Barrel and Muzzle Device

The 16-inch straight profile barrel is chambered in .223 Wylde and constructed from 4150 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 journal 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 a black anodized finish with M4 feed ramps, an ejection port cover installed, and a forward assist installed. The 15-inch freefloat M-LOK handguard features a full-length Picatinny top rail, integrated QD sling mounts, and no anti-rotation tabs, with M-LOK attachment points along the body for accessory mounting. These two components define the exterior structure of the upper assembly on this AR-15 platform.
