The ProMag RollerMag Magazine is a polymer AR-15 magazine engineered to feed reliably across multiple cartridge types—.223 Remington, 5.56x45mm NATO, and .300 AAC Blackout—making it a versatile choice for shooters who run different uppers or barrel configurations on the same lower receiver. Unlike traditional magazine followers that can tilt under spring tension and cause feeding problems, the RollerMag uses an anti-tilt roller follower that keeps rounds level and properly positioned as they feed into the chamber, reducing the risk of misfeeds during rapid fire or in less-than-ideal conditions.
Built from DuPont Zytel polymer, the magazine body is tough enough for hard use at the range, in competition, or in the field. The follower rides on a heat-treated chrome-silicon wire spring that maintains consistent upward pressure throughout the magazine's life, whether you're running it half-full or loaded to capacity. ProMag manufactures these magazines in the USA and finishes them in black, so they blend seamlessly with most modern rifle builds.
Available in multiple capacities from 5 to 40 rounds, the RollerMag lets you choose the load count that suits your mission—whether you're target shooting, hunting, or training. The anti-tilt design is especially valuable if you've had feeding issues with polymer mags in the past; the roller follower is a simple but effective fix to a common problem.

Yes. The RollerMag is designed to feed .300 AAC Blackout, as well as .223 Remington and 5.56x45mm NATO, so you can use the same magazine across multiple uppers without worrying about compatibility.
The anti-tilt roller follower keeps rounds level and properly aligned as they feed into the chamber. A traditional flat or slightly curved follower can tilt under spring pressure, especially as the magazine empties, which increases the risk of a round nose-diving or catching on the feed lips. The roller design prevents this tilt, resulting in more consistent feeding.
ProMag offers the RollerMag in capacities ranging from 5 rounds to 40 rounds, so you can select the capacity that fits your use—whether you need a low-round hunting mag or a high-capacity range or competition mag.
Yes, ProMag manufactures the RollerMag in the USA and finishes all models in black.
