The Diamondback DB15 5.56 NATO FDE SBA3 pistol (brand part no. DB1916K061) wraps a 10-inch barrel in Flat Dark Earth Cerakote and adds an SB Tactical SBA3 brace. Diamondback Firearms pairs the medium-profile barrel with a carbine-length gas system on this 5.56 pistol. A 9-inch M-LOK handguard, Magpul MOE grip and a 30-round Magpul PMAG complete the package. It is a good match for shooters who want a compact 5.56 pistol that is quick to mount accessories on.

Key Specifications

• The chambering is 5.56 NATO, a flexible military-pattern cartridge with wide ammunition availability.
• The barrel is a 10-inch, 1:8 right-hand twist, medium-profile 4150 CrMoV with black nitride, a profile that saves weight over the heavy barrels used elsewhere in the line.
• The gas system is carbine length, a different setup from the pistol-length systems on the 7-inch models.
• The finish is Flat Dark Earth Cerakote, a tough, low-gloss coating.
• The brace is an SB Tactical SBA3, supporting the pistol when it is shot braced to the forearm.
• The handguard is a 9-inch M-LOK rail, so lights, lasers and grips mount without extra adapters.
• The upper is a forged 7075-T6 aluminum A3 flattop, ready for an optic.
• The bolt carrier is a shot-peened, magnetic particle inspected Mil-Spec 8620 carrier for long-term durability.
• The muzzle device is an A2 flash hider on 1/2×28 threads, the standard 5.56 thread pattern.
• The weight is 5.7 pounds and the overall length is 25 3/4 inches, compact for a pistol that carries a 30-round magazine.
