Diamondback DB15 AR Pistol 5.56 NATO 7in 6in M-LOK

About this product

The Diamondback DB15 is an AR-style pistol configured for compact handling and reliable function. It features a 7-inch pistol-length barrel with a 6-inch M-LOK handguard for accessory mounting, and forged 7075-T6 aluminum receivers for durability. The platform uses a pistol-length gas system and a shot-peened, magnetic-particle inspected Mil-Spec 8620 bolt carrier group. This configuration is well suited to range use, compact duty, and close-quarters training where a shorter AR platform is preferred.
