Why the DIAMONDBACK DB-15 stands out

The DIAMONDBACK DB-15 is offered as a Certified Used firearm in the Semi Auto category, giving buyers confidence in condition and serviceability. This specific package is notable for its inclusion of seven 30-round magazines—ideal for extended training or staged defensive roles where reload speed and preparedness matter.

Built for modularity: quad rail handguard

The quad rail handguard on the DIAMONDBACK DB-15 provides real estate for lights, vertical grips, and backup irons. A four-rail system preserves rigid mounting points for accessories, reducing shift under recoil and ensuring repeatable zero when adding lights or lasers for household defense scenarios.

Optics: Trijicon 4×32 ACOG w/ amber chevron

Matched to the DIAMONDBACK DB-15 is a Trijicon 4×32 ACOG optic with an amber chevron reticle. The ACOG’s fixed 4x magnification gives fast target ID at intermediate ranges while the illuminated chevron provides a clear aiming point in varying light. This combination is favored for its ruggedness and simplicity—no batteries required for the primary reticle illumination in many ACOG models—making it a tactical choice for duty or home defense.

The Certified Used designation means the rifle is graded very good to excellent and includes a ‘no questions asked’ return policy for additional buyer assurance.
