The Troy BattleMagA(R) is one of the best polymer magazines in the world. The BattleMag is engineered to function flawlessly with all M4, M16/AR15, HK416A(R) and FN SCARA(R) rifles and carbines. An aggressive scale pattern provides the ultimate magazine grip in dirty or wet conditions. A bolstered floor plate is set flush to eliminate the BattleMag from catching on other magazines or creating unnecessary bulk when stacked or pulled from a pouch. The reinforced feed lips and anti-tilt follower do not require a clamp to keep the feed lips from spreading when kept loaded for extended periods of time. Made from improved Troy proprietary military-grade, chemical, biological and impact resis Mfg: Troy Industries
