The DB15 is an AR-15 platform rifle chambered in 5.56mm NATO and built on Diamondback receivers marked with the DB shield logo and "CAL. MULTI" on the lower. It runs a direct impingement system and feeds from standard 30-round magazines for a 30+1 capacity. Made in the United States, it offers familiar AR ergonomics with purposeful feature choices.
The 16-inch barrel is threaded and capped with an A2-pattern flash hider. A long, free-float aluminum M-LOK handguard provides modern attachment real estate and includes partial top rail sections. The upper receiver carries a flat-top, T-marked Picatinny rail with forward assist and a case deflector. The ejection-port cover is marked "5.56 NATO."
Furniture is configured for practical handling: a collapsible polymer stock with a rubberized buttpad and a Magpul MOE pistol grip, both in FDE, match the Flat Dark Earth finish of the receivers and handguard. An ambidextrous safety selector supports versatile control, and the listed length of pull is 10.5 inches.
Useful additions are already installed: a B5 vertical foregrip and an M-LOK QD sling mount with QD swivel. The rifle ships without sights and includes a 30-round Magpul PMAG polymer magazine.
