Maxima rings for ruger m77 mk ii - Warne Maxima Ruger Rifle Scope Rings for 30mm PA Ruger M77

Solid rings, great finish, quality machining. Only drawback - installation is somewhat tricky due to the vertical design. The rings have to be loosely assembled on the scope first (don't forget shorter ring towards the muzzle, taller ring towards the butt), then set on the Ruger rails while making sure the recoil tabs don't fall out the bottom of either ring set. The plus side to the vertical split is that torquing the screws does not twist or cant the scope after leveling the reticle, and you don't have to worry about setting an equal gap like most horizontally split rings. In case it helps someone else, M77 Mk II sporter rifles with 50mm objectives need medium height rings. I bought high and had to exchange for medium.
