Magpul PMAG 30 AR 300 B GEN M3 (.300 BLK) — Lot of Ten 30-Round Magazines
This lot includes ten Magpul PMAG 30 AR 300 B GEN M3 magazines, purpose-built for .300 AAC Blackout (7.62x35mm). The dedicated internal geometry is designed to support the wide range of .300 BLK projectile weights and profiles, with distinct external ribbing and upper-body texture to help differentiate from 5.56 magazines.
GEN M3 construction uses impact- and crush-resistant polymer and includes a paint-pen dot matrix for marking, plus a removable floorplate for straightforward maintenance.
