The Amend2 Mod-A AR-15 5.56/.300 BLK 20-Round Magazine, Black (brand part no. 556MODABLK20) brings the classic straight 20-round magazine profile to the AR-15 platform in fiberglass-reinforced nylon, compatible with both 5.56×45 NATO/.223 Remington and .300 Blackout. Amend2 builds the Mod-A with added rigidity that reduces feed lip spread for consistent feeding under demanding conditions, and improved temperature resistance keeps performance steady across a wide range of environments. The straight 20-round profile improves maneuverability for prone shooting, bench use, and compact loadouts, while textured front and rear grip panels give positive control and sleek side panels allow snag-free changes from plate carriers or chest rigs. Amend2 manufactures the Mod-A in the U.S.A. and backs it with a lifetime warranty. Among AR magazines, this Amend2 piece favors AR-15 owners who want a rugged, compact-profile magazine.
