Magpul PMAG GEN M3 Black Detachable 30round 300 Blackout for AR15 Black
- The PMAG 30 AR 300 B GEN M3 is a purpose-designed magazine for rifles chambered in 300 Blackout (300 BLK).
- Since its inception, 300 BLK shooters have had to use a magazine designed for another cartridge, limiting its ultimate performance and compatibility.
- One of the key features of 300 BLK is the compatibility with 5.56x45mm parts, but with the magazine, it is a compromise to do so.
- Due to the wide variety of projectile weights and profiles potentially decreasing overall reliability, a dedicated 300 BLK magazine was a logical step for the PMAG line.
- In addition to the performance gained by a dedicated mag, the PMAG 30 AR 300 B also offers a safer way to feed your 300 BLK rifle.
- When using 5.56x45mm mags, the potential to chamber and fire a 300 BLK round in a 5.56x45mm rifle with catastrophic results requires diligent ammunition management by the shooter.
- The PMAG 30 AR 300 B’s distinct rib design and smoother upper-half texture provides the shooter a distinct visual and tactile difference from any other PMAG to mitigate dangerous cross-loading issues.
- Along with optimized 300 Blackout performance, the PMAG 30 AR 300 B incorporates all of the GEN M3 features such as our next-generation impact and crush resistant polymer, aggressive front and rear texture, an easily removable slim floor plate, and a paint pen dot matrix for marking and identification.
