Barrel and Gas System

The Bear Creek barrel runs 12.5 inches long, chambered in .308 Winchester and built from 4150 chrome moly vanadium steel with a Parkerized finish and SOCOM profile. It carries a 1:10 twist rate and a 5/8x24 muzzle thread. Gas cycles back to the action through a pistol-length system, running a pistol-length gas tube and a .875-inch low-profile adjustable gas block finished in Melonite.

The upper receiver is an LR-308 billet unit, machined to the DPMS low-profile pattern and finished in Type III black hardcoat anodizing, built without a forward assist. The ejection port door comes included and assembled. Over the barrel sits a Guntec 12-inch handguard, free-floated in an ultra-lightweight, thin design using an M-LOK attachment system with a monolithic Picatinny top rail running along the top.

Muzzle Device

Capping the muzzle is a GI birdcage flash hider, listed as compatible with .308 Winchester, 7.62x39, and .300 Blackout. It threads onto the barrel's 5/8x24 pattern and is secured with the included 5/8-inch black crush washer.
