The Diamondback DB10 6mm ARC rifle is a compact, hard-hitting platform built for shooters who want modern ergonomics and proven reliability without compromise. Built on a forged 7075-T6 aluminum receiver with black hard coat anodize finish, this 18-inch mid-length direct impingement rifle delivers the kind of accuracy and control that works equally well on the range, in a hunting situation, or when you need a dependable rifle that handles like it was built for the job. The 6mm ARC cartridge—increasingly popular among precision rifle enthusiasts—offers a real sweet spot between velocity, energy, and recoil, making it an intelligent choice if you want effective performance without the overkill of larger magnums.
The DB10 comes configured for serious users: a 26-round magazine means you're prepared for extended shooting sessions, while the 15-inch M-LOK handguard with integrated Picatinny rails and QD mounts gives you real estate to run optics, lights, or other accessories exactly how you want them. Magpul's MOE K2 grip and CTR carbine stock provide ergonomic control and adjustability, letting you dial in a comfortable shooting position whether you're in a competition setting or working from behind a bag. The mid-length gas system keeps things balanced; the shot-peened, magnetic particle inspected carrier promises durability under demanding use. The DB Obsidian muzzle brake helps manage recoil and keep your sight picture steady.
This is not a tacticool mall ninja build—it's a purposeful rifle for hunters, precision shooters, and anyone serious about 6mm ARC ballistics. No sights come installed, so you'll mount your optic of choice, but the A3 flat-top upper is ready for standard rings and bases. At 6.8 pounds and collapsing to 35 inches, the DB10 stays handy without sacrificing the 18-inch barrel's velocity and reach. If 6mm ARC is your caliber, this is a no-nonsense foundation to build on.

6mm ARC is a modern rifle cartridge designed for accuracy and efficiency. It delivers good velocity and energy in a package that produces less recoil than larger cartridges, making it popular with precision shooters and hunters who value controllability and follow-up shots. It's also compatible with standard AR magazines, as this rifle's 26-round capacity shows.
The DB10 features an A3 flat-top receiver with standard Picatinny rail on top—compatible with any optic rings and bases that fit that interface. Choose based on your intended use: a compact variable scope for hunting, a dot for close-range work, or a higher-magnification optic if you're building a precision rifle.
No, sights are not included. The flat-top upper is designed for you to install your own optic system, giving you full freedom to configure the rifle for your specific needs and budget.
Yes. The CTR carbine stock is adjustable for length of pull, and the MOE K2 grip is ergonomically designed. These Magpul components are standard tools for dialing in your shooting position.
