Performance and key components

The DIAMONDBACK DB15 is built around a medium 4150 chrome moly barrel in a 16″ length paired with a mid-length gas system. That combination softens recoil impulse and improves gas timing compared with carbine-length systems, which translates to more predictable follow-up shots and reduced wear on components. The rifle’s shot-peened Mil‑Spec 8620 bolt carrier increases longevity and resistance to stress during high-round-count use.

Caliber, capacity, and practical applications

Chambered in 5.56x45mm NATO with a 30+1 magazine capacity, this configuration suits defensive, training, and general-purpose patrol tasks. The 5.56 NATO round offers manageable recoil, effective terminal performance in common engagement ranges, and widespread ammo availability—making the platform versatile for both range work and duty roles.

Chassis, ergonomics, and control features

Receivers machined from 7075‑T6 aluminum provide a rigid, lightweight backbone. The 15″ slim M‑Lok handguard gives ample accessory mounting real estate while keeping overall weight controlled. Ergonomically, the Magpul MOE‑K2 grip and Magpul CTR stock offer comfortable hand placement and a friction-locking, adjustable cheek weld that reduces wobble under optics and lights.

Cosmetic and functional touches include a Diamondback Gold lower receiver finish paired with black furniture for a low-profile, durable appearance, and a DBSB‑IV flash hider to help manage muzzle signature under rapid strings of fire. Price is $798.99, a competitive entry point for a feature-rich package.
