Bushmaster A2 upper, Ban Era, 13" barrel with 3" perm-attached "muzzle brake." Similar to the Patrolman uppers. Includes BCG and charging handle. No round counter, but looked new when I got it and has only had about 500 rounds or so downrange during my ownership. Looking at Patrolman uppers on GB ... let's underprice those winning bids somewhat and say $600.00, shipped, within CONUS. Buyer is responsible for being aware of any and all local laws regarding ownership. Will knock $25 off is some sort of FTF is arranged.
