The Sons of Liberty Gun Works MK1 CAR SBR is built for shooters who demand a compact 5.56 platform with serious duty-grade performance. Featuring an 11.5 inch P3 chrome lined barrel, this short-barreled rifle is designed to deliver dependable function, extended barrel life, and consistent accuracy in a hard-use package.

At the heart of the MK1 is the Cable Management Rail with the Drivelock system, engineered for exceptional rigidity and a rock-solid lockup.

This design supports confident target transitions, reliable alignment, and a clean, purpose-built feel in the hand.

Thoughtful details throughout the rifle reflect a focus on reliability and ergonomics. Reduced carrier drag raceways promote smooth cycling, deep cable channels help keep accessories organized, and scalloped picatinny slots add a refined, functional touch. Weighing just under six pounds, the MK1 CAR SBR balances nimble handling with the strength and control serious shooters expect from Sons of Liberty Gun Works.
