Next Level Armament HORUS 9mm Upper Conversion Kit

Next Level's Horus 9mm Upper Conversion Kit combines their Radial Delay Blowback 9mm PCC upper with CMMG's 9 AR magazine adapter. The CMMG 9 AR adapter converts a Gen2 or Gen3 PMAG into an AR15 9mm magazine. No need for bulky magazine well adapters, no need for Glock-specific 9mm magazines, and need to add a fixed ejector. Just change out the follower and spring on the original PMAG and you are ready to roll. The adapter is specifically designed for the Radial Delay Blowback (RDB) system and will hold open on empty. The NLX Horus 9mm PCC features the Radial Delay Blowback system and is a perfect mate for the magazine adapter. They build their Horus uppers on their Ascend Phoenix uppers, so it mates perfectly on your Ascend Phoenix rifle. The Horus Upper will also work on any other mil-spec AR15 lower receiver. Whether you want to train on your AR15 keeping the same feel but with the reduced cost of 9mm ammo, or you simply desire a 9mm PCC, you can't miss with Next Level's Horus 9mm Upp
