Product Info for CMMG Resolute Fixed Ejector 9mm 16.1in Upper Group

RDB was an advancement from straight blowback. Compact action RDB was an advancement to the original RDB. This (fixed ejector on RDB) is a continued advancement bringing new technologies to the original platform. Looking to build the ultimate 9mm pistol caliber carbine? We have you covered! Utilizing our Radial Delayed Blowback operating system, not only does this upper create one of the softest shooting 9mm PCCs with style that is unmistakably CMMG, this upper group is designed to work with a number of different lower receivers. From standard AR15 lowers (when used with AR 9 conversion mags) to any of our pistol magazine lowers (Mk9, MkGs, and Mk17), you can build your next PCC exactly how you imagine.image
