Diamondback Firearms Diamond Series DB10 6.5 Creedmoor Semi-Auto Rifle

Product Description

The Diamondback Firearms Diamond Series DB10 is a semi-auto rifle chambered in 6.5 Creedmoor with a 20″ stainless barrel. The barrel has a 1:8″ twist, and the muzzle is threaded 5/8″-24 so you can mount a brake or other device that uses that thread.

The handguard is a 15″ M-LOK anti-rotation rail. That gives you a lot of room to add a sling mount, bipod, light, or other M-LOK parts without changing the rifle. The finish is matte, and the rifle is right-handed with a manual thumb safety.

Optic ready, built for your setup

This rifle has no sights, but it is optic ready. Plan on a scope or red dot that suits how you shoot. A variable-power scope makes sense for longer shots, and a bipod and sling are easy first additions. The Magpul stock is a Carbine style in black, with a Magpul K2+. Overall length runs from 37.25″ to 40.75″.

The DB10 feeds from a 20-round magazine. It suits shooters who like the 6.5 Creedmoor cartridge and want a semi-auto platform with a stainless barrel and a threaded muzzle. It works for range sessions, for hunters who want a self-loader, and for builders who plan to customize with M-LOK accessories.
