Promag
The ProMag COLA1 AR-15 30-round magazine in blued steel is built to keep you shooting longer between reloads. Chambered for .223 Rem/5.56 NATO, this American-made magazine delivers the capacity competitive shooters, tactical trainees, and range regulars need for extended sessions without constant magazine swaps. Whether you're running drills, working through a practice session, or competing, the 30-round count lets you focus on your shot process instead of logistics.
ProMag engineered this magazine around dependable feeding—a chrome silicon wire spring maintains consistent tension cycle after cycle, while the anti-tilt follower design keeps rounds aligned and feeding smoothly into the chamber. That attention to feed reliability means fewer jams and fewer surprises downrange. The heat-treated steel body is finished in a clean blue oxide that resists wear and corrosion, and the textured surface gives you a confident grip even when your hands are wet or slicked up.
Handling is straightforward: the magazine is sized for quick changes, and it's designed to drop free from your rifle when you hit the release—no fumbling, no stuck mags. The sleek blued finish looks right at home on virtually any AR-15 setup, adding a professional, no-nonsense aesthetic to your platform.

The ProMag COLA1 is chambered for .223 Rem/5.56 NATO and is designed for standard AR-15 platforms. It should fit any modern AR-15 lower receiver using standard magazine wells. If you have a proprietary lower or non-standard platform, confirm compatibility before purchase.
The anti-tilt follower keeps rounds stacked consistently and prevents them from tilting or binding as they feed into the chamber. This design detail directly reduces the risk of jams and misfeeds, which is especially important during competition, training, or any high-round-count session where reliability matters.
The heat-treated steel body and chrome silicon spring are built for durability. With normal maintenance and use, this magazine is designed to handle extended shooting sessions and regular reloading without degradation. The blued finish resists corrosion, which helps extend service life in various conditions.
You receive one ProMag COLA1 30-round magazine, finished and ready to load and run.
