Davidson Defense Suppressor Ready Paragon 16-inch Carbine-Gas 1:3 8.6 BLK AR-10 Freefloat M-Lok Handguard Rifle Complete Upper Build

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

The Paragon is built around a 16-inch barrel chambered in 8.6 Blackout, with a SOCOM profile 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 Crown Series low-profile LR-308 free-float M-LOK 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. It runs on a carbine-length gas system. A Recoil Technologies 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 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 an .875-inch adjustable low-profile gas block machined from steel with a Melonite finish.

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 Crown Series low-profile LR-308 handguard, a free-float design finished in black, using an M-LOK 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 LR-308 bolt carrier group is included, finished in nitride and 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.
