Barrel and Muzzle Device

The 18-inch spiral fluted HBAR profile barrel is chambered in .223 Wylde and constructed from 416R stainless steel with a stainless finish. The twist rate is 1:8 and the thread pitch is 1/2x28, which matches the included Walker steel flash can and muzzle brake in black oxide. A black 1/2-inch crush washer, a micro low-profile steel gas block at 0.750 diameter, and a mid-length stainless steel gas tube cover the front end gas configuration on this mid-length platform.

Upper Receiver and Handguard

The 7075-T6 aluminum upper receiver carries an anodized finish with M4 feed ramps, a forward assist, and an ejection port door assembly. The 15-inch freefloat M-LOK handguard is black with a partial Picatinny top rail section and 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.
