Magpul PMAG 30 AR 300 B GEN M3 — .300 AAC Blackout 30-Round Magazine (Black)

Description

The Magpul PMAG 30 AR 300 B GEN M3 is purpose-built to handle the unique geometry and performance of .300 AAC Blackout. Unlike modified 5.56 magazines, this model features redesigned internal dimensions for consistent feeding across bullet profiles and load types.
Constructed from Magpul’s advanced impact-resistant polymer, the magazine includes a stainless steel spring, four-way anti-tilt follower, and tool-less disassembly for easy maintenance. A flared floorplate aids handling, and an over-insertion stop protects receivers during reloads. This Gen M3 design maintains compatibility with most AR-15/M4 platforms chambered in .300 BLK.
