The Diamondback DBX pistol in 5.7x28mm with a 20+1 capacity and midnight bronze Cerakote finish (brand part no. DB1614L071) is an AR-pattern large-format pistol built around a dual gas piston system for reliable operation. Diamondback forges the receiver from 7075-T6 aluminum and wraps the 8-inch threaded barrel in a 6061 aluminum M-LOK handguard, with a 1-in-9-inch twist rate matched to 5.7x28mm ballistics. A 2-position thumb safety and a Magpul MOE K grip round out the controls, and the pistol ships with one 20-round magazine. Among AR-pattern semi-auto handguns, this DBX configuration favors shooters who want a large-format 5.7x28mm platform.
