The Sons Of Liberty Gun Works Mk1 Car SBR 5.56 NATO with 11.5" barrel is a compact, purpose-built AR platform designed for shooters who want a refined short-barreled rifle. Built on SOLGW’s billet MK1 receiver set with a continuous Picatinny top rail and 10.75" MK1 M-LOK handguard, this rifle combines a chrome-lined 41V50 medium-contour Recce P3 barrel, HUXWRX muzzle device, and Liberty 2-stage trigger to deliver smooth cycling, excellent durability, and consistent accuracy in a black anodized package.

This Mk1 Car SBR is chambered in 5.56 NATO and uses a carbine-length gas system tuned around an A5H2 buffer and A5 receiver extension for controlled recoil and reliable function. The Badger ambidextrous safety, Liberty charging handle, MK1 maritime bolt release, B5 grip, and Magpul MOE-TR stock provide ergonomic control for training, range use, and general defensive applications where a shorter, maneuverable rifle is preferred. Sons Of Liberty Gun Works is known for rigorous testing, thoughtful component selection, and hard-use craftsmanship that inspires confidence shot after shot.
