This Diamondback DB15 .300 Blackout OD Green pistol (brand part no. DB1916B101) pairs a 10-inch heavy barrel with a pistol-length gas system and an OD Green Cerakote finish. Diamondback Firearms builds it on a forged Diamondback Carbon lower with a 9-inch M-LOK handguard, a Magpul MOE grip and an SB Tactical SBA3 brace. The .300 Blackout chambering suits short-range work and compact builds, and the short overall length keeps the pistol handy in a vehicle or a truck-gun role. It ships with a 30-round Magpul Gen M3 PMAG, so it is ready for the range once you add your own optic or sights.

Key Specifications

• The chambering is .300 Blackout, a short, efficient cartridge that works well from a 10-inch barrel.
• The barrel is a 10-inch, 1:8 right-hand twist heavy 4150 CrMoV barrel with a black nitride finish, which resists wear and shrugs off heat.
• The gas system is pistol length, tuned to cycle from a short barrel.
• The finish is OD Green Cerakote, a durable coating that sets this pistol apart from the black version.
• The brace is an SB Tactical SBA3, which gives the pistol a stable point of support when it is shot braced against the forearm.
• The handguard is a 9-inch M-LOK rail, so lights, grips and other accessories bolt on directly.
• The upper is an A3 flattop forged 7075-T6 aluminum receiver, which accepts a red dot or magnified optic.
• The bolt carrier is a shot-peened, magnetic particle inspected Mil-Spec 8620 carrier, a quality check that matters on a harder-working short-barrel action.
• The muzzle device is an A2 flash hider on 5/8×24 threads, a common pattern for other muzzle devices.
• The weight is 5.7 pounds with an overall length of 25 3/4 inches, light and short enough to carry and maneuver easily.
