La France M16K-45, a .45 ACP submachinegun.

Looks like something someone made in their garage.
The upper receiver is definitely all made by La France. The boxy Fisher-Price looking carry handle is quite distinct. All sources say the lower is also proprietary, but I’m pretty sure they at least started with an existing 80% lower and modified it given how standard all the fine details look, and how drastically different the machining is to the upper.
How many feet until the bullets start tumbling on that?
It’s firing .45 ACP (Automatic Colt Pistol), a pistol cartridge, out of a 7.5 inch barrel. It is stabilized. For comparison the standard size 1911 has a 5 inch barrel, the Kriss Vector SMG has either 5.5 or 6.5 inch barrel (depending on model), and the M3 Grease gun has an 8 inch barrel.
Why am I fully erect?
I truly don’t know but please don’t touch the La France hardware with it.
