Durable riflescope from the manufacturer Nikko Stirling, which has more than 60 years of experience in producing optical equipment. Thus, you can definitely count on the high processing quality.
Nikko Stirling riflescopes are made of black anodized aluminum alloy and can even withstand the recoil of spring-piston air rifles with an energy of up to 16J. In addition, they are filled with nitrogen, which prevents the internal optical system from fogging up during sudden temperature changes.
This model provides variable magnification of 4-12x and the 1/2 Mil Dot (HMD) reticle is located in the second focal plane, which means that it does not enlarge as you increase the magnification. The rectification turrets in MOA units (1 click = 1/4 MOA) are enclosed (the caps must be unscrewed in order to adjust the riflescope).
It is also equipped with reticle illumination (marked IR) in either red or green, each with 5 levels of intensity.
The AO marking means that you can adjust the parallax from 9.1m to infinity.
To install the riflescope, it is necessary to purchase mounts for 25.4mm tube.
