The one pictured is a more modern model, but the original L96 is, with 90s era machine tools, the one that’s probably easier to make in a garage. All the stampings on the sten are substantially more difficult to create as a one-off, but the action on the L96 just needs a lathe and a broach or EDM, all the rest of it a series of very simple milled components and a composite stock that you could build a mold for out of fiberglass and Bondo.
