CMMG AR-15 Magazine Features The CMMG AR-15 magazine is engineered specifically for CMMG s Radial Delayed Blowback 9mm uppers ensuring reliable feeding geometry matched to that system s unique bolt operation. Constructed from durable black polymer it withstands repeated loading and unloading without cracking or losing feed lip tension over time. The 10-round capacity gives shooters in capacity-restricted states or those who prefer a compact profile a dependable option that still runs reliably. CMMG s Gen II magazine design reflects years of refinement on the company s 9mm conversion platform. Because the magazine s exterior dimensions closely match standard 5.56 AR-15 magazines shooters can use their existing mag pouches carriers and range bags without needing dedicated 9mm gear. This cross-compatibility is a practical advantage for shooters who run both 5.56 and 9mm uppers on the same lower receiver platform. For CMMG 9mm Radial Delayed Blowback owners who need a dependable magazine that fits seamlessly into existing gear setups this CMMG magazine is a straightforward reliable choice.
