The Diamondback DB10 8.6 Blackout pistol puts the 8.6 Blackout cartridge into a 12-inch AR-pattern pistol with an SB Tactical SBA5 brace (brand part no. DB1200W001). Diamondback spins the barrel at a fast 1:3 twist and pairs it with a pistol-length gas system and a Superlative adjustable gas block, so the gun can be tuned for different loads. An 11-inch M-LOK handguard, a Magpul MOE K grip and a 20-round Magpul PMAG complete the build. It is a compact option for shooters who want a short, hard-hitting 8.6 Blackout platform.
