Troy Industries Battle Mag 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. The floor plate features a shock absorbing pull tab, or can be used with the flush locking plate. Functions with all M4, M16, AR-15, HK416, and FN SCAR rifles.
