The Diamondback DB10 handgun in .308 Win is a compact, braced rifle built for shooters who want serious power in a short-barreled platform. This 13.5-inch .308 pistol delivers rifle-caliber performance in a form factor that's maneuverable for tactical use, hunting from tight spaces, or precision shooting where a traditional rifle won't fit. The flat dark earth Cerakote finish gives it a professional, field-ready look while protecting the steel underneath.
Built around a forged aluminum upper and lower receiver (7075 T-6), the DB10 combines mil-spec engineering with quality parts throughout. The barrel is 4150 CrMov with a mil-spec black nitride finish and a 1:10 twist rate, paired with a mid-length gas system for reliable cycling. You get a 13-inch M-LOK rail for mounting optics and accessories, a Magpul MOE K grip for control, and an SB Tactical SBA3 brace that's designed for pistol arm stabilization. The included Magpul Gen M3 PMAG holds 20 rounds, and the muzzle is threaded 5/8x24 so you can add a suppressor or compensator.
This is a shooter's gun: the bolt carrier is shot-peened and magnetic particle inspected, the trigger is standard mil-spec, and the whole rig weighs just 5.1 pounds. Collapsed, it measures 30 inches—compact enough to handle, long enough to shoot straight. No sights are included, so you'll want to mount an optic or set of backup irons to the upper receiver's flat-top.
Whether you're into short-barreled rifle shooting, need a truck gun for hunting, or want a .308 pistol for precision work, the DB10 delivers the performance and durability Diamondback is known for in a format that works where full-length rifles don't.

Yes. The 13.5-inch barrel is threaded 5/8x24, which is standard for .308 rifles, so any suppressor with that thread pitch will work. The A2 flash hider is included; you can remove it and install a suppressor in its place.
The upper receiver is a flat-top (A3) design with a standard Picatinny rail, so you can mount any mil-spec scope, red dot, or backup iron sights directly to it. The 13-inch M-LOK handguard also lets you attach lights, lasers, or other accessories along the rail.
No. The DB10 is sold without factory sights, so you'll need to add an optic or backup iron sights to the upper receiver's flat-top rail.
It ships with one 20-round Magpul Gen M3 PMAG. Standard .308 AR magazines will work, and the Magpul PMAG platform offers plenty of capacity and reliability options from other manufacturers.
