Airsoft Sten MkIII

Complete builds, Custom builds, Sten, Sub Machine-guns, Weapons, WWII

I’ve both seen and built quite a lot of different models of Stens. From the original Sten MkI, to the obscure Sten MkIV and the frankly weird Cornershot Mk5 I’ve built a few.

One thing I have never seen is an airsoft Sten MkIII: These were quite common in the Northern Europe campaign and were as simple as British-built Stens ever got. With the exception of the trigger group, bolt and barrel parts, these were entirely stamped steel; making them ideal for mass-production, though presented some difficulty in reproducing in my workshop as a result.

The base parts for this build came from an AGM Sten MkII, the gearbox and modified hop unit.

Inside the receiver the hop unit had to be turned down on the lathe to fit the narrower tube.

The top bar on the original, which holds the foresight, is a seam which is spot welded. On this build this is a separate part welded onto the tube as this is far easier to make without a press-brake.

_DSC9522

The receiver has been made from 40mm ERW tube, I milled out the feed port, ejection port and operating handle slot. I used the original lower reciever and buttstock as these were pretty suitable already.

The back-cap is a modified MkII cap. I ground it down to give it the rounded look of the stamped piece and moved the rear sight to the front of it. I have fitted it with a flat locking screw to replicate the button on the real thing.

Finally, I made the front barrel bushing and cocking handle on the lathe and oil finished the other steel parts. I left most of the welds quite rough-looking to try and carry over the overall feel of the originals.

Sten MkI/MkI* : Complete

Add-on kits, Complete builds, Products, Sten, Sub Machine-guns, Weapons, WWII

Some images of the completed Sten MkI and MkI*. Firstly a picture of AN original for comparison. I should point out that you can find differences between nearly every surviving example so this isn’t definitive:

The main issue with this replica is that the safety catch is at the top of the operating handle slot (as this is based on the AGM Sten MkII). The only way to adequately redo this is to make a whole new receiver unit. Maybe a project for the future…

A close up of the receiver. The new operating handle and bolt also feature the Sten safety switch kit. You can also just make out the Sten MkI stampings on the magazine housing.

_DSF7040

The foresight on this is very comfortable to acquire, at least in the confines of the workshop where I have tested it so far! This will be going out in the field at the weekend.

_DSF7042

The stock is very comfortable compared to the MkII T-stock. That said clutching a thistle is an improvement over the T-stock… But in all seriousness this is a great alternative and is fast becoming a personal favourite.

_DSF7043

One final feature worth noting is the battery compartment. Accessible from the rear, it can just about fit the standard stick battery in it, though a stick lipo would be a far easier fit.

And in the Sten MkI* configuration, once it had been optimised by the Singer company for serial production:

Sten upgrade: Replacement nut

Add-on kits, Cold War, Sten, Sub Machine-guns, Weapons, WWII

The AGM Sten comes with a hex head screw to attach the stock, which also contains the battery compartment.

This has three disadvantages:

  1. It looks appalling
  2. You require a tool to remove the stock/change the battery
  3. It really looks diabolical

_DSF6752

That’s right, it looks so bad it is worth mentioning twice. Fortunately this is easily fixed! The fix Vintage Airsoft offers also means that you can change the battery without any tools at all.

_DSF6618

This piece is all-steel in construction. The edges are knurled for grip, meaning that the replacement screw can be fitted very tightly with just finger strength.

_DSF6617

The corners are taken off for comfort of use.

_DSF6619

The whole piece is oil blacked, which means it has an extremely wear-resistant finish that nicely matches the original painted surface of the gun.

 

You can buy this very handy piece on the Vintage Airsoft Etsy page For a very reasonable price.

Sten pistol grip

Add-on kits, Products, Sten, Sub Machine-guns, WWII

At some point in the Sten’s history, someone must have thought: “This thing is too long, and too easy to handle. Let’s make it shorter and really hard to handle!”

_DSF5242
So they stuck a pistol grip where the buttstock should go and created the iconic shape of the gun (apparently) used by Commandos and Resistance fighters all over Europe.

_DSF5244

So of course I had to make a replica for the Airsoft ASG Sten. This piece is custom-made for Airsoft Stens. It does require the use of LiPo batteries in the receiver as there is no space to hide it in the grip itself.

_DSF5247

The unit is steel and is forged and welded. The piece shown has been oil finished but it can be left plain or painted.

The price is £40, posted within the UK.

Sten suppressor model for Sten MkIIs or MkVs

Add-on kits, Products, Sten, Sub Machine-guns, Suppressed, WWII

A chap on the British WWII airsoft forum asked if anyone had made a suppressor for their Sten, so I obliged to do a post on my prototype silencer!

As with all my Sten kits (released and in development), I wanted to make this a temporary attachment that could be removed when not wanted.

So, how did I make this?

One piece of 40mm OD (Outside Diameter) mild steel pipe makes up the body of the suppressor, nothing fancy about this at all! Inside this prototype there are two square pieces of plywood with holes through the centre.

These slide over the outer barrel of the Sten and fit very snugly indeed. This makes for a very solid silencer as it has all of the strength of the inner barrel to support it.

20141120_215507

The end cap is a piece of ash, cut to rough shape. I heated a spare section of 40mm tube and used it to cauterise the rough cut cap into shape. Now I have the lathe of course I’d just turn it on that! A little epoxy will secure it in place.

_DSF5042

As the weight of the suppressor is taken by the outer barrel, all that is needed to keep it in place is a retaining screw. I used the screw hole that the heat guard uses on the standard ASG Sten.

_DSF5040

A small piece of brass flat bar bridges the gap, obviously this could also be steel.

_DSF5044

Once the canvas heat cover is on, it camouflages this admittedly unsightly joint!

_DSF5045

On this prototype I’ve just stitched the buttonholes roughly, I’ll be putting in some brass eyelets when I have bought a punching kit!

One thing to bear in mind with this conversion, it is aesthetic ONLY. In no way will this quieten your AEG down as most of the sound is created in the motor and doesn’t really travel down the barrel.

The finish is a combination of enamel paint and matte lacquer so that the metal and wood parts match up.

20141125_220841 copy

The production version of this will differ in a few ways:

1. The end cap will be entirely turned on a lathe for shaping

2. The barrel supports will either be plastic or turned round so that they fill the entirety of the barrel

3. The heat shield will have brass eyelets instead of sewn ones

Production versions will be around £50, a post will be forthcoming on completion of the first model! If you fancy a version of this, do drop us a line on: enquiries.vintageairsoft@gmail.com!

Sten loop stock prototype

Add-on kits, Products, Sten, Sub Machine-guns, Weapons, WWII

I got a chance to test my loop stock prototype at the WWII game at Combat South this month, I needed something a bit more comfortable than the T-stock (and frankly better looking!). I took some photos before I had chance to clean the gun after use.

_DSF5012 copy

This prototype is made of flat bar mild steel, I’m working on a way to source and bend some C/U section steel but if it isn’t possible the flat steel doesn’t look bad and is easily stiff enough for use.

As ever, skirmishability comes tied with authenticity on the priority scale. I have provided a plastic brown clip to take the standard stick battery which is concealed in a canvas ‘sock’.

_DSF5015

Although painting the connectors black makes the battery arrangement less visible, I plan to conceal the wires/connectors a bit better in a production version as they are a little unsightly. The problem is that the battery wires are actually a little too long but I will find a solution!

For production I will probably leave the canvas sock plain and allow people to colour them to match webbing or uniform as desired.

As ever, if this post has given you an idea for a project do drop me (Dom) a line on the usual email address: enquiries.vintageairsoft@gmail.com.
