DIAMOND FIREARMS BACK DB10 8.6 BLACKOUT SEMI-AUTO PISTOL
Engineered for shooters who demand power in a compact platform, the Diamondback DB10 in 8.6 Blackout delivers serious subsonic and suppressed-ready performance in a maneuverable AR pistol configuration. Built around Diamondback’s proven DB10 large-frame architecture, this platform is purpose-designed to maximize ballistic efficiency from a short barrel while maintaining durability and control.
At the heart of the system is a 12-inch, 1:3 twist barrel, optimized specifically for 8.6 Blackout projectiles and finished in black nitride for corrosion resistance and extended service life. A pistol-length direct-impingement gas system paired with a Superlative Arms adjustable gas block allows the shooter to fine-tune operation for a wide range of loads and suppressor setups.
The 11-inch V3 M-LOK Anti-Rotation S-Rail provides a rigid mounting platform with full Picatinny top rail and integrated QD sling points, giving ample room for optics and accessories without unnecessary bulk. Forged 7075-T6 aluminum upper and lower receivers ensure strength where it matters most, while the shot-peened, MPI-inspected bolt carrier group delivers reliable cycling under demanding conditions.
Finished in black hardcoat anodizing and equipped with a Magpul MOE-K grip and SB Tactical SBA5 brace, the DB10 balances recoil control, ergonomics, and compact handling. Whether configured for duty use, range performance, or suppressed applications, this pistol offers a refined blend of precision engineering and practical firepower.
