The Diamondback DB15PC is an AR-style pistol chambered in .300 AAC Blackout, built around a 10-inch heavy 4150 CrMov barrel with a black nitride finish. It uses a pistol-length gas system and a free-float 9-inch M-LOK handguard for accessory mounting while maintaining compact handling. The firearm ships without iron sights and is built on forged 7075 T-6 aluminum upper and lower components with a Magpul MOE grip and a padded buffer-tube foam pad. A Vortex Sparc AR red-dot sight is a suitable optic choice under $1000 to pair with this platform for quick target acquisition.
