Description

The Carbon DB15 Pistol is Diamondback’s compact, AR-pattern pistol built on the same Carbon Series architecture as the company’s entry-level rifles: forged 7075-T6 upper and lower receivers with an A3 flattop for optics mounting, run on a pistol-length gas system. The 10″ barrel is 4150 chrome-moly-vanadium steel in a heavy contour with a black nitride finish and a 1:8″ RH twist, fast enough to stabilize heavier subsonic .300 Blackout loads alongside supersonic ammunition. The muzzle is threaded 5/8×24 and ships with an A2 flash hider.

A 9″ M-LOK handguard leaves room for lights and grips without extending past the gas system. Furniture is Magpul: an MOE pistol grip paired with an SB Tactical SBA3 arm brace for a stable single-hand or braced hold. The bolt carrier group is a shot-peened, magnetic-particle-inspected mil-spec 8620 carrier behind a standard mil-spec trigger. A 2-position thumb safety is fitted, and the pistol ships with no sights, leaving the flattop rail open for the buyer’s optic of choice. Includes one 30-round Magpul Gen M3 PMAG. Built by Diamondback in Cocoa, Florida.
