The twist rate is 1:7 and the thread pitch is 1/2x28, which matches the included Crown muzzle brake in nitride finish. A black crush washer, a micro low-profile 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.

The upper receiver is 7075-T6 aluminum with an anodized finish, M4 feed ramps, an AR-15 style ejection port cover, and a forward assist. The 10-inch ACE-20 Series freefloat M-LOK handguard provides M-LOK attachment points along the rail body for accessory mounting. These two components define the exterior structure of the upper assembly on this AR-15 platform.
