'Table Leg Typewriter' DIY submachine gun prototype

by ImproGuns

Sent in to TFB is another concept design for an ‘afternoon’ DIY submachine gun of particular crudeness and expediency. The majority of components are laminated together from readily available square section steel tubing, owing to its namesake. Apparently the only thing that cost anything was the STEN mag and compression spring. The model shown is a non-firing mock-up dummy for the purposes of demonstration only.

The trigger in this case is an absurdly simple arrangement consisting of a rectangle and square plate which pivot together.

Rather than being milled from a single piece, the bolt consists of a bar bolted into two lengths of square steel tubing.

The barrel collar is a near identical arrangement and includes an integrated feed ramp ground into it.

For those interested in academic study, a detailed look at its construction can be seen here.

    Looks like something that would have been made for the OSS in the 40s, or an even cruder version of the Sten.

    Pre-orders are now being accepted at your local black market street gun dealer in all major cities in the gun-free Eurozone. I look forward to seeing one of these table leg machine guns in the pile of weird homemade guns confiscated from petty criminals in Europe. Someone should hand carve an HK logo on them. The Beretta logo is too complicated.

    Also available for US$125 from several shed based firearms manufacturers on the outskirts of Danao in the Philippines.

    3D printed small parts kit available 1Q16. Search eBay and Craig's List for "typewriter repair kit".

    We just need MORE gun control laws, because 44,000 aren't quite enough. :-/
