I only have .020 clearance according to my feeler gauge. Is that enough? Seems alittle close to me. Its a 56mm objective and I have the Badger medium alloy rings...
Re: Clearance between the objective and the barrel ?
What are you putting this on? If it is a .22 then no worries....but obviously if you are cutting it that close with a bigger bore gun you could have some issues. Is it a heavy barrel...countour wise or is it tapered? Many factors for this question.
