Sons of Liberty Gun Works M4-L89 SBR 5.56 12.5" 30-Round Rifle

The Sons of Liberty Gun Works M4-L89 SBR is built for shooters who expect hard-use reliability in a compact 12.5 inch platform. Chambered in 5.56 with a carbine gas system, it balances quick handling with confident performance, making it a smart choice for demanding range work and serious defensive use. The 11.75 inch L89 Drivelock handguard gives you a secure, rigid foundation with 7-sided MLOK mounting and integral steel QD cups for fast sling attachment. At the core is SOLGW's Liberty Fighting Barrel, designed with a medium contour, 1:7 twist, and .223 Wylde chamber for consistent accuracy and compatibility with .223 Remington and 5.56 NATO. The enhanced A5 buffer system helps soften recoil and improve control, while the Liberty 2-stage trigger offers a crisp, predictable break for better shot placement. A full-featured ambidextrous control setup, including the safety selector and charging handle, supports efficient handling from either side. Finished in anodized black, this SBR pairs premium forged receivers, durable steel components, and a battle-ready profile into one refined, purpose-built firearm.
