Hi Everyone. I was just wondering if there are any tricks in keeping the elevation settings from coming loose when using a tang sight. My worst offender is on a Remington 14 with a tang sight. I see that Marbles has a locking collar for the elevation screw but all I have are Lymans and they don't have a locking collar. After shooting, the elevation collar vibrates loose and so does the elevation setting on the stem. Someone once told me to put a dab of epoxy on it and then if you want to change it you can just heat it with a match. I am not real excited about doing this and just wondered if anyone had better ideas? THANKS!
