New pre-ban era Colt M4 14.5 inch barrel in absolutely mint condition. This is the same barrel Colt sells to the U.S. military. Yes its really new and has never been fired, inserted, or mounted into a receiver except possibly at the Colt factory. Yes the cardboard straw is still in the barrel. Yes the Colt acceptance mark (white paint spot near the chamber) is still visible. Yes it has all the correct Colt factory markings and features. It is very rare to see one in this awesome condition! The price is firm at $399.00 plus shipping. I will e-mail pics only to a serious buyer. Please contact me via e-mail.
