Collecting input from military, law enforcement, and civilian shooters, TAPCO Inc. has designed a magazine that can be depended on during a trip to the firing range or deployment overseas. Weapons are only as good as the feeding device used with them, officers can count on the AR 30-round magazine to reliably function in any operational environment. Molded of reinforced composit, its aggressive horizontal ridges provide increased gripping surface for insertion and extraction of the magazine in wet or muddy conditions.
