The Diamondback DB10 .308 Win pistol in FDE Cerakote pairs a 13.5-inch barrel with an SB Tactical SBA3 brace in a compact rifle-caliber package (brand part no. DB1222C062). It comes from the DB10 Carbon Series, which Diamondback describes as its entry-level line, built with Magpul furniture and an M-LOK compatible handguard. A mid-length gas system and a black nitride 4150 CrMoV barrel handle the .308 Winchester cartridge, while a Magpul MOE K grip keeps the controls familiar. At 5.1 pounds it makes a handy vehicle gun or range pistol for shooters who want full-power performance without a 16-inch barrel.

Key Specifications

• The chambering is .308 Win, a full-power rifle cartridge delivered in a compact AR-style pistol.
• The barrel measures 13.5 inches in 4150 CrMoV with a black nitride finish, which resists wear and corrosion.
• Rifling is a 1:10 right-hand twist on a medium profile, a rate that suits common .308 bullet weights.
• The pistol stabilizing brace is an SB Tactical SBA3, an adjustable brace that gives a steadier hold for the shooter.
• The finish is Flat Dark Earth Cerakote, a durable coating that sets this version apart from the black and Midnight Bronze builds.
• A 20-round Magpul Gen M3 PMAG is the magazine, a proven polymer design that feeds reliably.
• The handguard is a 13-inch M-LOK rail, which gives plenty of room for lights, grips and other accessories.
• The gas system is mid-length, which smooths the recoil impulse on a 13.5-inch barrel.
• The muzzle device is an A2 flash hider threaded 5/8×24, a common thread that accepts a wide range of muzzle devices.
• Weight is 5.1 pounds, which keeps the pistol manageable for a .308 Win.
