Diamondback DBX57 5.7x28mm 8" 20rd Pistol

The Diamondback DBX57 is a compact 5.7x28mm pistol built around a locked breech, dual gas piston operating system rather than a blowback design. The 8" stainless barrel has a 1:9 twist and is threaded 1/2-28 under a DBX muzzle device. The upper is a monolithic forged aluminum receiver with a black hardcoat anodized finish, and the M-LOK handguard takes lights and grips without adding bulk. It weighs 3 lbs and is only 1.75" wide at the controls, so it packs into a small case or bag.

The DBX57 feeds from FN Five-seveN pattern magazines, and one 20rd magazine is included, so spares are easy to find. Controls are familiar to anyone who runs an AR: a standard AR-15 mil spec trigger, a reversible charging handle and a Magpul MOE K grip. There is a rear Picatinny rail and a rear QD point, and this model has no brace or stock attached. No sights are included, leaving the top rail open for a red dot. Overall length is 15.25", making it a compact option for home defense and range work.
