Diamondback DB15 .300 BLK 10″ SBA3 Brace | 30rd | DB1916B061

The Diamondback DB15 Carbon is a compact AR-platform pistol chambered for .300 AAC Blackout, built with forged 7075-T6 receivers and a 9″ M-LOK handguard for accessory flexibility. It uses a pistol-length direct impingement gas system and ships with an SB Tactical SBA3 arm brace and a 30-round Magpul PMAG. The Flat Dark Earth Cerakote finish and threaded 10″ barrel make it suitable for configured short-range applications; consider a Vortex Viper PST Gen II 1-6×24 if you want a magnified optic under $1000 that holds zero on this platform.
