Our PeepRib Aperture Sight for CVA Accura, Kodiak, Optima and Wolf Muzzle Loaders combines a precision aperture sight with a Weaver style 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.
An aperture sight (aka peep sight), mounted as close to your eye as possible, removes a huge amount of aiming error by simply increasing the sight radius (the distance between front and rear sights). Also, aiming error from rear sight light reflection is virtually eliminated with an aperture sight... so that the angle of the sun will not change your point of impact. Finally, the aperture itself improves the focus of your sight picture by funneling the light through a hole. (A camera will do much the same thing when you reduce the size of its aperture... the depth of field improves).
(Note: Threads on the aperture are standard 7/32 x 40)
