PMAG® 20 AR 300 B GEN M3®, 300 BLK

Magpul's PMAG 20 AR 300 B GEN M3 is a tailored solution for shooters using .300 Blackout ammunition. Its compact design improves maneuverability and makes it more concealable, which is an advantage in small format weapons. Traditionally, .300 BLK shooters have been forced to use magazines designed for other cartridges, limiting both the performance and compatibility of the ammunition. The PMAG 20 is constructed with a unique ribbed design and a smoother surface texture on the upper half, giving users a visual and tactile distinction between this magazine and other PMAGs. This reduces the risk of dangerous cross loading with 5.56x45mm ammunition.

The magazine incorporates all the features of the GEN M3 series, including next-generation polymer that is resistant to shock and pressure, aggressive texturing on both front and back, an easily removable slim base plate, and a paint pen matrix for marking and identification. It is optimized for maximum safety and reliability with 300 BLK ammunition and is compatible with most 'STANAG 4179' platforms such as AR15/M4, FN SCAR, IWI Tavor and others​​​​​​
