The CMMG 9mm Gen II magazine for Mk4/AR15 platforms is built for shooters who've chambered their AR in 9mm using CMMG's Radial Delayed Blowback upper receiver. This 33-round 9mm magazine feeds reliable, consistent rounds downrange without the usual magazine changes that come with standard-capacity alternatives. Whether you're running a dedicated 9mm AR for training, competition, or home defense, this magazine gives you more shots per reload while maintaining the familiar form factor of standard AR-pattern mags.
One of the standout traits of the Gen II design is its cross-compatibility with existing 5.56 AR15 magazine pouches and carriers. The exterior dimensions closely match conventional 5.56 magazines, so you won't need to overhaul your loadout gear—just swap in these high-capacity 9mm feeders and keep running. The improved Gen II design steps up from earlier 30-round generations, delivering the extra capacity shooters demand without unnecessary bulk.
Built with CMMG's attention to detail, these magazines are engineered specifically for the Mk4/AR15 lower receiver paired with a CMMG 9mm Radial Delayed Blowback upper. If you're running that platform, compatibility is guaranteed. Stock your range bag, duty rig, or competition kit with the extra firepower these 33-rounders bring to the table.
