Diamondback DB1984K101 DB15 Obsidian 5.56 NATO 30+1 11.50" Black Nitride 11" M-LOK Handguard SBA5 Brace Magpul MOE K2 Grip

The Diamondback DB15 Obsidian 5.56 NATO is a modern pistol-caliber rifle platform designed for shooters who demand reliability, modularity, and precision in a compact form factor. Built on the proven AR-pattern operating system, this 11.50" barreled configuration delivers rapid target acquisition and reduced signature in close-quarters environments—ideal for home defense, tactical training, and law enforcement applications. The SBA5 brace provides a stable shooting platform while maintaining the agility required in dynamic scenarios.

The Diamondback DB15 Obsidian features a Chrome Moly Vanadium barrel finished in black nitride for superior corrosion resistance and extended barrel life under high round counts. The DB Obsidian muzzle brake reduces muzzle rise and recoil impulse, keeping the sight picture locked during rapid fire sequences—critical for follow-up accuracy. The 11" M-LOK handguard provides ample real estate for accessories while maintaining a lightweight profile at 6.9 lbs unloaded. Premium components include the Breekarms ambi Warhammer charging handle for both-hands operation, Battlearms enhanced bolt catch for reliability, Magpul MOE K2 grip for ergonomic control, and integrated QD mounts for quick-detach sling attachment. The carbine-length gas system optimizes dwell time with the shorter barrel for consistent cycling.

Law enforcement and civilian operators benefit from this platform's compact dimensions (31.5" overall length) and modularity—the M-LOK interface accepts industry-standard rail accessories, lights, and lasers without proprietary adapters. The threaded barrel accepts suppressors or additional muzzle devices for mission-specific configurations. The 30+1 magazine capacity (5.56 NATO) provides adequate rounds for extended engagements. This rifle suits shooters transitioning from pistol-caliber carbines to 5.56 performance, as well as those seeking a lightweight, controllable rifle for vehicle storage or tactical operations requiring a reduced footprint.
