Diamondback DB15 .300 Blackout: Precision Firearm with 16″ Barrel

The modern patrol rifle needs to balance reliability, controllability, and modularity. Whether preparing for close-quarters work or suppressed precision shots, a platform that starts with a solid factory spec and leaves room for mission-specific upgrades is essential.

Design and key features

The DIAMONDBACK DB15 arrives configured for serious use: a 16″ barrel finished with threading for muzzle devices or suppressors, OD Green stock and furniture for low-visibility field use, and a 30+1 round capacity that gives extended on-station endurance. Built by Diamondback, the platform is familiar to AR-style operators and offers a straightforward baseline for optics, rails, and accessory integration.

Ballistics and applications of .300 Blackout

The .300 Blackout chambering gives the DIAMONDBACK DB15 versatility across roles. Subsonic loads are ideal when paired with the threaded barrel and suppressor for quieter CQB or surveillance tasks, while supersonic rounds extend effective terminal performance at medium ranges. For teams and individuals who want a single rifle that performs both suppressed and unsuppressed without heavy reconfiguration, .300 Blackout is a practical choice.

Handling and ergonomics

At a 16″ barrel length, the balance favors maneuverability without sacrificing velocity for typical .300 Blackout loadings. The OD Green stock is comfortable for rapid transitions, and the threaded muzzle reduces barriers to adding compensators or quick-attach suppressors for mission-specific control improvements.

Confirm local compliance and accessory needs before purchase. Check current availability on the product page where the retailer presents purchase options and shipping details.
