The NIKKO STIRLING Mountmaster 3-9X40 AO Rifle Scope, Mil-Dot Reticle w/ Rings (NMM3940AO) come with full metal alloy adjustment houses for greater reliability. All Mountmaster scopes are shock tested and nitrogen filled at the factory for fog and waterproofing. Adjustments are to 1/4 of an inch and feature a 4 plex reticle as standard. Additionally all Mountmaster scopes come supplied with 3/8" quick detachable mounts - ideal for mounting on air guns and 22 rifles. The reticle supplied is the popular Mil Dot. This model has 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 features finger adjustable windage and elevation bezels and an attractive matte finish. The 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.
