I have a Model 10 with an EABCO varmint contour barrel with a picatinny rail that I need get up and running. I'm waiting on a new Weaver tactical with a 50mm obj and was wanting to using Burris Signature rings with the inserts. Couple of questions, which height rings should I use to get the scope as low as possible?

To get a 20MOA incline on the scope, do I just need to order the +/- 0.02" inserts? I'm guessing the +.020 would go on the back end and the -0.020 would go on the front end.

Last dumb question, do Weaver style rings attach to a picatinny rail? If not, which Burris rings do I need?

Thanks in advance.
