Definitely beyond prop "replica" on this one. Definitely worth the class 3 license but if you want to make a semi-automatic model, you'd have people lining up around the block.
Definitely not a Thompson, and it can't be a "new" gun because of restrictions. In the US no civilian can own a machine gun manufactured after 1986. That doesn't rule out a modified gun, because the receiver would still be pre-ban.
The mag looks double stacked and I'm leaning toward 9mm.
Yeah the cool thing is the gas from one gun powers the other gun and vice versa.holy **** on that second mod. two stacked on top of each other. I know it'd be heavy, but jeez.
If you're a manufacturer though you can make some cool pet projects like these here for pure fun:

I thought this may have been something similar.
What kind of recoil dampening do you have in that thing? It doesn't look like it moves at all.
