I’m swapping scopes between two rifles. The existing ring screws were loc-tited when the scopes were installed. I want to just use new screws rather than try to clean up the old ones. What size are the ring screws for Talley light weight alloy rings (Tikka). They kind of look like 6/32… but I’m thinking they might be 6/40. Anybody know for sure?
