Sten Mk5: Folding stock experimental model

On a Facebook group a few months ago, someone shared a picture of something I had never seen before. As time has gone by, it has become rare for this to happen to me in the world of firearms.

Yes, that is a Sten Mk5. Yes he is shooting it around a corner using a folding stock.

Although it’s not really practical for airsoft, where shooting without looking (blind fire) is a banned practice, it was such a distinctive and interesting idea it had to happen. This is what a Cornershot carbine looks like in the late 1940s.

At first glance, it looks like a standard Sten Mk5. I turned down the barrel to make it slimmer and more shaped like the original.

From the side, you can see the slightly longer joint for the buttstock.

The wood pattern is pretty much identical.

The swivel function is controlled with the silver button. This is depressed, the stock is swivelled 90º one way or another and the spring-loaded button locks into place. At the same time, the foregrip is loosened with the thumbscrew, moved into place and tightened down. This is one area where I have deviated from the original which used a hex nut: carrying a spanner around in the field wouldn’t be practical.

You will notice that there is no prism sight on this. I looked into getting a pentaprism as used by the original, but the cost would have nigh-on tripled the price of the build.

To round off: a couple of views of it folded different ways.

 

So far as I can tell these were never properly trialled beyond the one prototype. I imagine that managing recoil and maintaining a sight picture would have been tricky, the prism would have been expensive and limited the soldier’s field of view.

If any reader has any information on these carbines, better quality original photos or recognises the magazine the snippets above have been taken from I would be very much obliged if you would get in touch on the email below.

Australian SMLE Carbine VSR

When I saw this pattern of experimental SMLE on Forgotten Weapons (see the video here) I knew I just had to make one. I used this as an opportunity to try out some of my new techniques for SMLE builds.

This carbine was conceived as a way to make the SMLE shorter and lighter, the project being run in parallel with similar programmes in Ishapore (India) and Enfield (GB), the latter of which used the No.4 as the starting point and resulted in the No.5 MkI.

This is an impression of the first shortened Australian pattern. In time I hope to replicate quite a few of the others.

It is, in essence, just a short SMLE. The only real effort to make the rifle lighter at this stage was in shortening the barrel and woodwork.

This does however make for a very handy rifle!

This was one of my first rifles to use my rubber cast buttplates. The originals used metal plates, I use rubber simply because metal plates are very hard to get presently.

Possibly the best feature of this conversion is the use of this rear-mounted aperture sight. On the original rifle, this had two settings for range, on mine I have gone for a simple zeroing elevation adjustment. 

Having used this rifle in-game I can say confidently that this is an excellent sight, far superior to a regular SMLE notch. The narrower aperture is in my opinion better than the No.4 sight, at least in daylight.

As with the original, I have put a large draft on the front of the aperture to gather the maximum light possible.

As with my other Enfield builds, I have used my custom Enfield trigger.

 

I got to use this in-game in October. The shorter, lighter version of the SMLE make this extremely handy on its own, add in the rear aperture and it’s extremely quick to bring to bear as well. As an airsoft version, I can’t comment on how comfortable it would be to shoot the original, but I suspect it would be rather brutal on recoil and have a rather blinding flash.

Although this was never adopted, I’m glad to have made my own version and can confirm it is going to a very good home.

Sten MkIV: Build

The first major hurdle for me was that my Sten was missing the massive chunk of aluminium that houses the barrel and hop up unit. I measured up one from another gun and created a 3D model to be printed. I added a section to the front for the flash hider which is a separate piece. Running through this and the other part is some 16mm steel tube for strength.

The stock is made from pieces of laser cut steel. For the very sharp bends I made cuts with the angle grinder, made the folds and welded them up.

The locking bar is kept in place with two screws. These ride in slots that stop it from travelling too far back or forwards.

The pistol grip slotted into place, welded on the bottom which was then ground flat to allow the stock to pivot. The trigger guard is huge, the bend was made with wooden formers and the shape was checked against my paper template.

A close-up of the locking system. This is a pretty solid system, with only the wobble you would expect from a typical Sten stock.

Once the stock unit was welded onto the backplate, this really started to take shape. Shown below with the stock stowed.

And the stock deployed. So far it’s more comfortable than it looks, the next step is to make the wooden grips.

These are made from some leftover walnut I had sitting around. I printed a paper template, cut them out and drilled the screw holes. Then fine fitting and shaping was done with files and the electric hand sander.

Then it was time to strip everything and finish her up.

The grips got a quick soaking with some dark red woodstain, followed by hardwax oil.

All that’s left now is reassembly, fitting a foresight and doing some internal work on the Sten. I’ve swapped the barrel out already for a shorter one but the trigger needs some TLC.

Sten MkIV: Introduction

The Sten MkIV has very little written on it, so this introduction will be rather short.

It was an experimental design to make Britain’s Sub machine gun more compact. This has several possible reasons, but the most likely seeming to my eye (lacking access to original documents) is the Airborne theory. A more compact sub-machine gun than the standard Sten MkII and MkII would make sense for airborne troops and this definitely meets that requirement.

This was ultimately met by the Mk5, which could have its buttstock removed and replaced with a blank backplate.

There were two versions of the MkIV, the ‘A’ which had a hand guard style trigger guard (some say to accommodate arctic mittens) and the ‘B’ which has the trigger and pistol grip advanced to halfway down the receiver. This was apparently an improvement but not enough it would seem!

The reason the MkIV was rejected during trials was that it was ‘uncomfortable to fire’. This does seem a little bit ironic seeing it was designed to replace the ergonomics-violating MkII and MkIIIs, but judging by what was eventually adopted the general effort was towards a significantly better gun comfort wise rather than a slight improvement.

 

The other possibility is that, being much smaller in the body than a ‘normal’ Sten (especially in the barrel) the recoil, muzzle blast or ejection may have been pretty bad. It’s pretty much impossible to say without access to trials reports or getting to fire the (so far as I can tell) only remaining piece at the Royal Armouries. I suspect it will grow legs and walk out before I am allowed to do that however!

I’ll be making a MkIVa replica based on the example in the Royal Armouries, as a bit of  change of scene from the bolt actions and machine guns I’ve been building a lot lately!

Sten MkIV: Complete

The completed Sten MkIV. Perhaps not a looker, but definitely one of the most practical SMGs I have built to date. When folded, this easily fits in a backpack making it a much more portable choice than my usual long rifles.

The large trigger guard makes it ideal for use with gloves in cold conditions.

The buttstock when folded also makes a handy foregrip. In CQB this is very practical for when poking round corners.

When  you want a little more shooting precision, just grab the inner tongue and pull it towards the buttstock.

You can then unfold the stock and lock it into position at the back.

This is pretty comfortable in this layout, though I am not sure if recoil would be easy to control. I can see how the flat steel would be uncomfortable for prolonged periods of shooting, but no more so than many of the previous models of Sten gun. Frankly compared to the prolific T-stock this would still be a huge improvement so I don’t understand how this was rejected due to being uncomfortable while shooting.

Mad Mondays: 6. The Revolver is born

As discussed a few weeks ago, metal cartridges were not an option yet as precision mass-production didn’t exist. While you could make a handful of cartridges that would work in one given firearm, Making hundreds of thousands of cartridges that would work in every musket issued to your soldiers potentially all the way around the world was a manufacturing impossibility.

During the years of the Lorenzoni action, soldiers were almost universally issued paper cartridges to speed up reloading over manual powder pouring and ball loading. As a result, well-trained soldiers could fire three to five rounds per minute with a consistent load each time. As the advantage of breech loaders became clear, militaries looked at the various options for cartridges that could be loaded from the back of the gun and continue to speed up the rate of fire.

Although manufacturing had come a long way since Henry VIII’s carbine, a universal metal cartridge wasn’t a realistic possibility yet, however if designers could find a way to make a series of cartridges that were somehow locked to the gun…

This is how the revolver was born. Early revolvers were made as rifles and pistols and in wheellock and flintlock versions, clearly developments from earlier rotating-barrel designs, some were even made by the same manufacturers.

They were quite different to the revolvers of today, cylinders were loaded from the front with loose powder, wadding and ball much like miniature musket barrels. After each shot the cylinder had to be rotated and indexed by hand. In the first models, the pan had to be re-primed as well, though self-priming pans did really start to make sense for these pieces.

This genre of firearms was short-lived, the percussion cap changed the way that firearms were able to be used and designed overnight. As a result they are not well-known today compared to their descendants of only 20 years later.

One of the few to gain any attention is the Collier system, which by modern standards was a flop with only 150-450 produced. But for hand-made, cutting edge armaments this wasn’t doing too badly for the day. This had a hand-turned cylinder and a self-priming pan, which refilled as you cocked the hammer.

Some have suggested that Samuel Colt may have been inspired to create his revolver by one of these designs, apparently coming across them during his travels in India.

However it is interesting to note that this late Collier revolving carbine in the Royal Armouries collection has either an unusually complex indexing system or something which looks awfully like a slot for a hand in the back plate and arms on the back of the cylinder…

This guy got SO close to completely revolutionising firearms. It was just within reach to create the single-action revolver 16 years ahead of Colt. As it was, the gas-seal for these would have made it impossible but it could have been remedied for the loss of a little velocity.

You can see Ian’s AWESOME video on these at Forgotten Weapons.
