Diamondback DB9R 9mm 16″ 32rd 15″ M-LOK Black

The Diamondback DB9R is an AR-style 9mm carbine built for practical range use and general-purpose applications. It features a 16-inch 4150 CrMoV barrel with a black nitride finish and a blowback-operated semi-automatic action. The rifle uses forged 7075 T-6 aluminum upper and lower receivers, a 15-inch M-LOK handguard and Magpul MOE furniture for familiar AR ergonomics.
