The Troy BattleMag is engineered to function flawlessly with all M4, M16/AR-15, HK416 and FN SCAR 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. An extended floor plate lock is also included, which helps absorb shock when the magazine is dropped free during a reload. 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 resistant polymer and extensively tested by Special Ops units.
