Next Level Armament’s Horus 9mm Upper Conversion Kit combines our Radial Delay Blowback 9mm PCC upper with CMMG’s AR15 9mm Conversion Magazine.  

The CMMG AR15 9mm Conversion Magazine fits into any standard AR15 magazine well.  No need for bulky magazine well adapters, no need for Glock-specific 9mm magazines, and no need to add a fixed ejector.   The Conversion Magazine 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 conversion magazine.  We build our Horus uppers on our 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 Upper Conversion Kit.

Kit includes:

• NLX Horus 9mm RDB PCC Upper- available in 5″, 8″, or 16″ barrel lengths
• 33 rd CMMG AR15 9mm Conversion Magazine

NOTE:  The NLX Horus uses a Radial Delayed Blowback (RDB) system with a BCG that is similar to a standard AR15 BCG.  Therefore, NLX Horus upper  will not work with a lower receiver that uses a traditional AR9 system with a fixed ejector and a one-piece, flat-face BCG.
