## Description

Product description          Nikko Stirling MountMaster SeriesIdeal for airguns and .22 riflesThese well made competitively priced scopes will stand up to real use. MOUNTMASTER riflescopes come with full metal alloy adjustment houses for greater reliability. Adjustments are to 1/4 of an inch and feature a 4 plex reticle as standard. All MOUNTMASTER scopes are shock tested and nitrogen filled at the factory for fog and waterproofing. Additionally all MOUNTMASTER scopes come supplied with 3/8”quick detachable mounts - ideal for mounting on air guns and 22 rifles.Mountmaster AO seriesHunting small game with airguns or .22 rifles is becoming increasingly popular and a challenging sport. So too are the various plinking targets available today. Usually the game or target is small and the distances can vary from shot to shot. Normally a riflescope is focuses and parallax free at 100 yards. However when the game or target is at closer ranges then focusing and parallax correction is necessary to avoid inaccuracy.The new Mountmater AO series has been developed to provide a fast correction to focus and parallax through the adjustable objective (AO) lenses. Now you can adjust right down to targets that are only 10 yards if required!The AO series feature a very strong 3/8-inch dovetail mount ring. Additionally we have added a recoil stop screw that allows the mount to be secured to powerful airguns without fear of shifting under the sharp recoil of the spring release.The mountmaster AO series features finger adjustable windage and elevation bezels and an attractive matte finish. The reticle supplied is the popular Mil Dot which allows convenient holdover markers allowing quick shooting over varying distances!

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    A well made sight and the AO compensation works very well.
  

*by T***S on Reviewed in the United Kingdom on 11 January 2017*

Nice clear, bright sight. I also tried the 4-12x50 AO but this was quite a lot bigger and quite unnecessary for an air rifle and the 3-9x40 AO is more than adequate for the closer ranges. I really like the fact the sight can be zeroed using Mk-1 fingers (no messing around with coins or screwdrivers) and the parallax compensation works really. Mounted on my trusty HW77K it's a good anti-rat combination at 20 yds.
