Hello I’m looking for a 20 moa scope mount for my older 308 ctr, but none have the 5 torx screws and 2 drift pin set up that mine has? Has anyone ever swapped one out on a ctr? From my research it looks t3s normally have 4 screws and no drift pins? What’s the best way to pry the mount up because the screws are out and it ain’t budging
