Only from Monstrum Tactical, the Ruger 10/22 Rifle Scope Ring Set is a dedicated scope mounting platform built specifically for the Ruger 10/22. Each scope ring base installs directly to the Ruger 10/22 factory mounting holes via the included set screws. No additional hardware is required. The rings are 1 inch in diameter for precision mounting of standard 1 inch tube rifle scopes. They provide 1 inch of height, measured from the base of the mount to the bottom of the scope tube. The rings are designed with a see-through base, allowing for simultaneous use of iron sights. Milled from lightweight aluminum, the scope rings are 1.5 ounces each in weight.
