The Magpul PMAG 30 AR 300 B GEN M3 is a dedicated 30-round magazine designed specifically for AR-platform rifles chambered in 300 Blackout. Built with Magpul's durable GEN M3 polymer construction, this magazine is engineered to support the unique bullet profiles and cartridge geometry commonly found with 300 BLK ammunition.
This magazine features optimized internal geometry for improved 300 Blackout reliability, along with a distinct exterior rib design that helps provide a visual and tactile difference from standard 5.56 PMAG magazines. This makes it easier to identify your 300 BLK magazines and helps reduce the risk of dangerous cross-loading.
This product family is available in multiple color options, including Black, Flat Dark Earth, and OD Green.
