The Diamondback DB10 .308 Win is a modern, versatile AR-pattern rifle built on a forged 7075-T6 aluminum receiver with hard-coat anodized finish—the kind of platform that handles everything from precision range sessions to hunting medium and large game. If you're looking for a .308 Winchester AR that doesn't cut corners on receiver quality or component selection, this rifle delivers the balance of reliability and shootability that working hunters and serious marksmen expect.
The heart of this .308 is a 20-inch medium-profile barrel machined from 4150 CrMoV steel and finished in black nitride, paired with a rifle-length gas system and Superlative Adjustable Gas Block for smooth, reliable cycling under various conditions. The bolt carrier is shot-peened and magnetically particle-inspected to mil-spec standards, ensuring the kind of durability you need when you're counting on your rifle in the field or at distance. Upper and lower receivers are both forged aluminum—no MIM shortcuts—with the upper featuring an A3 flattop and T-marking for classic, proven ergonomics.
Setup out of the box is practical: you get a 15-inch M-LOK handguard for mounting lights, bipods, or other gear; a Magpul MOE K grip for control and comfort; a Magpul MOE Carbine stock for adjustability; and a Magpul Gen M3 20-round PMAG. No iron sights are included, leaving your rail real estate free for your choice of optic. The rifle ships with a thread protector on the muzzle (5/8 x 24 pattern) if you want to add a suppressor or brake down the road. Trigger is standard mil-spec—solid and predictable, not fancy. Total weight comes in at 8.76 pounds, and the collapsed length is 36.50 inches, extending to 39.75 inches with the stock fully extended.
This is a rifle built to work: no proprietary parts, quality aluminum forgings throughout, and components proven across thousands of ARs. Whether you're setting up a .308 for precision rifle matches, hunting expeditions, or a dependable long-range system, the Diamondback DB10 gives you the foundation to do it right.

The rifle ships with an A3 flattop upper receiver with Picatinny rail, so you can mount any standard optic—scope, red dot, or magnified optic—using appropriate rings or direct-attach solutions. No sights are included, so you have full flexibility in choosing your optic setup.
Yes. The muzzle is threaded 5/8 x 24, which is a standard pattern for .308 suppressors and muzzle devices. You'll need to unscrew the included thread protector and install your suppressor or brake of choice.
The DB10 uses forged aluminum upper and lower receivers (not cast or MIM), a 4150 CrMoV barrel with black nitride finish, and a magnetically particle-inspected bolt carrier. The combination of proven components—forged receivers, quality barrel steel, an adjustable gas block, and mil-spec internals—gives you reliability without proprietary parts that complicate building or repairs.
It includes the magazine and a thread protector, but no optic or sights. You'll need to add an optic (mounted to the flattop rail) and ammunition before you can shoot. The standard mil-spec trigger is functional and consistent.
