      It's Still a Colt!

      Posted by Beau T. on 20th Aug 2021

      Laser engraved lowers have the CR serial number prefix, QR code, Safe/Fire markings on both sides, non-ambi safety selector that is notched on the right side, selector stops, forge flashing in the trigger area and the "web" on the inside between the safety selector and take down pin. It came with an H buffer, the notched hammer, A2 grip, and like the photo, no shoulder stock and no box. Yeah this comes from a different era, but all of these features topped by the scent of the grease tells you it's still a Colt!
