Davidson Defense Incursion SBR Ready 12.5-inch Pistol-Gas 1:10 .308 Win AR-10 M-Lok Pistol Full Build Kit

Incursion SBR Ready 12.5-inch .308 Win AR-10 Full Build Kit

The Incursion SBR Ready Full Build Kit is built around a Bear Creek 12.5-inch .308 Winchester barrel with a SOCOM profile, built from 4150 chrome moly vanadium steel and finished in Parkerized, 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 Guntec 12-inch ultra-lightweight thin M-LOK handguard with a GI birdcage flash hider at the muzzle, running on a pistol-length gas system. A Recoil Technologies LR-308 bolt carrier group, aluminum charging handle, Recoil Technologies .308 Lower Parts Kit, and carbine buffer-system components are all included. The lower receiver is not included, and this SBR Ready version ships without a brace.

Barrel and Gas System

The Bear Creek barrel runs 12.5 inches long, chambered in .308 Winchester and built from 4150 chrome moly vanadium steel with a Parkerized finish and SOCOM profile. 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 .875-inch low-profile adjustable gas block 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 Guntec 12-inch handguard, free-floated in an ultra-lightweight, thin design using an M-LOK attachment system with a monolithic Picatinny top rail running along the top.

Muzzle Device

Capping the muzzle is a GI birdcage flash hider, listed as compatible with .308 Winchester, 7.62x39, and .300 Blackout. It threads onto the barrel's 5/8x24 pattern and is 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. That broader listing describes the BCG itself; the barrel and chambering on this build remain .308 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.
