I have a preban colt A3 16" HBAR marked C MP 5.56 NATO 1/9 HBAR on the barrel and C AF on the receiver, it also has "M4" stamped above the gas tube on the receiver as well. The bolt carrier has a "C" stamped on it. The barrel is a complete HBAR even underneath the handguards. I have the oversized M4 handguards on it but will include the car style as well. I have never shot this upper but I got it used so I have no idea how many rounds have been through it. I just had it professionally refinished by Rapid Fire of Ohio and it LOOKS new. It has an A2 suppressor attatched. I believe this to be the 6721C tactical conversion upper. If you know more about this email me with questions and I will answer them as best as I can.
All Colt A3 upper complete $600.00 shipped
