ProMag AR-15 Magazine .223 Blued Steel 5/rd

The ProMag AR-15 Magazine .223 Blued Steel 5-Round is a compact, reliable feed system engineered for AR-15 platforms chambered in .223 Remington and 5.56×45mm NATO. Built on the proven G.I. 20-round magazine platform, this 5-round variant delivers the same dependable function in a smaller footprint, making it ideal for controlled range sessions, precision shooting drills, and operational environments where single-feed operations or low-capacity restrictions apply.

The magazine body is constructed from heat-treated steel with a black oxide finish, a proven mil-spec coating that resists corrosion and maintains reliability across extended field deployment and harsh environmental conditions. Internal components include a chrome-silicon wire spring—the same material spec used in military-grade feeding systems—paired with a precision-molded polymer follower. This combination ensures consistent, positive round advancement without chatter, stalling, or erratic feeding that can degrade accuracy during critical shooting sequences.

This 5-round configuration serves shooters operating under legal capacity restrictions, law enforcement agencies conducting controlled training with reduced load-outs, and precision rifle competitors managing mag changes during timed events. The compact magazine reduces weight and pack volume without sacrificing the proven feeding geometry of the standard platform. Operators and range instructors value this design for its interchangeability with existing .223/5.56 magazine-fed platforms and its track record of zero-failure operation under real-world conditions.
