I have for sale a factory Colt 16" Hbar flat top upper assembly (AR6721). The upper receiver has the "T" numbers in the rail and M4 feed ramps. The upper receiver is marked "M4" above the gas tube hole. The barrel is marked "C MP 5.56 NATO 1/9 HBAR", "F" marked front sight tower, and the "4" marked chamber. Condition is absolutely new. Does not include the bolt carrier assembly, charging handle, or carry handle (as pictured).
Price is $SPF shipped. I will accept PayPal or a USPS money order. No trades at this time.
The upper is SOLD, pending receipt of funds. Thanks.
