Durable rifle scope from Nikko Stirling, a manufacturer with more than 60 years of experience in producing optical devices. You can definitely rely on the quality of workmanship.
Nikko Stirling rifle scopes are made from black anodised aluminium alloy and withstand the recoil even of break-barrel air rifles up to 16 J. In addition, they are filled with nitrogen, which prevents fogging of the internal optical system during sudden temperature changes.
This model offers variable magnification 4–12x, and the 1/2 Mil Dot (HMD - Half Mil Dot) reticle is placed in the second focal plane, which means it does not increase in size as you zoom in. The adjustment turrets in MOA units (1 click = 1/4 MOA) are capped (you need to unscrew the caps to adjust the scope).
It is also equipped with illumination of the reticle (designation IR) in red or green, each with 5 intensity levels.
The designation AO means that the parallax value can be adjusted from 9.1 m to infinity.
To install the rifle scope, you need to purchase separate mounts for a 25.4 mm tube.
