The Magpul PMAG AR 300 Blackout GEN M3 20-round magazine in black is a purpose-built magazine designed specifically for rifles chambered in .300 Blackout (300 BLK). This compact 20-round magazine offers increased maneuverability and a more concealable package for small format firearms. The distinct rib design and smoother upper-half texture provide visual and tactile differentiation from standard AR-15 magazines, mitigating the risk of dangerous cross-loading. Incorporating next-generation impact and crush-resistant polymer construction, this magazine ensures durability in demanding conditions. The optimized internal geometry accommodates the wide variety of 300 Blackout bullet profiles, while the anti-tilt, self-lubricating follower and long-life USGI-spec stainless steel spring provide reliable feeding.
