This is an original OEM Top Cocking Upper Receiver complete with the reinforcement ribs and Cobray© Logo. The only modification from the original design is the inclusion of the hole for the barrel roll pin in the trunnion. We found a limited and old supply of the original sheet metal body and front sight and welded in our trunnion. This upper will work with 9mm and 45 acp. as well as Full or Semi Auto guns. This item is a custom order item, please allow at least two weeks for shipping.
Note: Lower receiver and bolt assembly not included.
