PRODUCT DESCRIPTION

Machine translated

In 2016, Nikko Stirling celebrated 60 years of existence. This fact proves one thing, it is no newcomer to the optics market. They developed the Mountmaster line to meet the needs of beginning shooters and offer riflescopes at affordable prices for all.

The riflescopes are filled with nitrogen to prevent fogging. In addition, all models come with a two-piece mount with an 11mm rail mount

Magnification 3 - 9 is the most popular among shooters and is sufficient for shooting at around 30 yards.

The AO models have an adjustable parallax, which is used to sharpen the image at different distances.

The turrets are capped and this means you have to manually unscrew the caps before you can use them.

  • Nice picture, the unlit cross is clearly visible even at dusk, I use it at a distance of 30m
  • The basic reference mark for zeroing is not marked on the chimney from the factory, it is necessary to mark it with a marker...
