Ruger 90420 AR-556 30-Round Magazine for AR-556/SR-556, .223 Rem/5.56 NATO - Black

The Ruger 90420 AR-556 30-round magazine for .223 Rem/5.56 NATO is a purpose-built cartridge holder for AR-15 shooters who want reliable, American-made magazines without the downtime of constant reloads. Whether you're running drills at the range, hunting, or stocking up for serious practice, a 30-round capacity cuts your reload frequency and keeps your focus on the shot. This magazine is specifically engineered for the Ruger AR-556 and SR-556, though it also fits other AR-pattern rifles that accept standard 5.56 magazines.

What sets this magazine apart is its construction pedigree. It's manufactured in the USA by C Products Defense with a two-part stainless steel body that's robotically welded to hold tight tolerances where it counts—ensuring consistent mag-well fit and zero wobble. The stainless internals resist corrosion, while the black Teflon coating protects the exterior from wear and the elements. The orange anti-tilt follower and stainless spring are tuned specifically for reliable feeding cycle after cycle, whether you're running brass or steel loads.

Handling is straightforward: the textured surface gives you solid purchase for quick magazine swaps under pressure, and insertion/removal is smooth and positive. This is the kind of magazine you grab without thinking and trust to work, whether you're in a competition environment, running desert drills, or just putting rounds downrange in foul weather. Ruger backs these magazines with a 100% replacement guarantee through C Products Defense.
