Low mounts to fit a30 mm scope. These have 6 screws for each ring. They were fitted to my .308 tikka with a picatinny rail. I had a 50mm objective lense scope with enough clearance. Can't guarantee you can fit the same as depends on bold clearance and barrel profile.
Only switches as have finally got some Burris signature rings that allow we to add 30moa to help with long range shooting.
Have been on rifle for 2 months as a stop gap while waiting on the Burris. 22 posted.
