a split trail carriage with 45-degrees of traverse left and right. The 6pdr could be fired with its split trail deployed or closed. The gun could be elevated 15-degrees and depressed 5-degrees – less than its predecessor, although elevation was not a key requirement for a direct fire weapon like an anti-tank gun.

Five Marks of 6pdr were produced, the MkI development model was declared obsolete and didn’t enter production. Production of the MkII began in late 1941, it had a shorter barrel and was later replaced by the longer barrelled MkIV, which also had a single-baffle muzzle brake, one of the first British guns to have one. The MkIII and V variants had special lugs to enable them to be mounted in tanks. The first guns produced were MkIIIs, while these could be carriage mounted they were earmarked for tanks.

The MkIII Airborne carriage was designed to be lighter so it could be transported aboard gliders and aircraft. Its trail legs were jointed in order to save room and the carriage was narrower which restricted the traverse to 37-degrees left or right. The shield was also redesigned with an even smaller profile. Identifiable by its straight, rather than wavy, top edge.

The gun was aimed using a No.22C 2 or 3-power sighting telescope, located on the left side of the gun, which projected through a sight box in the shield. The gunner also had an elevation wheel to his right and, unlike the 2pdr, the 6pdr used a free traverse rather than a geared wheel system. This was controlled by the gunner pushing or pulling the gun. The gun was fired by a firing lever on the left side of the breech. On the right side of the gun, an ammunition box with space for three rounds could be attached to the shield for emergency use. The gun shield consisted of two/four sections, made of bulletproof steel plate, which had a lower profile than the earlier 2pdr.

Unlike the 2pdr, the 6pdr had an array of ammunition that continued to evolve during the war. The initial armour piercing round could penetrate 70mm or 2.8in of armour at 1,600 yards / 1,500m while the Armour-Piercing Capped Ballistic Cap (APCBC) introduced in early 1943 increased this to 3.1in, while the Armour-Piercing, Discarding Sabot (APDS) shot introduced in Spring 1944, enabled it to effectively engage Tiger I and Panther frontal armour, penetrating 4.8 inches of armour at 1,500m. It is worth noting that figures on penetration vary somewhat from source to source. A high explosive shell that allowed the guns to engage non-armoured targets more effectively was introduced in 1943.

Initially used solely by the Royal Artillery’s anti-tank regiments comprising of four batteries, each with 12 guns. By 1944 an infantry division would be equipped with as many as 78 6pdrs and more than 30 heavier 17pdrs while an armoured divisions was equipped with 30 6pdrs.

THE BRITISH ARMY IN NORTH AFRICA 1942 -iwm2

The 6pdrs first saw action in North Africa proving to be highly effective against both Italian and German armour. During the Second Battle of El Alamein, 19 6pdrs were instrumental in the defence of Outpost Snipe. The 2nd Rifle Brigade and their supporting 6pdrs managed to knock out more than 55 Axis armoured vehicles including Panzer IIIs, Semovente 75/18 self-propelled guns and a number of Panzer IVs. The gunners used enfilading fire to target weaker side armour and interlocked fields of fire caught advancing tanks in killing grounds.

During Operation Market Garden, the airborne 6pdrs of the Airlanding Anti-Tank Batteries proved critical in beating back German armoured counter attacks around Oosterbeek and at the bridge in Arnhem itself. They were instrumental in repulsing the SS reconnaissance battalion which attempted to cross the bridge on the second day of the battle.

One desperate action involving a section of two 6pdrs saw three StuG-III self-propelled guns knocked out before the crews of both guns were killed. The last survivor, Lance-Sergeant Baskeyfield managed to man on of the guns alone and destroy a fourth StuG-III before he was killed. For his actions he was awarded the Victoria Cross.

Like its predecessor the 6pdr was also used as a vehicle gun, mounted in the Churchill Mks III & IV, Valentine Mk IX and the Crusader Mk III tanks as well as the Canadian MkII Ram and the MkII AEC Armoured Car. These vehicles had previously been designed to mount the 2pdr, but were adapted to fit the new 6pdr, in some cases having to remove a crew member from the turret to make enough room to fit the new gun. The Cavalier, Cromwell and Centaur tanks were designed to mount the new larger gun from scratch.

The first tank, equipped with a 6pdr, to go into action was the Mk III Churchill, which took part in the disastrous Dieppe Raid in August 1942. The new tanks, assigned to the 14th Army Tank Regiment (The Calgary Regiment (Tank)), were all abandoned or destroyed during the raid.

In North Africa, like the 2pdr, the heavier guns were mounted on trucks as Portees. Additionally AEC produced the Mk1 Gun Carrier or Deacon self-propelled gun – a 6pdr mounted in an armoured turret on the back of an AEC Matador truck chassis. These performed well in the desert but more enclosed country made them vulnerable and they were removed from service after the North African campaign.

It was not only tanks the 6pdr found itself mounted in. Coupled with the Molins automatic loading system it was also mounted in the RAF’s De Havilland Mosquito Mark XVIII ‘Tstetse’ and the Royal Navy’s motor torpedo boats. The Navy’s Molins auto-loader allowed the gun to fire a 6-round burst at a rate of 1 round per second. Nearly 600 naval versions of the gun, the QF 6pdr MkIIA, were produced. The RAF’s use was more short-lived with only 17 6pdr Tstetses built before 3in rockets were standardised. Despite this two Tsetse of 248 Squadron sank the German submarine U-976 in March 1944.

The US also adopted the 6pdr to replace their 37mm M3 anti-tank gun. It had initially been planned to produce the 6pdr in the US under the lend-lease agreement (4,242 guns were eventually delivered for British use) but in May 1941 the US approved the production of the 6pdr as the 57mm M1 Gun. The US M1 guns had a longer barrel than their British counterparts and many smaller differences in manufacture. The US, like Britain, mounted the gun on vehicles such as the M3 half-track – the T48 Gun Motor Carriage. By the end of the war the US has produced over 15,600 M1 anti-tank guns.

Ordnance QF 75mm was developed from the 6pdr, the 75mm guns were manufacture by boring out the 6pdr’s barrel to enable it to fire the US 75mm M46 HE round. The QF 75mm was fitted to a number of British armoured vehicles from 1943 onwards.

The 6pdr was a simpler gun to manufacture than its predecessor but despite being effective throughout the war it too was surpassed by a heavier gun, the QF 17pdr AT gun, which was developed in the early 1940s, the 17pdr was accepted for service in May 1942 but the 6pdr remained in service alongside the heavier guns.

After the end of the war the 6pdr continued to see use with a number of countries including Israel during the 1950s, the Irish Army and South Korea during the Korean War. The 6pdr remained in British service until 1951, before being replaced entirely by the 17pdr.

Ford M1918 Light Tank- America’s First Tank

When the US entered World War One in April 1917, the US Army had no experience with tanks. American observers in France had reported on the early Allied uses of tanks at the Somme and American enthusiasm for the new machines was lacking in many of the Army’s upper echelons.

This began to change after the arrival of General Pershing and his staff in France, ahead of the American Expeditionary Force. Pershing directed that a Tank Corps be raised and detailed a number of officers, including the enterprising young officer, Captain George S. Patton, to establish a training ground and report on how best to deploy tanks.
Patton was instrumental in shaping the US Army’s early tank doctrine, he wrote a highly detailed report on how to deploy tanks to maximum effect. Patton, a cavalry officer by training, admired the French Renault FT’s speed, mobility and manoeuvrability but felt the two doctrines of French light and British Heavy tanks could be combined. In December 1917, Colonel Samuel Rockenbach was placed in command of the new, but still tank-less, US Tank Corps.

Britain and France shared their tank designs with the US but in early 1918, the American automobile giant, Ford, began work on an American light tank. The result was a light and mobile tank weighing in at 3 US tons (or 2.7 metric tons). Sometimes referred to as the Ford 3-Ton Tank or the Ford Model 1918. Ford hoped to produce the new tank using as many off the shelf components, from their automobile and truck production, as they could. So the new tank was powered by two 4-cylinder Ford Model T engines, in theory developing around 40 horsepower, with a maximum speed of 8 mph and an operational range of just over 30 miles. Taking cues from the French FT, the M1918’s engines, fuel tank and transmission were mounted in a compartment at the rear of the tank. Some sources note that the tank was developed with the assistance of the Van Dorn Iron Works, in Cleveland, Ohio, presumably assisting in the manufacture of bullet-proof steel plates making up the tank’s armour.

An early version of the 3-Ton Ford being assembled in one of Ford’s Detroit workshops (US National Archive)

Contemporary photographs show the prototype during assembly in one of Ford’s Detroit workshops. We’re extremely lucky to have these photos showing the development process, they show that the initial shape and layout changed very little but some important changes were made as the tank was tested. The photographs date to April 1918, suggesting that by late spring the first prototype was assembled.

Like the French FT, the M1918 had a two-man crew but was significantly lighter weighing 4 tons less. The Ford could reach speeds of up to 8 mph while the slower FT could achieve around 5 mph. The Ford M1918 was 14 feet (or 4.3m) long, making it slightly shorter than the FT. The Ford’s armour was much thinner than its French counterpart, while this helped with weight, it would have left the crew vulnerable. It had just 7 to 13mm of armour compared to the FT’s 8 to 22mm. The tank’s tracks were also extremely narrow, and while the tank was light, this could have conceivably led to issues with getting bogged down in thick mud. Some of the contemporary footage of the prototype shows it with wider, more practical looking, tracks but the later pre-production models seem to have reverted to the narrower tracks.

165-WW-303A-116 - Copy

The earlier prototype Ford tank did not have a gun fitted and the front doors for both driver and gunner were hinged at the sides, rather than at the top. Some of the contemporary footage shows the gun-less prototype becoming trapped nose-up, at an almost 90-degree angle, after trying to cross a relatively narrow trench. To prevent this we see that the later tanks were subsequently fitted with a ‘trench tail’.

In terms of armament, the Ford was also limited with a single .30 calibre machine gun, mounted on the right side of the hull in an armoured casement. The casement doesn’t appear to have a prominent sight aperture or vision slit for the driver so how the gun was aimed is unclear. The gun also appears to have a very limited firing arc compared to the FT’s turret mounted gun, which could rotate a full 360 degrees. It is unclear exactly what sort of gun was going to be mounted in the tank although an Hotchkiss M1909 Benét–Mercié (also used in British tanks) may have been an option. Another more likely option would have been the specially-developed M1919 air-cooled Browning Machine Gun, which had been specially developed for tank mounting. Judging from the size of the armoured housing for the gun, however, it may have been intended to mount the M1918 Marlin Tank Machine Gun, which had large aluminium cooling fins.

If we look closely we can see that the gunners hatch appears to be hinged, suggesting it can be opened too. Just to the right of the gun there is a round hole in the armour with what appears to be a starting handle sticking out of it (US National Archive)

The Ford had a two-man crew with the driver on the left and a gunner on the right. The driver also had a cupola, with vision slits, on the roof of the tank which allowed him to drive when the hatch was closed. But this must have been difficult to see out of unless the driver changed his driving position.

The tank had an exposed front axle connecting its large front track idlers, this would have been susceptible to damage from enemy fire and from hitting obstacles. At the rear is the drive sprocket and along the body of the tank are two sets of three suspension wheels with two track support rollers above. Note that the support rollers are mounted on a truck leaf spring, another example of off-the-shelf parts being utilised. This represents a change from the single support roller seen in the earlier prototype

The later footage shows as many as half a dozen pre-production tanks on the move during a demonstration at Ford’s plant in Detroit. We get a good feel for how fast and manoeuvrable the Ford tanks were. But they also struggle to navigate some of the more difficult terrain and don’t appear to have the power or traction to tackle some of the steeper hills or ditches. The tanks much have been difficult to steer, likely using a pair of clutch levers to control the tracks on either side. Two tanks even collide with each other and there’s a couple of other near misses as the Ford’s navigate around the test area. One tank becomes stuck requiring two others to pull it clear of the bank.

Six pre-production Ford M1918s lined up before a demonstration (US National Archive)

The War Department was eager to get tanks into production ordering 15,000 M1918s from Ford, with 500 to be delivered in January 1919 with production continuing at 100 per day after that. An initial batch of 15 were ordered for testing. At least one of these was sent to France for evaluation before the end of the war. The French were unimpressed finding it inferior to the FT, they did consider it as an artillery tractor for the French 75. The US also considered the Ford for this role and some photograph captions from early 1919, of Battery A, 140th Field Artillery, describes it as a ‘3-ton tractor’ for pulling “the new American 75mm split trail gun”, the M1916. These photographs also prove that more than one M1918 reached France.

The Ford tanks were not well regarded by those with practical experience, with the men of the US Tank Corps in France not consulted about the tank before it was ordered by the Ordnance Department. The war ended before large scale production of the M1918 could begin, With just 15 M1918s built we’re lucky to have this much film of it in action. Today only two of the Ford light tanks survive in US Army collections.

In reality the M1918 was more a Machine Gun Carrier than a tank. How effective it might have been is a matter of speculation. It’s difficult to say, while the French may not have felt it was an improvement over the FT, it certainly showed enough merit for the War Department to make a large order. Its narrow tracks, lack of protection and minimal armament may have proved to be problems. The M1918’s real legacy is that it while the US had built other tanks during the war, including the M1917, a copy of the FT, and the MKVIII heavy tank, in collaboration with the British, the M1918 Ford was the first truly American designed and built tank.

The Galil ARM & its Inventor

Galil Development

The Galil rifle adopted by the Israeli Defence Force in 1972 was designed by Yisrael Galili and Ephraim Yaari of IMI following the disappointing performance of the FAL in service with the IDF since the early 1950’s. These failings of the FAL in service were mainly due to the poor reliability of the FAL with some of the mainly conscript troops in the field mainly down to poor maintenance and cleaning by the users in the field. The Israeli military found that captured AK47 rifles functioned more reliably without the routine maintenance that the FAL required, this was down to the finer tolerances and mechanism that the FAL employed whereas the AK47 could function reliably without the same level of cleaning and maintenance.

In the late 1960’s the IDF carried out a series of trials to select a replacement for the FAL. As part of those trials the following small arms were tested:

  • M16A1
  • Stoner 63
  • Heckler & Koch HK33
  • AKM
  • Armalite AR18
  • and a pre-production rifle from Beretta that ultimately led to the AR70 series rifle.

The result was that the AKM rifle came out as the winner of the trials but with some reservations. The Israelis didn’t like the stamped receiver of the AKM and as part of the trials they tested the Finnish M62 AKM variant rifle which had a machined receiver built from a steel billet which made it much more robust but heavy. This became the basis of what was to become the Galil.

A cold hammer forged barrel was selected together with a unitised front sight/gas block with a front sight base adjustable for elevation and drift adjustable for zeroing. The rear sight was positioned at the rear of the dust cover, which itself was strengthened to be more rigid than a standard AKM and allow the rear sight to maintain zero. The rear sight was an ‘L’ shaped flip type with positions for 300 & 500 meters. Flip up night sights were also fitted, they came with Tritium inserts. The folding stock was a virtual copy of the FN FAL Para type.

I won’t cover the Galil in any more detail as it has been covered by several others in great detail, what I will detail in future videos and articles is my own experiences of the semi-automatic ‘Sporter’ Galil rifles as well as the other IMI products that I have extensive knowledge of.

Meeting Yisreal Galili

Back in the early 1980’s IMI had been courted by several US companies to develop semiautomatic ‘clones’ of their military small arms. Action Arms worked with IMI and the UZI Carbine was developed primarily for US civilian sales by them from 1980. Following on from the UZI Carbine, semiautomatic versions of the Mini UZI and then the UZI Pistol were developed and sold.

Magnum Research Inc. as part of their partnership with IMI in developing the Desert Eagle pistol also marketed the semiautomatic versions of the Galil rifle in the USA.

In the UK at that time I was working part time as the armourer and technical advisor for the UK & Commonwealth distributor of IMI products Pat Walker Guns. I had worked with Pat since 1980 refurbishing and converting select fire and fully automatic ‘surplus’ small arms to semi-automatic only ‘civilian’ legal configuration for sale on the UK & Commonwealth collector/shooter market. This was a wonderful job as I got to travel a lot to see caches of surplus small arms and work on them… halcyon days!

In or around 1983, Pat acquired the IMI agency for the UK, and as part of that agreement we had to be trained on IMI products so we could service and support them as the distributor. In October 1984, we flew to Tel Aviv in Israel to attend the first (and possibly only) armourers course on the entire family of IMI small arms! The UK team consisted of myself, as the technical part of the team, Pat Walker as the UK agent/distributor, and Colin Greenwood who was the editor of the very popular UK shooting magazine GUNS REVIEW who was attending the course so as to write an article for said magazine.

Once we arrived in Israel we were accommodated in the Plaza Hotel on the beachfront in Tel Aviv. That evening we were introduced to the other attendees on the course who came from the USA, Germany, Italy, the Netherlands, Switzerland, Finland, and a South American country… We were introduced to some of the IMI personnel, which included Yisrael Galili, and given a rundown of the schedule for the next week.

During our time on the course we were given several ‘live fire’ demonstrations by none other than Yisrael Galili himself as well as Efrahiem Yaari (who would later go on to head up the special operations and weapons division of IMI as director in later years). We also got to handle and shoot all of the small arms IMI manufactured at that time including select fire versions and some prototype Desert Eagle pistols. In the evenings we were shown and also had to demonstrate how to strip, assemble, and troubleshoot all the IMI guns we had shot earlier that day… it became a source of entertainment that myself and the armourer of the Dutch distributor would see who could strip and reassemble each gun type the quickest… I won many a beer in those contests!

During one of the sessions where we were taught to strip the Galil, Yisrael Galili handed out some photocopies of a now infamous photo of the specially adapted Galil. He told us it was a special Galil for ‘mature’ IDF girls. Our friend Miles has a good article about the ‘Female Galil’ here.

We were given guided tours of the IMI manufacturing facilities seeing how each model and each family of small arms were machined and assembled. We also got to visit the IMI ammunition plant and saw manufacture there as well as test firing the civilian brand of SAMSON ammunition they manufactured.

It was with great pride that on the last evening we were in Israel we were each presented our armourers certificates and a commemorative book on the history of Israel by the Director of Sales Yehuda Amon at a presentation dinner in a restaurant in the ancient town of Caesarea. I also got to thank personally Mr Galili and Mr Yaarifor their excellent tuition and fantastic displays of weapons handling.

It was a fantastic opportunity for a then young man of 23 to get to work with such an influential smallarms company as IMI and get to meet such notable designers as Ysrael Galili and Ephraim Yaari. Sadly, the passage of time has robbed us of many of the people I shared that experience with Pat, Colin, and Mr Galili are sadly no longer with us. Luckily a few of those I met on the course are, and I still corresponded with them to this day.

Watch out for future articles and videos on my personal experiences with small arms.

Live Fire: Bren Mk1 (Modified)

Introduce in British service in 1938, the Bren remained in use into the 1990s. Based upon the Czechoslovakian series of ZB light machine guns, its name comes from an amalgamation of its origins: BR for Brno, the factory in Czechoslovakia, and EN for RSAF Enfield where it had been adapted for British service and was to be produced.

The Bren is chambered in .303, is gas operated and fires from an open bolt. It feeds from a top-mounted 30 round box magazine, as such the sights are offset to the left meaning the Bren can only be fired from the right shoulder – which as a lefty, I quickly realised.

Bren Mk1(Modified) (Matthew Moss)

This example does not have the scope mounting dovetail machined into the left side of its receiver, or the folding grip and the hinged shoulder rest indicating that it is a Mk1 (Modified) ‘Pattern A’ gun, which was introduced after the evacuation of Dunkirk, the British Expeditionary Force lost most of the 30,000 Brens that had been taken to France. Only around 2,000 remained in inventory in the summer of 1940, so increasing production was essential, this model and the even more simplified MkII were introduced. While at the same time the BESAL light machine gun was developed as an emergency alternative by BSA – check out our earlier video on the BESAL here.

As a Mk1, the gun has the original profile buttstock, with the fitting for a rear folding grip and tripod attachment point as well as a buttcap. It also has the drum rear sight rather than the later ladder sight of the Mk2 & 3. It also had a folding cocking handle and this Mk1(M) gun also has the earlier pattern height adjustable, rather than fixed, bipod legs. This gun is marked ‘MK1, with an E within a D, 1942’ indicating it was made at RSAF Enfield.

The Bren’s relatively slow rate of fire (of around 500 rounds per minute) makes it controllable and very easy to fire single shots while in full auto. The Bren does, however, have a selector on the left side of the gun, just above the trigger guard, which can be set to safe, semi or fully automatic. The Bren has a rocking recoil impulse as its heavy bolt moves back and forth, easily manageable if held tightly into the shoulder with the off-hand holding onto the wrist of the stock. The top-mounted magazine when fully loaded does have a tendency to want to fall to the side but once you’re used to this it’s not really an issue. The legend surrounding the accuracy of the Bren is certainly somewhat valid, at the time it was recognised as an accurate weapon and I found it accurate from my short time behind the trigger.  I found the Mk1’s rear sight aperture and drum adjustment easy to use.

Spent cases eject out of the bottom of the receiver, the weapon had a sliding dust cover for when the magazine was removed and the charging handle is non reciprocating and folds forward.

The Bren has a quick change barrel system. To remove the barrel the release catch in front of the magazine was rotated upwards to unlock and then the barrel was rotated 90 degrees clockwise by bringing the carrying handle up to the 12 o’clock position and then sliding it forward.

We’ll have a more in-depth look at the Bren and its Czech predecessors in the future. My thanks to my friend Chuck over at Gunlab for letting me put some rounds through his Bren, I got a real kick out of it!

Heckler & Koch HK33

Heckler & Koch’s first 5.56×45 rifle, the HK33, was introduced in the late 1960s as a response to the emergence of the new 5.56x45mm round and the introduction of the FN CAL. The HK33 is little more than a scaled down version of HK’s successful 7.62×51 G3. Developed by Tilo Möller, the HK33 used the same roller delayed blowback action and shares most of the G3’s features.

Left & right views of the HK33 (Matthew Moss)

It has a stamped receiver and uses the same plastic furniture and pistol grip/trigger mechanism housing as the G3. The rifle is 39 inches or 92cm long and is by no means a light weapon, weighing around 4kg or 8.7 lbs. The HK33 feeds from 25, 30 or 40 round proprietary HK magazines.

The rifle came in main two main variants a full length version with a fixed stock, which could be fitted with a collapsing stock, and a shortened K-variant with a shorter barrel. The weapon came with either a safe, semi and full auto or safe, semi, 3-round burst fire control mechanism.

The HK33 was not adopted by the West German Army, however, it did see extensive use with Germany’s federal state and police forces and the Bundeswehr special forces. While it wasn’t adopted at home it was a successful export weapon with dozens of countries purchasing and adopting the rifle. France tested the improved HK33F in the Army 1970s and although it performed well the FAMAS was adopted instead. A production license was sold to Thailand who adopted the HK33, purchasing 40,000 rifles and the license to manufacture 30,000 more. Thailand also developed their own unique bull pup version of the rifle, the Type 11.

Malaysia also purchased 55,000 HK33s and the Spanish Guardia Civil used them for a time. The manufacturing rights for the HK33 were also sold to Portugal for production at Fabrica Militar de Prata and to Turkey where it remains in production at MKEK.

A comparison of the HK33’s bolt with the later HK G41 (Matthew Moss)

HK produced the HK33 from 1968 through to the late 1980s. It also provided the basis for the HK53 5.56 ‘submachine gun’ which we have covered previously. It was also the basis of the less successful G41, which we’ve also covered in a full length episode, you can find this here. The similarities with the HK33 are easy to see but the G41 has a number of subtle changes.
