This is for those that have lever-actions with a cross-bolt safety.
If you carry your lever-action in a saddle scabbard with the safety in the "off" position (red showing). The saddle ring will prevent it from rubbing against the scabbard and engaging the safety. Therefore you will not miss that shot when you pull your carbine from the scabbard. I have heard that has happened.
The Winchester 94 saddle ring is easy to install. Just have a hole drilled and tapped. Then screw in your saddle ring. It looks good and still functional. Works on any lever-actions.
