Diamondback DB15 Obsidian | 5.56 NATO | 16″ | DB1784K061

The Diamondback DB15 Obsidian is a U.S.-made AR-style semi-automatic rifle chambered in .223 Rem/5.56 NATO that pairs modern materials with a feature-rich parts kit. It uses a 16″ Diamondback 4150 Chrome-Moly-Vanadium barrel with a 1:8″ rate of twist and a mid-length gas system for a balanced recoil impulse. The rifle comes fitted with a 15″ anti-rotation M-LOK handguard, ambidextrous controls, Magpul MOE K2 grip and Magpul CTR stock, and includes a 30-round Magpul PMAG. For a matched optic under $1,000 consider a Vortex Strike Eagle 1-6×24 for versatile close-to-mid range use.
