Sons of Liberty Gun Works M4-L89 5.56mm 12.5" Bbl Carbine Gas L89 Rail A2 FH Brace M4-L89 Anodized Black Complete Pistol M4-L89-556-125-PISTOL-A-BLK

The Sons of Liberty Gun Works M4-L89 is a duty-grade AR-15 pistol featuring a 12.5-inch barrel, which many professionals consider the ideal compromise between the compactness of a short-barreled platform and the superior ballistics of a mid-length system. Built with the L89 Drivelock handguard, this pistol offers a rigid, non-rotating rail system that ensures secondary aiming devices like lasers and iron sights maintain a precise zero. Like other L89 models, it utilizes the A5 Buffer System to provide a significantly smoother recoil impulse and increased reliability across various 5.56 NATO loads. The 12.5-inch barrel length specifically offers increased muzzle velocity and a longer dwell time compared to the 11.5-inch variant, making it a highly versatile choice for both close-quarters and mid-range engagements.
