The base parts for this build came from an AGM Sten MkII, the gearbox and modified hop unit. 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. 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. From the original Sten MkI, to the obscure Sten MkIV and the frankly weird Cornershot Mk5 I’ve built a few. I’ve both seen and built quite a lot of different models of Stens.
