Diamondback DB15 Pistol | 5.56 NATO | 7in | DB1912K001

The Diamondback DB15 is an AR-style pistol built around a 7-inch Black Nitride 4150 Chrome-Moly Vanadium barrel and a pistol-length gas system for compact handling and consistent cycling. Receivers are forged from 7075-T6 aluminum and the bolt carrier group is a shot-peened, MPI-inspected Mil-Spec 8620 carrier for long-term durability. The 6-inch M-LOK handguard accepts accessories without excessive bulk; a low-profile red-dot or reflex optic works well on the A3 flat-top receiver—consider a Holosun HS510C for a durable, low-profile option under $1000 that suits this platform.
