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.
