Davidson Defense Trailhead w/Gauntlet Arms Brace 12.5-inch Pistol-Gas 1:10 308 AR-10 Freefloat M-Lok Handguard Pistol Full Build Kit

Trailhead w/Gauntlet Arms Brace 12.5-inch .308 Winchester AR-10 Full Build Kit

The Trailhead w/Gauntlet Arms Brace 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 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, LR-308 aluminum charging handle, Recoil Technologies .308 Mil-Spec AR-10 Lower Parts Kit, pistol-caliber buffer-system components, and a Gauntlet Arms polymer stabilizing brace round out the rest of the build. The lower receiver is not included, leaving the buyer to select and supply that component separately.

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 an .875 standard low-profile adjustable gas block machined from steel with a Melonite finish.

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, using an M-LOK attachment system along its length.

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.

Lower Parts Kit and Buffer System

A Recoil Technologies .308 Mil-Spec AR-10 Lower Parts Kit covers the fire-control and lower-control internals needed once a lower receiver is on hand. Behind it sits a heavy-duty pistol buffer tube for AR-15/AR-style pistols, holding an LR-308 collapsible stock buffer weighing 3.76 ounces and an AR-10 carbine extra-power buffer spring made from 17-7 stainless steel. An AR-15 carbine castle nut and Mil-Spec AR-15/M16 receiver end plate secure the buffer tube assembly to the lower.

Stabilizing Brace

Capping off the rear of the build is a Gauntlet Arms polymer stabilizing brace finished in black. It mounts directly to the pistol buffer tube included with this kit, built specifically for pistol-configured AR platforms like this .308 Winchester build.
