Second focal plane
Where riflescopes have reticles in the second focal plane, the size of the reticle remains constant, regardless of magnification. As a result, the coverage area changes with the chosen magnification.
Non-illuminated reticle
Non-illuminated, fine-structured reticle for precise aiming.
Main tube diameter 36 mm
The main tube has a diameter of 36 mm.
MOA 1/8
Click resolution MOA: 1/8 MOA click corresponds to a point of impact shift of 0.36 cm at a distance of 100 m.
Adjustment direction CCW
The adjustment direction of the elevation and windage turrets is designed to be counter-clockwise (ccw).
Top mounted parallax
The top mounted parallax adjustment sits below the elevation turret. The patented central arrangement allows for simple and intuitive operation of all controls with the preferred hand, without needing to reach over.
Windage right
The windage adjustment is located on the right side.
EASYREAD
Adjustment turrets with EASYREAD labelling provide excellent readability and clear identification under challenging conditions.
REVOLUTION INDICATOR
The REVOLUTION INDICATOR (mechanical) uses the Indicator Pin as a reference: depending on its position, it continuously displays the current revolution level, ensuring a reliable and instantly recognisable position indication.
ZEROSTOP
The ZEROSTOP (mechanical stop) is positioned 2–3 clicks below the zero indicator and is set after sighting in, allowing a quick and repeatable return to zero.
VISIONFLEX
VISIONFLEX creates an exceptionally wide field of view and opens a remarkably generous eyebox, delivering a natural, fatigue-free viewing experience that remains consistent across all magnifications.
