Miles of TFB TV presents the Sten submachine gun, which has an interesting history to it. This machine carbine was one of the most rushed and most mass-produced submachine guns during World War II. There were over 32 million made. The gun was blowback-operated, carried 32 caliber rounds, and had a wire stock on most variants, with the magazine protruding from the left side.
While the gun was reliable, a lot of shooters did not like it, mainly because they saw it as a cheap, last-ditch effort pipe gun. Nonetheless, there were a number of Sten suppressed versions, and two of the most prominent ones are featured here: the Mk II(S) and the Mk VI with the wooden stock and furniture.
The first suppressed version was the Mk II, with a suppressor that was 22 inches long. This made the gun unwieldy and horrible to hold and use in the operations that British Special Forces were conducting.
The suppressors shown here are important because of the way the Sten is constructed, but these could easily be dismantled with the barrel itself, simply by unscrewing the whole thing. This was a feature present in all the Mk IIs and the Mk Vs, which made them easier to carry around when disassembled.
The Mk II came from various designers, and the S stands for special purposes. It was used by resistance groups in Europe, because it was easy to drop it off, disassembled, and units could pick them up and have ready submachine guns at their disposal.
But one major problem with these suppressed models was that the gun would easily overheat, so in many versions, a canvas guard was placed around the suppressor to keep a shooter’s hands from getting burned. In addition, the bolts on the gun had to be made lighter because they could not cycle properly with the additional pressure from the suppressor.
Miles discusses more on the design of both the Mk II and the Mk V they have, particularly on the suppression systems.
