The Magpul PMAG 30 AR 300 B GEN M3 is engineered specifically for rifles chambered in .300 Blackout. Unlike standard AR magazines designed for 5.56x45mm, this dedicated magazine addresses specific challenges associated with the .300BLK cartridge, particularly its wide range of projectile weights and profiles. Historically, shooters have utilized 5.56 magazines, which can lead to compromises in reliability and feed performance.
Optimized Performance and Safety
This PMAG model enhances feeding consistency for .300 Blackout rounds, accommodating various subsonic and supersonic loads with greater reliability. A primary safety benefit is its distinct physical design. The PMAG 30 AR 300 B features a unique rib pattern and a different texture on its upper half compared to other PMAGs. This provides a clear visual and tactile differentiation, helping shooters prevent the dangerous cross-loading of a .300 Blackout cartridge into a 5.56x45mm firearm. Such an error can result in severe firearm damage or injury.
Constructed from durable polymer, this magazine maintains the robust performance expected of Magpul firearm accessories. It offers a 30-round capacity and is an essential component for any .300 Blackout platform, whether for precision rifle applications, hunting, or general use at the shooting range. Its design supports consistent feeding, critical for dependable operation.
