Leupold 51039 Ringmount Rings Dovetail Ruger #1 & 77/22 30mm High Black Matte

Designed to accommodate firearms with unique integral mounting systems, these ringmounts are a high quality alternative to ringmounts sold by firearms manufacturers and as a no-tap mounting method for most .22 rimfire rifles with an 11mm, 13mm, 3/8" dovetail rail. Leupold ringmounts feature superior integrity and tighter tolerances because they are machined from solid stock. Also available in Extension rings to provide 5/8" of additional fore and aft ring spacing.
