CIS SAR-80

The SAR-80’s story begins in the early 1970s, when Frank Waters, the Sterling Armaments Company’s chief designer, began developing a 5.56x45mm rifle for sale to foreign militaries. While two initial prototypes were produced the project lapsed when Sterling secured a license to manufacture Eugene Stoner’s AR-18.

In the late 70s the project was resurrected and in February 1977, two prototypes were sent to Chartered Industries of Singapore (CIS)[later known as ST Kinetics] who had been seeking a 5.56x45mm rifle design to produce for export to sustain production at their factory. The initial prototypes reportedly suffered issues with obturation with some cartridges and Sterling engineers worked to rectify this with another batch of half a dozen prototypes being sent to CIS in late 1977. CIS produced their first pre-production prototypes in 1978, for testing by the Singapore Army. CIS opted for a plastic buttstock and redesigned the handguards too.

Initially described as the Sterling Light Automatic Rifle and later the Sterling Combat Rifle the rifle, however, as it finally entered production in 1979, it became known as the Singapore Assault Rifle 80 or the SAR-80. The first SAR-80s were delivered to the Singapore Armed Forces in early 1981 for troop trials. Faults with these early production rifles included poor fit and finish and extractors which bent leading to extraction and ejection issues. Refinements made rectified these faults and subsequent production runs had improved reliability.

The SAR-80 can be described as a clone of the Armalite AR-18 with their internal designs almost identical. The SAR-80 is gas-operated, with a short-stroke gas piston and a rotating bolt. The bolt has 7 locking lugs, the internal mechanics of the rifle are more or less identical to that of the AR-18, using dual recoil springs and a rectangular bolt carrier. The bolt geometries differ slightly to the AR-18’s and the SAR-80 also has an additional weight inside its bolt – which adds mass and helps slow the rate of fire down to around 600rpm. Like the AR-18 its charging handle is attached directly to the bolt carrier and is reciprocating.

The rifle feeds from standard STANAG magazines and is select-fire, with a selector on the left side of the rifle and a magazine release on the right. The selector layout is modelled after the M16’s and the front handguard’s design was also influenced by the M16. The SAR-80 has simple stamped receiver, similar in profile to the AR-18’s, it has a crackle-paint finish, like that seen on the commercial Sterling Mk4 SMGs. It has a two-position folding rear peep sight and is 97cm (38in) long and weighs 3.7 kg (8.2 lb) unloaded.

The SAR-80 had a bayonet lug just beneath its adjustable gas block and mounted an M16-pattern bayonet, other accessories included a scope mount, bipod and a blank-firing adaptor. And of course a folding stock variant was also available.

I didn’t have a chance to strip the rifle but here you can see the hammer inside the receiver – its worth noting that this rifle does not have the sliding dust cover seen on other examples, and the charging handle slot is completely open.

Developed with cost in mind, contemporary literature from CIS state an export price of around $300 per rifle, the equivalent to day of about $930. CIS produced more than 80,000 between 1980 and 1988, it saw limited service with Singapore’s military but did enjoy some export sales, with the SAR-80 used by the Central African Republic’s Gendarmerie, the Croatian Army, the Papua New Guinea Defence Force and the Slovenian Territorial Army. CIS replaced the SAR-80 with the SR-88, a rifle co-developed with Sterling as the SAR-87, but this proved unsuccessful and has since been superseded by the SAR-21 bullpup.

Cutaway Tavor

Last week Matt attended SHOT Show 2020 and spotted a pair of Tavor cutaway demonstration guns at the IWI booth. Above is a quick video, put together on the fly, looking at the cutaway guns and showing how they illustrate the Tavor’s working parts and operation.

DSC_0353
Cutaway IWI Tavor (Matthew Moss)

Developed in the mid-1990s to meet IDF requirements for a reliable and compact rifle to replace the M16s & M4s in service. The rifle had to be shorter to deal with the close quarter urban fighting the IDF often found itself in.

The Tavor or TAR-21 uses a long strike gas piston system inspired by the AK and has a rotating bolt. The bullpup configuration gave the desired compact weapon without sacrificing barrel length.

The cutaway rifles on display at the IWI booth were actually civilian, semi-auto only, Tavor SARs but they give us a good look at the rifle’s internals and how the Tavor functions. We can see the gas piston system, the charging rod and the barrel at the bottom. Moving back we can see the chamber, the bolt carrier group, the sear assembly and the bolt hold open mechanism.

DSC_0354
In this photo we can see the cutaway magazine as well as the mainspring at the top of the photo and below it the bolt carrier group and the bolt release mechanism (Matthew Moss)

They also cutaway the magazine so we can see the spring inside. At the top of the weapon we can see the mainspring that stretches back into the butt. The model was fully functional so on pulling the trigger the connecting rod acted on the sear release to trip the firing pin.

Additionally, the bolt release, just behind the magazine, also functioned and when operated the bolt went forward onto battery. The Tavor entered service in the early 2000s and has been superseded by the X95 and joined by the 7.62 chambered Tavor 7.

We will have a more in-depth video on the Tavor in the future.

Nock Volley Gun

Commonly referred to as Nock Guns, the seven barrel volley guns were actually designed by James Wilson. Wilson presented his design to the Board of Ordnance for testing in July 1779. Following testing at Woolwich Arsenal the Board of Ordnance decided that the guns, while of no use to the Army, might be useful aboard the Royal Navy’s ships. The volley gun’s impressive firepower could be devastating at the relatively short ranges aboard ships. The Navy had historically used blunderbusses/musketoons and the Board of Ordnance probably viewed Wilson’s gun as an advancement of this concept. London gunmaker Henry Nock was given an order for two ‘seven barrelled rifle guns’ for Admiralty testing but these proved slow to load in action and subsequent guns had smoothbore barrels.

DSC_0262a

The Admiralty envisioned equipping first rate ships of the line (vessels with 75 guns or more) with 20 volley guns, while second and third rates would have 16 and 12 volley guns respectively, and frigates would carry 10 Nock guns. This represented a sizeable order. The Admiralty eventually purchased 500 guns, paying £13 per gun, to equip Royal Marines and sailors manning the fighting tops (at the top of ship’s masts). The Navy felt that the volley guns’ firepower would be useful when boarding enemy vessels or in repelling boarders by pouring down fire on enemy boarding parties.

Henry Nock, better known for producing high quality duelling pistols and sporting guns, became the sole supplier of Wilson’s volley guns to the Royal Navy. The weapon’s 0.46 inch calibre outer barrels were arranged around the seventh centre barrel. The 51cm or 20in barrels were brazed together and screwed to an iron plate set into a walnut stock. The outer barrels had vents drilled through them to the central barrel while the central barrel had a vent leading from the lock. Once the flintlock ignited the powder charge in the central barrel, the surrounding barrels were ignited through the vents. As the vents had to be drilled with the barrels already brazed into position, the outer barrels all have plugged drill holes on their outer surfaces.

DSC_0264
A close up of the lock and the ‘H. NOCK’ makers mark (Matthew Moss)

All seven barrels fired almost at once producing significant recoil, reputedly able to dislocate shoulders. The service load was originally 2.5 drams of finer rifle powder (which I believe equals 68gr) for each barrel – totalling 476gr. Despite the gun weighing 12lbs, this did little to mitigate the weapon’s recoil and a reduced charge or 1.5 drams of standard musket powder was ordered.

The Board of Ordnance and the Admiralty granted Wilson an awarded of £400 (equal to £48,000 or $63,000 today) in May 1780. He played no further role in the testing and development of the volley gun. In 1787 the Navy ordered a further 100 guns from Nock.

DSC_0267a
Left-side profile of the Nock Gun (Matthew Moss)

Entering service just too late for service during the American War of Independence the first reported use of the guns came with Admiral Howe’s fleet at the siege of Gibraltar in 1782. They continued to be carried aboard other vessels during the 1790s, but few accounts refer to them and little is known about their service.

Howard Blackmore suggests that naval officers, including Admiral Nelson who disliked placing marksmen in his tops, disliked the guns. There were some fears that the volley guns’ wads could set the ships sails and rigging on fire. Reputedly it was also not uncommon for some of the volley gun’s barrels to fail to ignite. As a result the guns were seldom used on board ships and removed from Royal Navy service in 1804. In 1805, Wilson, then a captain of the Marines suggested the Navy reissue the guns to the Sea Fencibles, a naval militia which helped defend the British coast, however, his recommendation was not followed up.

large_A3018_8
The early (top) and later (bottom) patterns of Nock volley gun (Royal Armouries)

This particular example has the second pattern of lock used on the Nock guns with a smaller lock positioned a little lower on the gun. The earlier pattern was a back action lock, fitted high on the gun with the front of the lock plate in line with the side of the barrel.

The gun has a maker’s mark of ‘H. NOCK’ on the second barrel on the left and various barrel proof marks. Unlike other examples the lock itself isn’t Tower and ‘GR’/Crown cypher marked but does have the Ordnance Broad Arrow just behind the pan. Interestingly, the steel ramrod appears to have an extension brazed onto the end of it, this might indicate that the shorter rod used with the initial charge had to be extended when less powder was used for the lighter 1.5 dram load.

Why did the Nock Volley Guns fall out of favour?

As I mentioned earlier the recoil of the initial service load was significant, Howard Blackmore hypothesised that there may have also been some weakness to the lock springs leading to misfires. One key factor is that close quarters fighting aboard ships often relied on edged weapons like cutlasses, boarding axes and pikes. These paintings give us some feel for what fighting aboard a Napoleonic Man-of-War might have been like – a close, chaotic, terrifying affair.

While pistols were commonly used they were disposable and may not have been reloaded during a fight – more likely they were dropped or used as a club. The Nock Gun would have offered a devastating first volley, and while its 20 inch barrels would have given it better accuracy and range than a musketoon, how much of an impact a single volley of seven .32 bore projectiles would have had especially once the fighting became hand to hand is a matter for debate. At close quarters the Nock Gun quickly becomes a short, ill-balanced, 12lb club.

The Nock Volley Gun is perhaps best known for appearing in the Sharpe series of books and films as Sergeant Harper’s weapon of choice but it first appears on screen in the 1960 classic The Alamo with Richard Widmark’s Jim Bowie carrying one and more recently a fleeting, anachronistic, appearance in Master & Commander: Far Side of the World.

Despite a relatively short and undistinguished service life the Nock Volley Guns also saw some civilian sales with a number of ornate hunting guns with wooden forends, engraving, rifling and rear leaf sights.

Later in 1818, Nock’s workshop manufactured a design by Artemus Wheeler, an American gun designer with a fondness for revolving guns.

Wheeler’s carbine resembles the earlier volley gun externally but is in fact a manually rotated, self-priming flintlock ‘pepperbox gun’ with six barrels arranged around a central axis. Unlike the earlier volley gun the pepperbox carbine was never trailed or purchased by the Admiralty. Henry Nock’s workshops produced approximately 655 volley guns between 1780 and 1788. The Nock Gun is a weapon that would greatly benefit from some in-depth contemporary research as the current best source is over 50 years old and relatively little is known about the gun’s service history.
