DuraMag SS AR-15 .350 Legend Magazine | 20-Round Stainless Steel | Black

Feed your .350 Legend build with confidence using the DuraMag SS 20-Round AR-15 Magazine — the only purpose-built magazine engineered specifically for the .350 Legend cartridge. Unlike generic AR-15 magazines, the DuraMag SS features caliber-specific rib geometry designed to ensure reliable feeding and proper round stacking, eliminating the feeding issues that plague standard magazines when used with this cartridge.

Constructed from premium 410 stainless steel and finished with DuraMag’s proprietary T-360 coating, this magazine is built to perform through the harshest environmental and temperature conditions without flexing, swelling, or degrading — a common failure point with polymer alternatives. The advanced interior and exterior geometries work together to deliver consistent, reliable feeding round after round.

For quick and easy identification, both the magazine body and follower are clearly marked with “.350,” so there’s no second-guessing when your gear is on the line. The DuraMag SS is also rated safe for extended storage while loaded, so you can keep your magazines stage-ready without worrying about spring fatigue or body deformation over time.
