The Troy BattleMag is as sleek as it is strong. The feed lips and anti-tilt follower are reinforced for strength, and a bolstered floor plate is set flush so that it will not catch on other magazines when pulled from a pouch so operators save crucial seconds when executing magazine changes. It comes with flush and shock-absorbing extended floor plate. The Troy BattleMag is engineered to function flawlessly with all M4, M16, AR15, HK416. This is a pack of 3 BattleMags.
