Leupold Mark 4 30mm High Matte Aluminum Scope Rings (part no. 57291) give a large-objective 30mm optic the clearance a precision or tactical build demands.

Included 6-48 and 8-40 screws plus half-inch keeper nuts cover high-recoil platforms out of the box. Among high-profile scope rings for 30mm tactical and precision optics, this Mark 4 set is ready to mount and go.
