+1On this site I would expect to get many recommendations for "tactical" style rings & bases. I've got them too and they are very strong and work great.
However, my favorite ring & base combo for non-tactical rifles is the Burris Signature rings w/ plastic inserts and their bases. The Signature rings can solve/prevent many problems while introducing none. I have never had a scope slip in Signature rings.
Just my 2 cents.
