These rings are medium height for a 30mm tube scope. These are made specifically for tikkas. They fit perfectly on the dove tail on the receiver. One has a recoil lug that fits right into the receiver so they will never move. Made of steel so they are super solid. Clamp great. I just changed to a 20 MOA rail so these no longer fit. They were on the gun when I bought it and previous owner said he only fired 3 rounds and went hunting once. They look perfect cosmetically.

This is from their website:

Tikka's innovative receiver design includes dovetail grooves, meaning an owner doesn't have to worry about equipping a scope base. That means using Warne Maxima Tikka rings gives you plenty of strength without a heavy weight. Made with premium materials, these 14TM 30mm scope rings feature a medium height and a vertical split. Their redesigned recoil pins offer a stronger bearing surface for rifles with stronger recoil
