Description

BKF-15 20 556 FSB Rifle

The BKF-15 20 556 FSB rifle is designed for shooters who value a traditional full-length AR-15 configuration with modern build quality. Constructed entirely from 100% USA-made parts, this base-model BKF rifle offers smooth recoil, durability, and classic styling in a no-logo lower receiver platform.

Rifle-Length Gas System and Fixed Front Sight

This rifle is built around a 20″ 4150 CMV barrel with a 1:7 twist and a pinned fixed front sight base (FSB) with triangle cap. The rifle-length gas system provides softer recoil impulse and consistent cycling, making it ideal for extended range sessions and precision-focused shooting.

Built for Accuracy and Heavy-Duty Use

B. King’s Firearms barrels are manufactured by a top-tier barrel manufacturer to BKF specifications and built for combat and heavy-duty use. All pinned gas block models are rated for full-auto use, and BKF guarantees 1 MOA or better accuracy when paired with match-grade ammunition.

Classic A2 Rifle Configuration

An MPI-tested M16 bolt carrier group, mil-spec rifle buffer assembly, and billet charging handle ensure reliable operation. The rifle is completed with a BKF A2 rifle stock and grip and retro rifle-length two-piece handguards, delivering a timeless AR feel with modern reliability.

Whether you’re looking for a classic service-rifle configuration, a smooth-shooting range rifle, or a dependable AR-15 built the traditional way, the BKF-15 20″ FSB rifle delivers proven American-made performance.
