It’s what we called “The Franken-gun.” At first, I thought that this was just some cobbled-together oddball that one of my friends had picked up somewhere – a refugee from some amateur gunsmith’s bench. But it turns out it was a fairly accurate reproduction of another fabled WWII gun, which itself had been cobbled together for a very specific purpose.
The original was the De Lisle Commando Carbine, a bolt-action, short-barrel carbine designed to be as quiet as possible. See, it also had a substantial suppressor built into the long ‘can’ on the gun. It was purportedly so quiet that the loudest sound it made was the firing pin striking the primer – quiet enough that it couldn’t be heard at all at 50 yards, the effective operating range of the gun.
The original had been a wartime project meant for British commandos, made using parts from a Thompson SMG (the barrel), a short-action Lee-Enfield Mark III (the receiver/action) and modified magazines from an M1911. I’m not sure where the stock came from on the original. It proved successful, but only about 130 of the guns were made.
