If you're running an AR-platform rifle in .308 Winchester, reliable magazines are non-negotiable—they're the foundation of consistent feeding and function. The ASC 20-Round Stainless Steel Magazine for .308 Win AR Rifles is built to that standard. ASC (Ammunition Storage Components) has earned trust as an approved supplier to major firearms manufacturers by focusing on quality components and engineering that simply works, and this stainless steel .308 magazine reflects that philosophy.

This 20-round .308 AR magazine pairs stainless steel construction with a black finish, giving you a durable, corrosion-resistant feed system that handles the demands of hunting, precision rifle shooting, or tactical training. The magazine is heat-treated for strength and built with a chrome silicon spring—the kind of spec that matters when you're counting on reliable extraction and feeding under pressure. Whether you're loading for a long-range hunt or running transitions at the range, you want a magazine that doesn't introduce variables.

Made in the USA, this magazine fits the bill for shooters who prefer domestic manufacturing and proven reliability over trendy alternatives.
