Magpul Industries PMAG GEN M3 300 Blackout 20-Rd Black Polymer Magazine

The Magpul PMAG GEN M3 20-round magazine is purpose-built for rifles chambered in 300 Blackout (300 BLK) on the AR-15/M4/M16 platform. Sharing every key feature of Magpul's 30-round 300 BLK PMAG but packaged in a more compact 20-round body, this magazine is sized for increased maneuverability while still delivering the reliable feeding and function Magpul is known for.

The body is molded from impact- and crush-resistant black polymer with the model-specific distinct ribbed design and smoother upper-half texture that visually and tactically separates the 300 BLK PMAG from other GEN M3 variants. Engineered to meet STANAG 4179 interface dimensions, it drops into standard AR-pattern lower receivers and is fully compatible with the AR-15, M4, and M16 family of rifles chambered in .300 AAC Blackout.

Carrying Magpul part number MAG1182-BLK, this PMAG 20 AR 300 B GEN M3 holds 20 rounds and is made in the USA. It is the ideal spare or duty magazine for any AR-platform rifle running suppressed or unsuppressed 300 BLK ammunition.
