7.5" pistol upper. Colt flat top upper marked 7.62x39, but barrelled in 5.56. 6" aluminium free float forearm. No gas tube, or front sight, threaded un-comped barrel. BC/CH not included. In addition, complete pistol buffer spring kit, complete. Exactly 2 rounds through this setup. The AR pistol is not for me. $300 shipped takes it all. Pics avail to send. IM best to reply/inquire. Thanks for looking.
