The ProMag Magazine (RM-40-SL) is built out of polymer and holds a total 40 rounds of 5.56 ammunition. This 5.56 magazine utilizes an enhanced anti-tilt follower with a design that significantly reduces friction for reliable, smooth function with every shot. The Promag RM-30 Rollermag accomplishes this with the rollerfollower that uses a wheel on the follower to prevent it from dragging against the magazine walls. This 40-round polymer AR magazine also features heat treated, chrome-silicon springs for a long service life even eve they are stashed fully loaded.
