D&H Industries AR-15 Magazine Features The D&H Industries AR-15 magazine is purpose-built around D&H s proprietary anti-tilt follower a design created specifically to reliably feed the wide heavy-for-caliber bullets used in big bore cartridges like .458 SOCOM. Standard AR magazine followers are not shaped for these oversized projectiles so this dedicated geometry keeps rounds properly indexed and feeding straight into the chamber under recoil. The black anodized aluminum body resists wear from repeated loading and unloading holding up to the abuse of range sessions and hard use in the field. A laser-engraved caliber marking on the body makes it easy to keep magazines sorted when running multiple calibers through similar-looking AR platforms. Aluminum construction keeps the magazine light in a mag pouch while still standing up to drops and rough handling better than many polymer alternatives. The 10-round capacity is calibrated specifically around the dimensions of the .458 SOCOM cartridge so feed lips and follower geometry are matched to the round rather than adapted from a smaller caliber. This magazine fits AR-15 pattern rifles built for .458 SOCOM making it a straightforward spare or replacement for shooters running this big bore platform. D&H s reputation for proprietary big-bore magazine engineering makes this a dependable pick for hunters and shooters who demand reliability from their spare mags.
