The Sons of Liberty Gun Works MK1 CAR Pistol, 5.56 NATO, 11.5" Chrome-Lined P3 Barrel delivers a purpose-built AR pistol platform centered around SOLGW’s billet MK1 receiver set and 10.75" MK1 DriveLock M-LOK rail. Its medium contour chrome-lined 4150 barrel with 3-groove polygonal P3 rifling, conservative gas porting, and HUXWRX-compatible threaded muzzle is tuned for durability, accuracy, and smooth recoil alongside the A5 buffer system and NP3-coated bolt carrier group.

This MK1 CAR Pistol configuration adds the distinctive MK1 camo Cerakote finish, B5 grip, and SB Tactical SBA5 brace, creating a compact, controllable firearm well suited for home defense, vehicle carry, and intensive range training. Integrated cable routing, laser-textured rail surfaces, and ambidextrous controls support confident handling, while Sons of Liberty Gun Works’ meticulous assembly and testing underscore their reputation for hard-use reliability and refined craftsmanship.
