The Diamondback Firearms DBX semi-automatic pistol with an eight-inch barrel chambered for the unique 5.7x28mm round is a prime example of why loyal Diamondback customers continue to come back time and again, year over year. Featuring a frame built from 7075-T6 aerospace-grade aluminum with durable Type III Anodized coating, it can withstand even the harshest corrosive conditions and continue to perform flawlessly. If you're looking for a grade-A personal defense weapon, the DiamondBack DBX, although small with a total length of 15.5 inches, provides all the tactical features you'll need. Featuring a handguard machined from 6061 aluminum with a hard anodized finish, the BDX also sports an M-LOK compatible guard and a full-body Picatinny rail up on top to accommodate your favored accessories. Diamondback Firearms also caps the barrel muzzle with its patented DBX muzzle device and includes a Magpul grip for positive control and accurate shot placement.

The short eight-inch barrel has a right-hand twist 1:9 twist that fosters accuracy even at longer distances of over seventy-five yards or more. Sporting a threaded muzzle of 1/2x28 inches, the DBX can be fitted with a suppressor system when stealth is as important as firepower. With smaller size comes a more lightweight solution, and although the DBX offers big-gun features, it only weighs in at three pounds, which offers optimal all-day carry without tiring. The trigger and fire control system of the Diamondback Firearms DBX is standard AR15 Mil-Spec with a pull weight of around six to nine pounds.

Another unique but effective feature of this DBX pistol from Diamondback Firearms is the 5.7x28mm caliber it fires. With the 5.7x28 cartridge, it's entirely possible to achieve velocities at almost two thousand feet per second, with muzzle energy of over three hundred foot-pounds of terminal power upon impact.

Diamondback Firearms specializes in crafting some of the best rifles, modular AR15 aftermarket parts and accessories, and barrels. This locked-breach dual gas system from Diamondback Firearms is everything avid enthusiasts look for in a tactical pistol.
