Promag Colt Ar15 223rem 42rd Blk

The ProMag Colt AR15 223rem 42rd Black magazine is a high-capacity feeding solution specifically designed for AR-pattern rifles chambered in .223 Remington and 5.56 NATO. With a capacity of 42 rounds, this magazine allows for fewer reloads during extended range sessions, training drills, or field operations.

ProMag magazines are manufactured and assembled in the USA and backed by a lifetime guarantee against manufacturer defects, making this a dependable choice for serious shooters. The magazine features a precision-wound spring constructed from heat-treated chrome silicon wire, which resists fatigue and maintains consistent feed tension across thousands of cycles.

AR-15 owners building patrol carbines, match rifles, or recreational platforms can benefit from the extended capacity, but should verify compatibility with their specific upper and lower receiver combination before use. The lightweight black polymer construction ensures durability, making it suitable for competitive environments, training scenarios, or duty-ready configurations.
