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.
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.
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 The Tavor entered service in the early 2000s and has been superseded by the X95 and joined by the 7.62 chambered Tavor 7.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.
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.
