This is taking geekdom in an very cool direction with a very real, very functional firearm manufactured from not one, but two NFA-registered firearms.
According to the gun’s builder, Lage, Mfg:
MAX-41A: A combination submachinegun in 9mm and short barreled 12 gauge shotgun designed to resemble the M-41A Pulse Rifle from the movie Aliens.
Submachinegun component is a NFA registered SWD M-11/9 with an Anthony Smith style Suomi upper receiver. Magazine used is a Suomi “Coffin” magazine that holds 50 rounds of 9mm.
No modifications or alteration of the M-11/9 lower receiver is required.
Shotgun component is a NFA registered Remington 870 short barreled shotgun.
BATFE letter was obtained confirming this is a legal configuration, prior to manufacturing.

It’s a nice demonstration of their skill, but don’t ask for one. It’s too time consuming, and the company says they won’t build another one at any price.
