Barrel and Gas System

This upper uses a 12.5 inch barrel made from 4150 Chrome Moly Vanadium Steel with a Parkerized finish and a SOCOM profile, manufactured by Bear Creek. The 1:10 twist rate is suited to a wide range of .308 Winchester bullet weights, and the 5/8x24 thread pitch matches the included muzzle mounted fake can, built for .308 caliber. A pistol length gas tube runs to a standard low profile adjustable gas block made from steel with a Melonite finish. The barrel and gas components make up the front end of this complete upper.

Upper Receiver and Handguard

The upper receiver is a DPMS low profile billet design finished in Type III hardcoat black anodize. This upper does not include a forward assist, and the ejection port door is included as part of the receiver. The Friz 15 inch low profile freefloat handguard uses M-LOK mounting along with a full length Picatinny top rail, surrounding the barrel without contacting it to give this upper a slim exterior forend built for a pistol length platform.

Bolt Carrier Group and Charging Handle

The included bolt carrier group is a Recoil Technologies LR-308 unit finished in Nitride, compatible with .308 Winchester, 6.5 Creedmoor, and .243 Winchester. An LR-308 aluminum charging handle completes the cycling components of this upper, rounding out the included hardware.
