Hi building a Retro Model 609. I traded a buddy for a A1 Upper receiver. Its a Small Pivot pin hole upper. No brass deflector but has forward assist. The letters PM are on the right side under the rear sight. I know Colts are marked here and I tried to locate these markings in the retro postings but I havent found anything. Any info would be appreciated. Thanks   |
It is a GI replacement upper and is not Colt. |
