The CMMG 10-round 9mm AR-15 magazine is purpose-built for shooters running a 9mm AR upper on a standard Mk4 or AR-15 lower receiver. If you've invested in a CMMG 9mm Radial Delayed Blowback upper, you need magazines engineered to feed reliably with that platform—and this polymer magazine does exactly that. The 10-round capacity keeps you compliant in states with capacity restrictions while giving you a useful payload for training, home defense, or competitive shooting.
The smart design here is the form factor: exterior dimensions match standard 5.56 AR-15 magazines, so these 9mm mags work seamlessly with the mag pouches, carriers, and chest rigs you already own. No need to buy new gear just because you switched calibers. The black polymer construction is tough, lightweight, and resists corrosion—ideal for guns that see regular use and occasional neglect.
CMMG's Gen II magazine design reflects years of refinement in the AR-9 space. These aren't an afterthought; they're the factory-matched magazine for your rifle platform. Whether you're building out a duty carbine, setting up a competition rig, or maintaining a reliable truck gun, having dedicated, proven magazines eliminates one variable from the reliability equation.
