Barrel and Gas System

The 16-inch barrel is chambered in 5.56 NATO and constructed from 4150 Chrome Moly Vanadium steel with a medium profile and a 1:7 twist rate. The nitride finish covers the full barrel surface for corrosion and wear resistance. The muzzle is threaded 1/2x28 and includes a GI birdcage flash hider with a manganese phosphate finish. The carbine-length gas system pairs with a micro low-profile gas block at .750 O.D., a separate component positioned beneath the handguard on the barrel.

Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum with an anodized finish and M4 feed ramp compatibility. The Unique-ARs 15-inch Web freefloat handguard provides accessory mounting options along its length without contact with the barrel or gas system components.
