PR-04 Picatinny Rail for RDM-03
PR-04 Picatinny Rail for RDM-03 is a precision-engineered SMAI-mounted riser rail designed to raise red dot optics to 57 mm or 74 mm while retaining the original RDM mounting system.

The DAVIKA PR-04 Picatinny Rail is a modular height-adjustment solution developed specifically for use with the RDM-03 tactical riser. It allows shooters to elevate their red dot optic to the required optical axis height without replacing the base red dot mount.

Mounted via the SMAI (Scope Mount Accessory Interface), the PR-04 creates a rigid, repeatable, and recoil-resistant platform for red dot optics and subsequent magnifier use. This approach preserves the ergonomics and familiarity of the standard red dot mount while enabling modern shooting configurations.

The PR-04 is ideal for shooters who need to:

align red dots with magnifiers,
raise the optic for night vision compatibility,
or achieve modern 57 mm / 74 mm sight height standards.
Installed on the front SMAI interface of the RDM system, the PR-04 ensures precise positioning and consistent return to zero after removal. Manufactured from 7075-T6 aluminum and compliant with NATO STANAG 4694, it is built for professional and duty-grade use.
