The PMAG 20 300 B GEN M3 AR-15 Magazine is a dedicated for rifles chambered in 300 Blackout. Optimized for 300 AAC Blackout, the PMAG 20 300 B features a distinct rib design and smoother upper texture to set them apart from other PMAGs for quick visual and tactile identification. This AR mag is easy to disassemble and clean for regular maintenance and won't fail you in the field. While standard AR-15 magazines may be used for this cartridge, the potential danger exists to chamber and fire a 300 Blackout round in a 5.56 NATO chamber with catastrophic results.
