Diamondback Firearms DB15CCB V2 5.56 NATO Semi-Auto Rifle, 16″ Barrel

Product Description

The Diamondback Firearms DB15CCB V2 is a 5.56 NATO semi-auto rifle with a 16″ barrel. The barrel is 4150 Chrome Moly with a 1:8″ twist. It runs on a direct impingement system with a carbine-length gas system, and the finish is black anodized hard coat.

This rifle ships with no sights. It has an integral Picatinny optic mount at 0 MOA, so you can mount a red dot or a magnified optic and go from there. A quad rail sits around the barrel for accessories. The barrel is threaded and wears an A2 flash hider, which gives you a starting point if you want to change the muzzle later.

Controls and Handling

The DB15CCB V2 has a mil-spec trigger, a manual safety, a forward assist and a dust cover. The stock is a WS A2-style stock, and the grip is A2-style. Overall length is 32.5″. One metal AR-style magazine is included, and the rifle holds 30+1 rounds.

This rifle suits range shooters and carbine builders who like a familiar AR layout and want to pick their own optic. Good gear to pair with it includes a red dot or low-power scope, a sling, a set of extra metal AR magazines, and a case for transport. Add a light or a vertical grip to the quad rail if you want them. Stock up on 5.56 NATO ammunition to match the chambering.
