Magpul’s PMAG 20 AR 300 B GEN M3 delivers purpose-built performance for .300 Blackout (300 BLK) AR-platform rifles. Built on the same proven design as the PMAG 30 AR 300 B, this 20-round capacity magazine offers a more compact footprint that enhances maneuverability and reduces overall profile in small format firearms. The magazine features a distinctive ribbed design and smoother upper-half texture that provide clear visual and tactile distinction from other PMAG variants, helping prevent dangerous cross-loading in the field.
