Diamondback DB15D 5.56 16in M-LOK | DB1758K061

The Diamondback DB15D is an AR-pattern semi-automatic rifle built on forged 7075-T6 aluminum receivers with a 16-inch medium Chrome Moly barrel finished in black nitride and a 15-inch M-LOK anti-rotation handguard. It ships with Magpul furniture (ACS-L stock and MOE K2+ grip), a CMC single-stage trigger, and a 30-round Gen 2 PMAG. For an optic under $1,000 that complements the DB15D, a Vortex Strike Eagle 1-6×24 provides a versatile, durable option for both close and mid-range work.

Typical applications include range training and practical competition, as well as precision varmint or small-game work where an accurate, lightweight AR-platform rifle is preferred.
