The Diamondback DB15 is a semi-automatic rifle chambered in .223 Rem / 5.56 NATO with a 16-inch KAC cold hammer forged barrel and 15-inch M-LOK anti-rotation rail. The rifle is built on forged 7075-T6 aluminum receivers and incorporates a carbine-length gas system with a pinned low-profile gas block.
The 16-inch medium-profile barrel is constructed from 4150 Chrome Moly steel and finished in black Melonite for corrosion resistance. A 15-inch free-float M-LOK handguard accommodates AR-15 accessories including foregrips, lights, and bipods. The flat-top upper receiver is optic-ready for custom sight mounting.
Standard equipment includes a Magpul MOE grip, adjustable Magpul Carbine stock (CTR), a 30-round PMAG capacity magazine, Magpul MBUS sights, and a Diamondback plastic case. Diamondback Firearms manufactures the DB15 entirely in the USA, utilizing the U.S. Military-proven gas-impingement system and components produced in Diamondback’s CNC facility.
