These rings worked out great for me - Vortex Razor HD 35mm Steel Riflescope Rings, Pair

There are not a lot of options for 35mm scope rings out there, and I needed something that would work with a narrower weaver sized cross cut in my scope base. Vortex's other rings are made by Seekins and they would not work with the slightly narrower cross cut in my scope base. If your scope base has a weaver sized cross cut and you are looking for a ring to mount a 35mm tube scope, these rings are great. They are extremely well made and heavy duty, they mounted my razor hd perfectly and it has not moved after shooting. I would recommend these rings to anyone wanting a steel 35mm scope ring.
