Diamondback Firearms DB10 .308 Win Pistol, 13.5″ Barrel, 20+1-Round

Product Description

The Diamondback Firearms DB10 is a semi-auto .308 Win pistol with a 13.5″ barrel. It is built on the AR layout, with a forged 7075 T6 aluminum frame and a black hardcoat anodized finish. Overall length is 30″.

The barrel is 4150 chrome moly with a 1:10″ twist. It runs a direct impingement system with a mid-length gas system. The muzzle is threaded 5/8×24 and wears an A2 flash hider, so you can swap it for another device with the same thread. A manual safety is fitted, and the trigger is a standard one.

Rail, grip and brace

A 13in M-LOK rail runs along the front end. You can mount lights, grips, bipod mounts and other M-LOK accessories where you need them. The A3 flattop receiver has an optic mount. The pistol has no sights, so plan on adding an optic or a set of backup sights. The Magpul MOE K grip and the SBA3 brace come on the gun. One polymer AR-style magazine is included, and it holds 20 rounds, with one more in the chamber.

The DB10 suits shooters who like the AR controls but want a .308 Win chambering. It fits range days, steel work and general testing of a big-bore pistol. Good companions are a quality optic with a mount, a sling, extra AR-style magazines, a weapon light for the M-LOK rail, and a sturdy case sized for a 30″ firearm.
