Product Description


SII Big Sky 36x42mm Matte Black Dot Scope

Sightron has introduced a 36 power rifle scope that is sure to catch the eye of avid benchrest target shooters. The new addition to the SII Big Sky line of scopes has several features that serious benchrest shooters look for in a quality scope.

Like all Sightron rifle scopes, the new 36x42mm scope is built around a one-piece mono-tube. The tube is the perfect platform for a large scope, giving it strength and durability. The glass lenses of all the SII Big Sky scopes are precision ground and hand-fitted in the scope. Outside lens surfaces are multi-coated with Zact-7, Revcoat with Climate Control Coating. These lenses will enable the shooters to see clearly in all types of weather, including rain. The SII Big Sky 36x42mm scope uses Sightron's enhanced ExacTrack adjustment system with 1/8 MOA target knobs. By loosening 3 set screws on the turret, the scope can be reset to zero. The scope also incorporates a 1/8 MOA dot reticle. This scope has an adjustable objective and this complete system is proving to be a winning combination.
