The Mountmaster 4x32 AO by Nikko Stirling offers you a decent rifle scope which possesses some notable features. This rifle scope is provided with a 32 mm objective, a magnification of four times and an eye relief distance of 85 mm to the eyepiece. This makes the FOV (Field Of View) 9.8 m at 100 m. Furthermore, the eyepiece features a special ring with which you can focus fast and easily.
The matte black casing is made of an aluminium alloy that is 1 inch (25.4 mm) in diameter and provides a waterproof and shockproof product. Internally the rifle scope is filled with nitrogen, this prevents the lenses from fogging when there’s a temperature change.
The HMD reticle of the Nikko Stirling Mountmaster 4x32 AO is adjustable in steps of ¼ MOA in both elevation and windage. These adjustments have a range of 80 MOA. On top of that, you can also adjust the parallax from 9 m (10 yards) to infinity.
The rifle scope has multicoated lenses which offer a clear and crisp image and is available in two different versions:
- IR model that features an illuminated reticle in red/green
- Standard, non-illuminated model
The rifle scope includes a ⅜” scope mount.
