The Diamondback DB15 5.56 NATO pistol is a compact, purpose-built AR-pattern firearm designed for shooters who want a maneuverable platform without sacrificing functionality. Built on forged 7075-T6 aluminum upper and lower receivers, this 10-inch heavy-barrel pistol delivers the accuracy and handling of a modern sporting rifle in a footprint that works equally well for home defense, range work, or truck-mounted readiness. At 5.7 pounds, it's light enough to carry all day but substantial enough to run reliably through the vast majority of 5.56 NATO ammunition.
The 10-inch Diamondback barrel is chrome-lined 4150 CrMoV steel with a 1:8 twist rate and 1/2x28 A2 flash hider—a classic, proven combination for velocity and control in a short-barrel rifle. The carbine-length direct impingement gas system keeps things simple and reliable, while the shot-peened, magnetic-particle-inspected mil-spec bolt carrier group is built to mil-spec standards. The upper receiver is A3 flattop forged aluminum, and the lower is the company's own DB15 carbon lower, both designed to tight tolerances for durability.
Ergonomics are handled with a 9-inch M-LOK handguard for accessory mounting, a Magpul MOE grip for positive control, and an SB Tactical SBA3 brace to stabilize the platform. You'll get a 30-round Magpul Gen M2 PMAG in the box, and the gun ships with no front or rear sights—leaving the A3 upper's Picatinny rail and handguard M-LOK slots open for your optic and light setup. Finished in Flat Dark Earth Cerakote, it's built to work hard and look good doing it.

The gun ships with one Magpul Gen M2 PMAG 30-round magazine in 5.56 NATO. No sights are included, but the A3 flattop upper receiver has a Picatinny rail for mounting an optic, and the 9-inch M-LOK handguard accommodates accessories like lights, laser, or backup iron sights.
Yes. The A3 flattop upper receiver features a Picatinny rail for optic mounting, and the 9-inch M-LOK handguard allows you to mount lights, fore grips, or other accessories. No sights come installed, so you'll have complete freedom to set up the gun for your mission.
The 1:8 twist rate stabilizes a wide range of 5.56 NATO loadings, from lighter 55-grain to heavier 77-grain rounds. The 10-inch length keeps the gun compact and maneuverable while the heavy barrel improves accuracy and sustained-fire performance.
