A great sight for use with air pistol, .22 rifle and pistol

This compact and lightweight electro sight is built with a more visible easier to center circle dot illuminated in red for quick action plinking. Great for use on .22 or air pistols, .22 rifles, air rifles and some crossbow pistols with dovetail scope mount. Illumination intensity has 11-level adjustments. Fully adjustable for windage and elevation. Durable aluminum alloy tube has anodized matte black finish. Included with the sight is a pair of 30mm rings with a built-in stop pin that can be activated when needed for use on spring piston air pistols or rifles for better resistance against recoil. The rings can also be used with other 30mm tube scopes for mounting onto 3/8inch dovetails typically seen on .22 rimfire rifles, air rifles and some of the crossbows.
