ProMag AR-15 9mm Polymer Magazine, 32-Round

ProMag AR-15 9mm Polymer Magazine

This 32-round magazine represents a practical approach to AR-15 9mm ammunition storage. ProMag's hybrid construction combines the best attributes of steel and polymer materials.

Design Features

Hybrid Construction

• Stamped steel upper section provides durability where it matters most
• Over-molded DuPont Zytel polymer body reduces weight while maintaining strength
• This combination delivers reliability without unnecessary bulk

Internal Components

• Injection-molded magazine follower ensures consistent feeding
• Heat-treated chrome silicon spring maintains tension and reliability through extended use
• Precision engineering throughout the feed system

Practical Considerations

The 32-round capacity makes this magazine suitable for training sessions, competition shooting, and general range work with 9mm AR-15 platforms. The polymer construction keeps weight down, while the steel reinforcement in the upper section resists wear from repeated loading and unloading.

This magazine works specifically with AR-15 platforms chambered in 9mm and is not compatible with standard 5.56mm or .223 Remington AR-15 magazines.

Reliability

ProMag's engineering focuses on straightforward functionality. The heat-treated spring maintains consistent pressure, and the hybrid materials resist the degradation that can occur with all-polymer designs.
