The Diamondback Vision began in 1989 in a small shop building custom airboats. Our reputation grew as a manufacturer, as did our capabilities and product offerings. We began acquiring the equipment necessary to begin creating our parts in-house.
The DB9R 9mm is a blowback-operated carbine designed for simplicity and reliability. Blowback is the simplest semi-automatic operating system, utilizing the energy from the fired cartridge to cycle without the need for a traditional gas system. It is ideal for cycling lower-powered cartridges and relies on a heavy-weight bolt and spring. This cleaner, low-maintenance design and the reduced muzzle blast of the 9mm cartridge make it an ideal choice for training and recreational shooting.
