ProMag RollerMag Magazine AR-15 223 Remington, 5.56x45mm, 300 AAC Blackout Polymer

The ProMag RollerMag AR-15 magazine brings a proven feeding design to your rifle platform in a durable polymer package. Built for .223 Rem, 5.56x45mm, and .300 AAC Blackout, this magazine swaps out the traditional follower for an anti-tilt roller follower that keeps rounds level as they feed into the chamber. If you run an AR-pattern rifle and want reliable operation without breaking the bank, a roller follower magazine is a smart, time-tested choice—and ProMag's made-in-the-USA construction backs that up.

The body is molded from DuPont Zytel, a polymer engineered for durability and longevity in the field and on the range. The feed spring is heat-treated chrome-silicon wire, designed to deliver consistent pressure through the magazine's service life. An all-black finish rounds out the package, keeping things practical and low-key. Roller follower magazines have a solid track record among shooters who want to minimize feeding issues, especially in rifles that see regular use.

Available in multiple capacities to suit your needs—whether you're loading light for hunting, running practice drills, or setting up for a range day—the RollerMag gives you flexibility without compromise. If you've had trouble with traditional followers or just want the peace of mind that comes with a proven design, this is a solid, affordable choice for your AR platform.
