Diamondback Firearms DB10 .308 Win Pistol, 13.5″ Barrel, 20+1-Round, DB1222C072

Product Description

The Diamondback Firearms DB10 is a .308 Win pistol with a 13.5″ barrel and a 20+1-round capacity. It is a semi-auto built on an AR-style layout, with a forged 7075 T6 aluminum frame and a Midnight Bronze Cerakote finish.

The barrel is 4150 chrome moly with a 1:10″ twist. It is threaded 5/8×24 and wears an A2 flash hider. The gun runs on a direct impingement system with a mid-length gas system. Overall length is 30″. It has a manual safety and a standard trigger.

Rail, brace and grip

A 13in M-LOK rail surrounds the barrel, and an A3 flattop gives you a spot for an optic. The pistol ships without sights, so plan on adding one. The SBA3 brace and Magpul MOE K grip come on the gun. One polymer AR-style magazine is included.

This pistol fits someone who wants .308 Win power in an AR-pattern platform and likes to set it up their own way. Good add-ons include a red dot or magnified optic, a sling, a weapon light or bipod that mounts to M-LOK, and extra AR-style magazines. The 5/8×24 threading also lets you swap in other muzzle devices that use that thread.
