Bushmaster upper with a 16 inch barrel. No bolt/carrier/charging handle. No flash hider and not threaded for one (it's a postban). Stamping on barrel reads: B MP 5.56 NATO 1/9 H BAR. (Heavy barrel with 1/9 twist)Excellent condition. I bought the complete AR used and replaced the upper with a 24" Bull barrel upper. Not sure on the round count, but I've got an A2 with 180 rounds through it, and I can't tell the two apart as far as finish/bore/rifling.
Leupold VX II or III scopes.
