Sons of Liberty Gun Works® M4-76 5.56 NATO/.223 Rem. Semi-automatic AR-15 Rifle
The M4-76 is a fully upgraded AR-15 with premium components front to back to deliver the ultimate shooting experience. It's built around around forged 7075-T6 receivers and a VLTOR A5 buffer system specifically designed for the US Marine Corps, and features a 13.7" 4150 steel barrel with a pinned and welded NOX muzzle device. Not only does the NOX bring the M4-76's barrel up to legal length, it also reduces concussion while controlling flash and muzzle rise.
The Rifle also features Sons of Liberty's own M76 M-LOK handguard, which features their new wedgelock attachment system that keeps the free-floating handguard locked tight against the 4140 steel barrel but. The handguard is machined from high-quality aluminum and hardcoat-anodized in black, and comes with an M-LOK QD sling socket that allows you to position your sling however you want it.
The M4-76 features the Liberty Fighting Trigger, which blends the reliability of mil-spec triggers with the clean break and lighter pull of aftermarket triggers. It features a single-stage pull and breaks clean at 5.5-6 pounds, giving you a higher degree of control with less effort and less grit. Components are coated with nickel PTFE for superior smoothness.
Last but not least, the M4-76 comes outfitted with the rock-solid B5 Systems Bravo stock and Type 23 grip—both are significant upgrades over typical out-of-the-box AR furniture. It all adds up to a Rifle that combines the combat readiness of mil-spec with the superior shootability of a match gun.
