After loosening the screw on top of the adjustment turret, the turret cap can be lifted off. Beneath it is the ZeroStop, recognisable as a round black disc. Ideally, the ZeroStop should be set after zeroing the riflescope. To do this, loosen the three grub screws on the ZeroStop disc (on new riflescopes, the ring is usually already loose). In this state, the disc can be turned to its upper stop without affecting the adjustment. Once the disc reaches the stop position, secure it by tightening the grub screws. The stop is clearly visible in the image between the disc and the scope.
Next, refit the turret in its zero position and secure the central turret screw. The ZeroStop now ensures that, when turned back, the adjustment stops exactly at the previously established zero — the distance at which the riflescope was zeroed.
A ZeroStop is particularly useful for returning quickly and precisely to zero after adjusting the reticle, without the risk of turning too far. This is especially advantageous for hunting and sport shooting at changing distances, as you can rely on your zero and concentrate fully on the target.
