When using a regular AR-15 magazine with 300 Blackout cartridges, the greater width of the 300 BLK's neck and bullet can cause the rounds to stack improperly, and even limit the capacity of the magazine to less than its intended amount.
This is why the purpose-built Magpul 300 Blackout 30-round PMAG exists, to provide perfect reliability and functionality.
Magpul has applied all its generation three advancements to this magazine, including the proven rugged Magpul polymer, aggressive texturing in the front and rear, easily interchangeable floor plate, as well as a paint pen matrix for identifying or marking, and a dust/impact cover.
