20 Round Magazine - Great for bench or prone shooting. 

The PMAG 20 AR 300 B GEN M3 is specifically designed for rifles chambered in .300 Blackout® (300 BLK). It closely resembles our PMAG 30 AR 300 B but offers a more compact design, enhancing maneuverability and creating a concealable package suitable for small-format firearms.

Traditionally, 300 BLK shooters have had to rely on magazines designed for other cartridges, which limits the round’s overall performance and compatibility. While 300 BLK has historically been compatible with 5.56x45mm magazines, doing so compromises reliability and safety.

The PMAG 20 AR 300 B not only improves performance through its dedicated design but also provides a safer feeding solution for your 300 BLK rifle. When using 5.56x45mm magazines, there’s a risk of chambering and firing a 300 BLK round in a 5.56x45mm rifle, leading to catastrophic results. The PMAG 20 AR 300 B features a distinct ribbed design and smoother upper-half texture, offering visual and tactile differences from other PMAGs to prevent dangerous cross-loading.

Additionally, the PMAG 20 incorporates all the advanced features of our GEN M3 line, including impact and crush resistance, aggressive front and rear textures, an easily removable slim floor plate, and a paint pen dot matrix for marking and identification.

Made in the USA.
