Barrel and Muzzle Device

The 16-inch straight profile barrel is chambered in .223 Wylde and constructed from 4150 Chrome Moly Vanadium steel with a black nitride finish. The twist rate is 1:8 and the thread pitch is 1/2x28, which matches the included A2 birdcage flash hider. A black crush washer, a micro low-profile steel gas block at 0.750 diameter, and a carbine-length stainless steel gas tube cover the front end gas configuration on this carbine-length platform.

Upper Receiver and Handguard

The 7075-T6 aluminum upper receiver carries an anodized finish with M4 feed ramps, an ejection port door assembly, and a forward assist. The 15-inch M-LOK Slant-Pro freefloat handguard is a Series A design featuring built-in QD mounts, a flat top rail, a quad rail front section for accessory mounting at the muzzle end, anti-rotation tabs for positive upper receiver interface, and oblong lightening cuts along the handguard body. M-LOK attachment points run along the handguard for accessory mounting across the length of the body. These two components define the exterior structure of the upper assembly on this AR-15 platform.

The USA-made complete AR-15 bolt carrier group is compatible with 5.56 NATO, .223 Remington, .300 AAC Blackout, and .350 Legend. A Mil-Spec AR-15 M4 charging handle is included to complete the upper component set.
