Davidson Defense Suppressor Ready Abeyance 16-inch Carbine-Gas 1:3 8.6 BLK AR-10 KeyMod Rifle Complete Upper Build

Suppressor Ready Abeyance 16-inch 8.6 Blackout AR-10 Complete Upper

The Abeyance is built around a 16-inch BC-10 barrel chambered in 8.6 Blackout, with a SOCOM profile finished in Parkerized. It's paired with an AR-10 high-profile upper receiver finished in black anodizing. It pairs a 15-inch high-profile .308 KeyMod handguard with a threaded M18x1.5 muzzle left bare, giving this build a Suppressor Ready configuration since no muzzle device is installed on that threading. A Recoil Technologies nitride LR-308 bolt carrier group, rated for 8.6 Blackout, and an aluminum LR-308 charging handle round out the upper, giving the buyer everything needed on the upper side.

Barrel and Gas System

The BC-10 barrel runs 16 inches long, chambered in 8.6 Blackout and finished in Parkerized with a SOCOM profile. It carries a 1:3 twist rate, suited to stabilizing the heavy-for-caliber projectiles this chambering runs, along with an M18x1.5 muzzle thread. Gas cycles back to the action through a carbine-length system, running a stainless steel carbine-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 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 15-inch high-profile .308 handguard, the MTK15H308 model, using a KeyMod attachment system along its length.

Suppressor Ready

The barrel is threaded M18x1.5 at the muzzle, but no muzzle device is installed on that threading, which is what makes this build Suppressor Ready. The bare threaded muzzle leaves that end open for the buyer's own suppressor mounting solution.

Bolt Carrier Group and Charging Handle

A Recoil Technologies nitride LR-308 bolt carrier group is included, rated for 8.6 Blackout to match the chambering of this build. An aluminum LR-308 charging handle rounds out the upper's operating components.
