Description

BKF M4 MOD-0 14.5 inch 5.56 NATO SL-S rifle

The BKF M4 MOD-0 14.5 inch 5.56 NATO SL-S rifle is engineered for duty and professional use where reliability, durability, and refined handling are critical. Built entirely in the USA, this rifle utilizes precision-machined 7075-T6 aluminum receivers held to tighter tolerances than traditional mil-spec standards, resulting in improved fit and long-term performance.

The 14.5″ barrel is pinned and welded to 16″ to meet legal rifle requirements while maintaining excellent balance and maneuverability. A mid-length gas system paired with an A5H1-style buffer assembly and Sprinco Green spring delivers smooth, controlled operation. Duty-grade features include nitride internal components, ambidextrous controls, a thermal-fit forged upper receiver, and a pinned gas block with BKF MK1 compensator. Finished with a Magpul SL-S carbine stock, this rifle is guaranteed to deliver 1 MOA accuracy or better with match-grade ammunition and is fully supported by BKF’s lifetime warranty.
