Heckler & Koch MR556 5.56mm NATO 10rd Magazine Black

The Heckler & Koch MR556 5.56mm NATO 10-round magazine is built for AR15-pattern rifles and other modern sporting rifles that accept standard 5.56 NATO magazines. Whether you're running an M4-style carbine, an M16-pattern rifle, or a civilian AR platform, this H&K magazine delivers dependable ammunition feeding with the kind of attention to detail you'd expect from a manufacturer with serious military and law enforcement roots. The 10-round capacity makes it a practical choice for shooters who value reliable function without excessive bulk.

H&K engineered this magazine around proven fundamentals: quality steel construction, a well-designed follower, and spring material selected for consistent performance across thousands of rounds. The magazine features an anti-friction maritime surface finish—a detail borrowed from H&K's duty-weapon heritage—that resists corrosion and reduces drag during loading and feeding. Tight production tolerances throughout the assembly ensure that feed lips maintain their geometry and that the magazine seats and functions dependably, cycle after cycle.

Reliability matters when your magazine is the link between your rifle and the round. This H&K 10-rounder is engineered to feed without compromise, whether you're at the range, in the field, or training for a specific mission. If you shoot an AR15-type rifle and want magazines built to exacting standards, this is the kind of hardware that pays for itself in peace of mind.
