Shooters know that longer sight radius’ allows the shooter to draw a better sight picture, improving accuracy. The Tac2 is built on that foundation. Featuring Magpul's ACS stock, Moe Grip, and back-up sight and DPMS’ new M111 modular handguard system, this carbine is equally suited for use in a multi-gun competition or a tactical defense situation. The Tac2 utilizes a full-length gas system for minimal felt recoil. The 16" 4150 steel barrel is chrome-lined for durability. Forged 7075 T6 A3 flattop upper receiver. Forged 7075 T6 lower receiver. A2 post front sight. Panther flash hider. 1 in 9" twist.
