Item # 69595 Style NKK-NMM3940AO Condition New Manufacturer [Nikko Sterling](https://www.kygunco.com/brand/nikko-sterling) Weight 3 lb Hunting 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 Nikko Stirling has 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!
