Diamondback DB15 5.56 NATO

The Diamondback DB15 is an AR-style semi-automatic rifle built around a 16-inch chromoly barrel and designed for range use, training, and general-purpose shooting. This CA-compliant configuration pairs a durable forged receiver set with Magpul controls and a 15" M-LOK handguard for accessory compatibility and comfortable handling.

Built with forged 7075-T6 aluminum upper and lower receivers and a 4150 chromoly barrel finished in black nitride, the DB15 balances durability and everyday practicality. Ergonomics are addressed through a Magpul CTR adjustable stock and a Magpul MOE-K2 polymer grip, while a Gen M3 PMAG 10-round magazine and a Diamondback CNC flash hider are included in the configuration.
