My CZ527 Varmint didn't come w/ rings either.
I prefer the split rings by Warne anyway so I ordered a set of the 16mm Warne Permanent high rings.
I've used two different scopes on this rifle - first was a Nikon Buckmaster 6-18x40SF which I liked but decided not enuf power. Currently I've got a Bushnell Elite 4200 6-24x40AO which I believe is one of the best deals in glass going. The occular cleared the bolt "barely" on both scopes.
I'm going to attach pics of both scopes, mounted on the rifle, using the Warne rings.
