Promag AR-15 / M16 .223 & 5.56x45mm AR Magazine Black Polymer 20/rd

The Promag AR-15 / M16 .223 & 5.56x45mm AR Magazine Black Polymer 20-Round is a purpose-built, domestic-manufactured magazine designed for reliable performance in 5.56 NATO and .223 Remington platforms. Built to strict feeding specifications, this 20-round magazine delivers the magazine capacity preferred by competitive shooters, tactical trainers, and precision rifle operators who prioritize controlled round count and reduced pack weight during extended range sessions or field operations.

Construction centers on a proprietary DuPont Zytel-based polymer body paired with an injection-molded magazine follower and heat-treated chrome silicon wire spring. This material selection balances weight savings against durability, critical for shooters rotating multiple loaded magazines during competition or training. The polymer construction resists corrosion in wet environments and remains unaffected by temperature extremes, eliminating the rust and spring degradation historically associated with steel magazine bodies. The engineering emphasis ensures consistent round feeding across diverse ammunition types and loading techniques without the maintenance demands of older metal designs.

This magazine suits AR-15 rifles, M16 platforms, and modern carbines chambered in .223 Remington or 5.56x45mm NATO. The 20-round capacity bridges the gap between standard-capacity and high-capacity configurations, offering shooters a compromise option that reduces overall weight and profile while maintaining practical round count for target work, qualification courses, and field-ready loadouts. Made in the USA, the magazine integrates seamlessly into existing AR platform inventories without compatibility concerns or feed failures across mil-spec or commercial receiver variants.
