It pairs a Crest Series 15-inch high-profile LR-308 M-LOK handguard with a .308 flash/sound forwarder at the muzzle, running on a mid-length gas system. A Recoil Technologies LR-308 bolt carrier group, aluminum charging handle, Recoil Technologies .308 Mil-Spec quality AR-10 Lower Parts Kit, buffer-system components, and an Adaptive Tactical EX Performance adjustable stock round out the rest of the rifle.

Barrel and Gas System

The barrel runs 16 inches long, chambered in .308 Winchester and built from 4150 chrome moly vanadium steel with a Parkerized finish and heavy profile. It carries a 1:10 twist rate and a 5/8x24 muzzle thread. Gas cycles back to the action through a mid-length system, running a stainless steel mid-length gas tube and a micro low-profile steel gas block sized to a .750-inch journal.

Upper Receiver and Handguard

The upper receiver is an AR-10 high-profile unit finished in black anodizing, fitted with an AR-15 forward assist assembly and an LR-308 ejection port door assembly. Over the barrel sits a Crest Series 15-inch high-profile LR-308 handguard, using an M-LOK attachment system along its length.

Muzzle Device

Capping the muzzle is a .308 flash/sound forwarder, finished in nitride with a smooth exterior profile. It's designed to direct blast and concussion forward, threading onto the barrel's 5/8x24 pattern and secured with the included 5/8-inch black crush washer.

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 quality 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 buffer spring made from 17-7 stainless steel, made in the USA. A standard AR-15 carbine castle nut and Mil-Spec AR-15/M16 receiver end plate secure the buffer tube assembly to the lower.

Stock

Capping off the rifle is an Adaptive Tactical EX Performance adjustable stock, model AT-02012-B. It slides onto the six-position buffer tube included with this kit, giving the shooter adjustable length-of-pull for the final piece of the build.
