Maven RS4.2 5–30×56 MOA-2 FFP Riflescope

The Maven RS4.2 5–30×56 FFP builds on the original RS.4 with upgraded controls for competitive shooting, precision applications and long-range hunting.

Its premium Japanese ED glass, 56 mm objective lens and approximately 91.84% light transmission provide a bright, detailed image with excellent contrast and accurate colour reproduction.

The first-focal-plane reticle changes size with the magnification, keeping its measurements accurate throughout the complete 5–30× range. Four reticle choices are available across matching MOA and MRAD configurations.

A three-revolution locking elevation turret provides extensive adjustment while helping prevent accidental movement. The capped windage turret protects the windage setting, while a tool-free mechanical zero stop provides a fast and repeatable return to the rifle’s original zero.

The etched-glass reticle offers four red and four green illumination levels. An automatic shut-off function helps preserve battery life.
