The Troy Industries Battlemag is an advanced polymer 30-round magazine for AR-15 style firearms in .223 Remington. The polymers used in the magazine are chemical, biological and impact resistant. The feed lips have been reinforced and the mag uses an anti-tilt follower. The mag body features a aggressive scale texture that provides a sure grip but will also extract from magazine pouches easily. The spine of the magazine is designed to prevent over-insertion common with some polymer mags. Functions with all M4, M16, AR-15, HK416, and FN SCAR rifles.
