Re: 1" vs. 30mm ..?
Jake, If its a decent deal go for it. If need be you can pick up a set of burris sig. rings with the inserts for around $50. Those will get you to 1K with no problem.
1" tube shouldn't be a problem on any scope with quality optics in it. Just my opinion.
Ignorance can be treated with education, sadly there is no cure for stupidity.
