Diamondback DB15 300 Blackout 10″ AR Pistol FDE
This DB15 is a semi-auto AR pistol chambered in 300 Blackout. The forged 7075-T6 upper and lower and the handguard are finished in Flat Dark Earth Cerakote, with a black brace and grip for contrast. 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 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. It ships without iron sights, so the Picatinny rail on the A3 flat-top upper is ready for a red dot or other optic.
