Sons of Liberty Gun Works M4-EXO3 5.56 NATO AR Pistol - 11.5" - A2 - 1x 30rd Magazine

Sons of Liberty Gun Works' EXO3 5.56 NATO AR pistol is a duty-grade 11.5-inch build that serves in patrol vehicles and at home — premium SOLGW receivers, Carpenter 158 bolt, A5 buffer system, and EXO3 M-LOK rail, configured as a pistol with the proven components SOLGW builds into every firearm in their lineup.

The Sons of Liberty Gun Works M4-EXO3 is a 5.56 NATO AR pistol with an 11.5-inch SOLGW Liberty Fighting Barrel, EXO3 free-float M-LOK handguard, mil-spec 7075-T6 forged upper and lower receivers, ambidextrous Liberty Charging Handle, A5 buffer system with A5H2 buffer, and SOLGW phosphate-coated Carpenter 158 bolt. Muzzle: A2 flash hider, 1/2-28 threaded. Trigger: Liberty Fighting Trigger 5.5–6 lb. Grip: B5 P23. Includes 30-round magazine. HUXWRX QD muzzle device variant.

SOLGW builds the EXO3 to the same component standard they apply across their entire lineup rather than specifying cheaper parts for a pistol-format product. The Carpenter 158 bolt — the steel specification used in military-contract M16/M4 bolts — is individually proof tested with a high-pressure load, shot-peened, magnetic particle inspected, and full-auto fired before leaving the factory, the same quality verification sequence SOLGW applies to their rifle BCGs. The A5 buffer system with A5H2 buffer is correctly tuned for the 11.5-inch mid-length gas system, managing the bolt carrier velocity and dwell time characteristic of shorter-barrel configurations for reliable cycling across the range of 5.56 loads the pistol will see in service. The EXO3 free-float M-LOK handguard provides a 7-sided attachment surface for lights, lasers, and accessories without the barrel contact that standard carbine handguards impose. The mil-spec 7075-T6 forged receivers provide the dimensional consistency and fatigue resistance of military-contract construction. The Liberty Fighting Trigger at 5.5–6 lb with Nickel Teflon coating provides a consistent, durable fire control group appropriate for a duty platform. The ambidextrous Liberty Charging Handle enables manipulation with either hand. The A2 flash hider manages muzzle flash at the 11.5-inch barrel length where flash signature is more significant than on longer configurations.

Carpenter 158 bolt individually HPT/SP/MPI tested and full-auto fired before shipment — the same quality verification sequence as SOLGW rifle BCGs, applied to every pistol unit. A5 buffer system correctly tuned for 11.5-inch barrel dwell time. Free-float EXO3 M-LOK handguard eliminates barrel contact for consistent accuracy. Mil-spec forged 7075-T6 receivers throughout.

The right choice for duty, home defense, and patrol applications requiring a compact 5.56 NATO platform built to SOLGW's full component specification — Carpenter 158 bolt, A5 buffer, Liberty Fighting Trigger, and mil-spec forged receivers in an 11.5-inch pistol configuration.
