Davidson Defense Trailhead w/SBA5 Brace 12.5-inch Pistol-Gas 1:10 308 AR-10 M-Lok Pistol Full Build Kit

Trailhead w/SBA5 Brace 12.5-inch .308 Winchester AR-10 Full Build Kit

The Trailhead w/SBA5 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 free-float M-LOK handguard with a muzzle-mounted fake can at the muzzle, running on a pistol-length, direct-impingement 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, carbine buffer-system components, and an SB Tactical SBA5 pistol 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, direct-impingement 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.

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 Mil-Spec heavy-duty six-position buffer tube, holding an LR-308 collapsible stock buffer weighing 3.76 ounces and an AR-10 carbine extra-power recoil 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 an SB Tactical SBA5 pistol stabilizing brace finished in black. It mounts to the six-position buffer tube included with this kit.
