We’ve looked at a few cutaways in the past, today we’re going to take a look at a Lee-Enfield Rifle No.4 cutaway.
One of the main drawbacks of the venerable SMLE was that it was expensive and time consuming to manufacture. The No.4 was an attempt to address this. It evolved from the experimental No.1 MkV and MkVI which were trialled in the early 1920s. The key mechanical change was that the barrel was free-floated and had a heavier profile to deal with expansion of the stock. The No.4 also had a new rear aperture sight mounted further back on the receiver giving a better sight picture and a longer sight radius.
With this cutaway we get a look inside the butt trap, which has a pull-through and oil bottle inside, then as we move to the action we get a look at the rifle’s trigger, sear, sear spring and magazine catch. If we look closely we can see the bolt head catch. The magazine has also been cutaway, with the magazine follower spring just visible.
This cutaway rifle has had all of the wood around its receiver removed, so we can see the magazine housing floor plate and the point where the retaining screw attaches to the trunnion. As we move along we get a look inside the chamber where the outline of the cartridge neck is easy to see and we can also see the barrel’s rifling too.
Down near the muzzle the rifle’s upper retaining band and the hand guard have been cutaway to show the barrel inside. The No.4 was adopted for service officially in November 1939 and just over 4 million were made during WW2. We’ll have a full, more in-depth video on the No.4 in the future.
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.
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!
Today’s episode is the last video of 2018, so we thought we’d end the year with a bang, literally. Earlier this year Matt had the chance to get behind an original Browning M1919A4 so we’ve put together a video showing the classic belt-fed machine gun in action with some slow motion footage thrown in!
This M1919A4 was built in 1944 at GM’s Saginaw Steering Division plant, in Saginaw Michigan. It was one of nearly half a million M1919A4s built during World War Two. In the video Matt explains a little of the gun’s history and how it worked.
This M1919 has been rechambered from the original .30-06 to 7.62x51mm NATO and uses M13 disintegrating links rather than a cloth belt or M1 disintegrating links. My thanks to Chuck and his buddy over at GunLab for letting me put several belts through his gun, it was a lot of fun.
We’ll have a full, in-depth, episode on the Browning M1919 in the future.
