Barrel and Gas System

The 18-inch barrel is machined from 4150 chrome moly vanadium steel in a contour profile with a Manganese Phosphate finish and a 1:10 twist rate suited to .308 Winchester. It runs a mid-length gas system through a stainless steel gas tube and a micro low-profile steel gas block with a .750-inch diameter. At the muzzle, 5/8x24 threads carry the included AR-10/.308 Long Super Compensator muzzle brake, secured with the supplied 5/8-inch black crush washer.

Upper Receiver and Handguard

The upper receiver is a billet LR-308 unit built to the DPMS low profile pattern with a Type III hardcoat black anodized finish, and the ejection port door ships assembled. This upper is in a slick-side configuration, meaning the forward assist is not included. It's paired with a 17-inch low-profile, free-float M-LOK handguard.

Bolt Carrier Group and Charging Handle

A Recoil Technologies bolt carrier group is included, finished in Nitride for corrosion resistance and smoother cycling, and rated across .308 Winchester, 6.5 Creedmoor, and .243 Winchester. Alongside it, an aluminum LR-308 charging handle is included, sized correctly for the AR-10 pattern upper.
