to the best of my knowledge as long as it is a pre ban it should be ok. i don't know the status of parts build guns. here's a pic of what i called my "pimp" uzi. a gun done over by a company called the american historical foundation who typically did some gaudy stuff. i bought this at an auction and at the time got it for less than the going rate for A model uzi's. i found a guy that needed it more than me some years ago. the short barrel on the gun is a dummy bbl. the bbl in the case is a 16" bbl which makes the gun a rifle.
