Watchtower 18-inch 6.5 Creedmoor AR-10 Full Build Kit w/Plan B Trident Flash Hider

The Watchtower is a Full Build Kit built around an 18-inch HBAR 6.5 Creedmoor barrel with straight flutes, finished in Melonite, paired with an LR-308 billet upper receiver machined to the DPMS low-profile pattern and finished in Type III black hardcoat anodizing. It pairs a Swift Series 17-inch low-profile free-float M-LOK handguard with a Delta Team Tactical Plan B Trident flash hider at the muzzle, running on a rifle-length gas system. A Recoil Technologies LR-308 bolt carrier group, aluminum charging handle, Recoil Technologies .308 Lower Parts Kit, carbine buffer-system components, and an Adaptive Tactical EX Performance adjustable stock round out the rest of the rifle. The lower receiver is not included, leaving the buyer to select and supply that component separately.

Barrel and Gas System

The barrel runs 18 inches long, chambered in 6.5 Creedmoor with an HBAR profile, cut with straight flutes and finished in Melonite. It carries a 1:8 twist rate and a 5/8x24 muzzle thread. Gas cycles back to the action through a rifle-length system, running a stainless steel rifle-length gas tube and a standard low-profile adjustable gas block sized to a .936-inch diameter and finished in Melonite.

Upper Receiver and Handguard

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 Swift Series 17-inch handguard, free-floated in a low-profile design using an M-LOK attachment system along its length.

Muzzle Device

Capping the muzzle is a Delta Team Tactical Plan B Trident flash hider, machined from 17-4 stainless steel, heat-treated to the H1150 condition and finished in nitride, built in a three-prong design with a Plan B-style suppressor mounting interface. It threads onto the barrel's 5/8x24 pattern.

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 charging handle, machined from aluminum, rounds out the upper's operating components.

Lower Parts Kit and Buffer System

A Recoil Technologies .308 Mil-Spec quality Lower Parts Kit, built for the AR-10/LR-308 platform, 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 carbine 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 in the USA. An 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, finished in black, adjusting across multiple positions. It's built for a Mil-Spec carbine buffer tube, matching the buffer tube included with this kit.
