The Troy BattleMag is the best polymer magazine in the world – hands down. The BattleMag is engineered to function flawlessly with all M4 M16/AR15 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. 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 the Troy BattleMag outperforms all other polymer magazines in functionality and reliability. Includes a flush and shock absorbing extended floor plate lock – a $5 value. Available in Black. Note: Only Available in Caliber 223/5.56.
