I sure wish that there was one best mount system. Over the years I have accumulated and used many types from the basic Weaver thru German claws.
At the moment I have switched more rifles back to the Weaver bases. The thing is that I like to switch scopes around and also at least be able to use iron sights and the Weaver base is very low yet strong.
I have some one off custom mounts as well and for the money I like the Weaver Quad Lock at the moment. I have a burr under my saddle about the gushing over Talley mounts and yes I have them too.
