>>929455Ive got this Uzi thing that shoots 5.7mm. Its got a 60 round magazine, I haven't seen anything like it online. I know a guy who's got this machine thing that can 3d print them. He got it from someone else who had a machine that can make the one he got. Thats all that can be said about it, its all under the table and I don't think there's any money involved, so I have no idea how far thats gone already.
