Might be a dumb question, but I'm gonna ask anyway. Is there any problem in using Weaver type rings with Picatinny bases? That is what I am using, and it seems to work just fine. Actually, I have risers on a Picatinny base, but the risers look the same to me as the base. Main reason I am asking is I just ordered a Leaupold scope, and I have never owned a expensive scope before, and I want to make dang sure it stays attached to the AR! So, do you see any problem with this set up, or should I buy rings specifically for the Picatinny base.
