The Modern Sporting Rifle has come a long way but none as far as the Battle-Light Rifle. The Battle-Light Rifle features ambidextrous controls and Nickel Boron coated bolt carrier group for long term performance. A 1:8 twist barrel means that you can shoot a broader range of projectile weights with confidence. The Battle-Light Rifle has a tuned mid length gas system for a smooth shooting experience no matter what ammo you choose.
