The Sons of Liberty Gun Works M4-L89 is a top-tier, duty-grade rifle optimized for suppressor use and long-term durability. Unlike the SBR version, this model is a standard Complete Rifle because the Huxwrx Flash Hider is Pin and Welded (P & W) to the 14.5-inch barrel, bringing the permanent length to over 16 inches and avoiding NFA restrictions. It features the robust L89 Drivelock handguard, known for its exceptional rigidity and thermal management, and utilizes the A5 Buffer System to provide a smoother, more reliable recoil impulse. Finished in a mil-spec hard-coat anodized black, this rifle is built to exceed professional requirements for accuracy and reliability.
