Davidson Defense Trailhead 12.5-inch Pistol-Gas 1:10 308 AR-10 M-Lok Pistol Complete Upper Build

Trailhead 12.5-inch .308 Winchester AR-10 Complete Upper

The Trailhead is built around a 12.5-inch Bear Creek SOCOM barrel chambered in .308 Winchester, finished in Parkerized. It's paired with an LR-308 billet upper receiver machined to the DPMS low-profile pattern. It pairs a 15-inch "Friz" LR-308 low-profile free-float M-LOK handguard with a muzzle-mounted fake can at the muzzle, running on a pistol-length gas system. A Recoil Technologies LR-308 bolt carrier group and LR-308 aluminum charging handle round out the upper, giving the buyer everything needed on the upper side.

Barrel and Gas System

The Bear Creek SOCOM barrel runs 12.5 inches long, chambered in .308 Winchester and built from 4150 chrome moly vanadium steel with a Parkerized finish. 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 standard low-profile adjustable gas block machined from steel with a Melonite finish, sized to an .875-inch journal.

Upper Receiver and Handguard

The upper receiver is a billet unit built to the DPMS low-profile pattern, finished in Type III hardcoat black anodizing and machined without a forward assist. The ejection port door ships assembled. Over the barrel sits a 15-inch "Friz" LR-308 low-profile handguard, a free-float design using an M-LOK attachment system with a full-length Picatinny rail running along its top.

Muzzle Device

Capping the muzzle is a muzzle-mounted fake can chambered for .308, threaded to match the barrel's 5/8x24 pattern, giving the build a suppressor-style appearance without functioning as one.

Bolt Carrier Group and Charging Handle

A Recoil Technologies LR-308 bolt carrier group is included, finished in nitride and listed for use across .308 Winchester, 6.5 Creedmoor, and .243 Winchester. An LR-308 aluminum charging handle rounds out the upper's operating components.
