BKF M5 MOD-0 LR-308 18″ .308 SL-S Rifle

Description

The BKF M5 MOD-0 LR-308 18 Inch Rifle is a premium billet AR-10 platform engineered for shooters who demand precision, durability, and professional-grade performance. As part of B. King’s Firearms Premium Series, this rifle is designed with the AR builder in mind, combining refined aesthetics with combat-ready components.

The foundation begins with a precision-machined 7075-T6 billet lower receiver featuring a right-side bolt release and enhanced contours for a clean, professional appearance. A 4.5 lb two-stage trigger and A5 9-position buffer system with H2 buffer provide a smooth, controlled shooting experience tailored to the rifle’s gas system and caliber.

Up top, the thermal-fit billet upper receiver ensures optimal barrel alignment and rigidity. The 18″ .308 Win tactical government-profile barrel is paired with a mid-length gas system for balanced recoil and reliability. A duty-grade M-LOK handguard with anti-rotation tabs, multiple QD points, and Picatinny sections at the 3, 6, and 9 o’clock positions allows flexible accessory mounting.

A high-pressure tested and MPI-inspected nitride bolt carrier group, Breek Arms Sledgehammer ambidextrous charging handle, and BKF Mk2 compensator work together to enhance reliability while significantly reducing felt recoil. Finished with a Magpul SL-S stock and MOE pistol grip, this rifle delivers comfort, balance, and consistent performance.

BKF guarantees 1 MOA or better accuracy with match-grade ammunition, making the M5 MOD-0 LR-308 an exceptional choice for precision shooting, duty use, or a premium AR-10 build.
