CMC TRIGGERS AR15 5.56 NATO 7.5in Pistol Length Gas Barrel (CMC-BBL-556-001)

Crafted from high-grade 4150 Chrome Moly Vanadium steel, the CMC Triggers 7.5" SOCOM Profile Barrel delivers exceptional durability and accuracy for your SBR or pistol build. Each barrel undergoes rigorous individual inspection, including air gauging to ensure absolute uniformity with land-and-groove tolerance held to just .0001" from breech to muzzle. The button-rifled design, combined with an 11-degree match crown and M4 feed ramps, guarantees reliable feeding and pinpoint accuracy shot after shot.

The pistol-length gas system ensures consistent cycling in compact platforms, while the 1:7" twist rate stabilizes everything from light varmint rounds to heavy 77-grain match ammunition. The 1/2"-28 threaded muzzle accepts standard AR-15 muzzle devices, and the pre-drilled bottom dimple simplifies gas block installation and alignment. Weighing just 1.02 lbs, the SOCOM profile strikes the perfect balance between maneuverability and rigidity for your firearm.

The H&M Blacknitride+ coating significantly enhances wear resistance, corrosion protection, and lubricity while maintaining dimensional stability. This advanced ferritic nitrocarburizing process extends barrel life and ensures reliable performance in demanding conditions. Please note: This 7.5" barrel is intended for use on a registered SBR, machine gun, or pistol lower receiver. Possession with a non-NFA rifle lower is prohibited - all NFA/ATF rules apply.
