I have tried amny things to accomplish mounting my rings, from brrom handle to old busted scopes in order to avoid damaging the new scope that I was mounting. In all cases, I did it. Shot well and have record book heads to show for it. BUT, this tool is a pleasure to have in your optic tool box. Buy and see it for yourself.
Pros: Designed to do what no other tool does
Cons: Absolutely nothing comes to mind
