Description

BKF M4A1 SOPMOD Block 2 14.5 Inch 5.56 Rifle

The BKF M4A1 SOPMOD Block 2 14.5 Inch 5.56 Rifle is a modern, duty-grade build inspired by the SOPMOD Block II configuration developed for United States Special Operations Command. This rifle reflects the evolution of the M4A1 platform used by special operations forces, combining rugged construction with modular capability.

At its core is a 14.5″ 4150 chrome moly vanadium barrel with a 1:7 twist rate, carbine-length gas system, and F-marked front sight base. An extended flash hider is permanently pinned and welded to achieve a legal overall barrel length exceeding 16 inches, allowing use on a standard lower receiver without NFA registration. The barrel features a QPQ corrosion-resistant finish for extended service life.

The rifle is equipped with a Midwest Industries extended-length two-piece free-float quad rail, providing ample space for lights, grips, and mission-essential accessories. A B5 Systems SOPMOD Government stock in coyote brown and Magpul ladder rail covers complete the Block II aesthetic.

Forged upper and lower receivers are machined from 7075-T6 aluminum and finished in hardcoat black anodizing with M4A1-style selector markings. Additional components include an MPI/HPT-tested M16 bolt carrier group with nitride finish and mil-spec fire control group. Each rifle is assembled and test-fired in the USA using BKF components to ensure consistent performance.

BKF M4A1 SOPMOD Block 2 14.5 Inch 5.56 Rifle features forged 7075-T6 M4A1 receivers, a 14.5″ 1:7 twist 5.56 NATO barrel with pinned flash hider, carbine-length gas system, SOPMOD stock, free-float quad rail, and SOCOM-style Block II configuration.
