Diamondback DB15 300 Blackout 10″ AR Pistol Smoked Bronze
This DB15 is a semi-auto AR pistol chambered in 300 Blackout and finished in Smoked Bronze Cerakote. The bronze covers the forged 7075-T6 upper and lower and the handguard, and the black brace and grip break it up. It weighs 5.7 lbs.
Barrel and gas system
The 10″ heavy barrel is 4150 chrome-moly with a black nitride finish and a 1:8 right-hand twist. It runs a pistol-length direct impingement gas system and ends in an A2 flash hider on 5/8×24 threads.
Handguard, brace and optics
A 9″ M-LOK handguard gives you room for a light or a sling mount. An SB Tactical SBA3 brace sits on the back with a Magpul MOE grip below, and overall length runs 26″ to 28.5″ depending on the brace position. It ships without iron sights, so the Picatinny rail on the A3 flat-top upper is ready for a red dot or other optic.
