D&H 300 Blackout AR Magazine

D&H Tactical has started manufacturing an AR magazine with a slightly modified rib suitable for use with .300 AAC Blackout. Although the cartridge is designed to work with standard AR mags, certain .308 diameter projectiles don’t feed perfectly within the confines of a standard 5.56 AR-15 magazine. This product will probably appeal most to those who handload .300BLK, but when D&H catches up on magazine production – they’re currently backordered through the end of March – it might be worth grabbing a few even if you shoot factory ammunition.
