The Sons Of Liberty Gun Works M4-L89 Rifle brings the L89 series philosophy to a refined AR platform built for demanding shooters. Centered around a 16" 5.56 NATO Liberty Fighting Barrel and a 15.25" L89 Drivelock handguard with 7-sided M-LOK slots, this rifle offers excellent rigidity, smooth handling, and generous mounting space for lights, grips, and other accessories. Forged upper and lower receivers, an A2-style muzzle device, and premium internal components round out a balanced, duty-ready configuration.

Thoughtfully equipped with a Liberty 2-stage trigger, A5-length buffer system, Magpul pistol grip, and Magpul stock, the M4-L89 delivers a controllable recoil impulse and comfortable ergonomics for extended range sessions or structured training. Its semi-automatic operation and 30-round magazine capacity make it well suited for general range use, practical competition, and home protection roles where reliability and consistency matter. Sons Of Liberty Gun Works is known for meticulous assembly, individual test-firing, and a focus on long-term durability that shows in every detail of this rifle.
