Sure can. It either has to be pre-sept 94 or modified. Modified meaning non-folding stock. I think that's the only stipulation with an uzi. Do Vectors have a bayonet lug? IMI's do but i'm not sure about Vectors. In any event, if you ditch one or the other you'll be good as it accepts hi-cap mags. If you dig up one of the many surplus uzi mags, as well, you should be good as they are almost all "pre-ban."
