ProMag's innovative product line stretches across many firearm platforms to bring shooters unique parts and accessories for upgrading their favorite weapon. Not getting bogged down in the mundane, ProMag's out of the box approach has resulted in a plethora of exciting parts to enhance the performance and personalization of iconic pistols, rifles, and shotguns. Their rollermag series reinvents the wheel by adding rollers to a redesigned anti-tilt follower which reduces friction and makes its operation silky smooth. Designed to fit any standard AR chambered for .223/5.56, its 40 round capacity will effortlessly feed and function in your favorite weapon system. The DuPont Zytel based polymer body also features over molded stamped steel feed lips and magazine catch to provide superior strength and stability where it's needed most. If that wasn't enough, the spring is manufactured from chrome silicon wire and heat treated to ensure long term reliability. Anyone looking to increase their AR's capacity and functionality should consider ProMag's 40 round rollermag.
