I have questions on a homebuilt, full-sized, semi-auto Uzi pistol using the short SMG barrel. (Not intended nor wanted to be an SBR build). The desired effect is to recreate an Israeli issue looking Uzi, but still maintain legal pistol status. My questions are about using an original folding buttstock that is welded in the CLOSED position.
Is it legal to mount a welded closed folding stock onto an UZI pistol?
If it is legal, is it also required for it to be welded onto the pistol?
Or does a welded closed buttstock force it into SBR status?
Ideas or comments?
