Our new PeepRib Aperture Sight for CVA Accura, Kodiak, Optima and Wolf Muzzle Loaders combines a precision aperture sight with a scope mounting base. This Peeprib works with both old and new hole patterns. You can position a riflescope on and off your gun without upsetting your aperture sight! It's great for using a scope to fine tune your handload accuracy and you can just remove the scope when hunting regulations don't allow it. The PeepRib Aperture Sight itself is precision adjustable for windage and elevation and comes standard with a special High Definition Aperture for the clearest possible sight picture.

(Note: Threads on the aperture are standard 7/32 x 40)
