First focal plane
Where riflescopes have reticles in the first focal plane, the size of the reticle remains proportional to the target and adjusts with the magnification. This allows for precise aiming points and reliable distance measurement, regardless of the chosen magnification.
Illuminated reticle
Illuminated, fine-structured reticle for precise aiming and optimal visibility.
Main tube diameter 36 mm
The main tube has a diameter of 36 mm.
10MIL per revolution turrets
The elevation and windage adjustments with 100 clicks per full revolution allow for fast and precise adjustments under demanding conditions. Enlarged click intervals and clear EASYREAD labelling ensure excellent tactile feedback and secure operation.
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 left or right
Models featuring parallax adjustment integrated into the elevation turret offer ergonomic and intuitive access to all controls. This innovative design allows the windage adjustment to be positioned on either side of the turret housing – left for right-handed shooters and right for left-handed shooters. Thus adjustments can be made without ever leaving the shooting position.
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.
TWISTGUARD
The patented anti-rotation mechanism of the windage turret prevents unintentional adjustments by means of a freely rotating protective cap – without additional locking mechanisms, it is immediately ready for use.
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.
