Diamondback DB15 7" 5.56 NATO AR Pistol – Burnt Bronze Cerakote, Free-Float M-LOK, 30+1
Diamondback’s DB15 Pistol pairs a 7-inch, heavy-profile 4150 CrMoV barrel with a compact, 23-inch overall length, delivering rifle performance in a maneuverable AR-pistol package. A factory Burnt Bronze Cerakote finish covers the forged 7075-T6 aluminum receivers, while a 6-inch free-float M-LOK handguard keeps weight to just 5.1 lb unloaded. The pistol-length gas system, threaded muzzle, and flat-top upper with T-marked Picatinny rail make this recent-release DB15 ready for accessories or a suppressor.

The 7-inch barrel is nitrided inside and out, providing corrosion resistance and extended service life. Its 1:8 RH twist stabilizes a broad range of 5.56 NATO and .223 Remington bullet weights, and the threaded muzzle is ready for flash hiders, brakes, or suppressors.
Forged 7075-T6 upper and lower receivers give the DB15 the strength of a full-size AR-15. Both receivers wear the same Burnt Bronze Cerakote as the handguard, creating a uniform, durable finish and showcasing Diamondback’s shield logos and caliber markings.
A 6-inch free-float M-LOK aluminum handguard offers three inches of uninterrupted Picatinny rail up top and multiple M-LOK slots for lights or grips without adding bulk. The flat-top upper is T-marked for repeatable optic placement, and the multi-cal lower is engraved “CAL. MULTI” for caliber flexibility.
The polymer pistol brace and Magpul MOE pistol grip supply secure handling in a compact form. Weighing just 5.1 lb unloaded, the pistol balances quickly while retaining the capacity of a standard AR—30+1 rounds—included via the Magpul PMAG.
Factory configuration includes a direct-impingement operating system and a pistol-length gas tube optimized for reliable cycling with standard 5.56 ammo.
