Diamondback DB15 5.56 Pistol 7" Barrel FDE

Diamondback DB15 5.56 Pistol

The Diamondback DB15 is a purpose-built 5.56 NATO pistol designed for shooters who demand compact size without compromising reliability or ergonomics.

Barrel and Gas System

The rifle features a 7-inch heavy 4150 Chrome Molybdenum Vanadium barrel with Black Nitride finish, paired with a pistol-length Direct Impingement gas system. This combination delivers reliable operation in a compact package while the heavy profile barrel resists heat distortion during extended shooting sessions. An A2 flash hider (1/2 x 28) manages muzzle blast.

Receiver and Build Quality

Both upper and lower receivers are forged from 7075-T6 aluminum with T-markings on the upper. The bolt carrier group features shot-peened, magnetic particle inspected Mil-Spec 8620 construction—the same standard used in military rifles. This attention to detail ensures durability and consistent performance.

Ergonomics and Controls

The 6-inch M-LOK handguard provides mounting flexibility for accessories while keeping the overall profile compact. A Magpul MOE grip offers comfortable control, and the SB Tactical SBA3 brace stabilizes the pistol for accurate shooting. Standard Mil-Spec trigger provides predictable break.
