id like to trade my recently built ar for an uzi or mac (semi auto) in 9mm. It was built on a stag arms lower, with a stag LPK, and a complete RRA car a4 flat top upper It has an AMRS 40L b.u.i.s. and an armalite 4position collapsable stock . email me for pics or more info on the rifle. if you have something like an UZI or MAC carbine, or pistol, in 9mm. ideally with lots of mags, cleaning stuff and a case, but let me know what you got to trade. the worst i can do is say no.
