EABCO’s "Slip-Over" Ruger#1 scope mount solves the problem of aligning an after market scope base on a contoured barrel… It uses the factory pre-aligned rib as an alignment shim! Now you can have a precisely aligned Weaver style scope base on your Ruger #1 Installation is Easy – Remove the screws from the original rib. It will stay in place with the recoil pins. Slip the Slip-Over Mount onto the rib. Install the replacement Allen screws. Mfg: E. Arthur Brown Company, Inc.
