I've been using the Talley 2 pc. ones with very good results. BTW, I have a set I just took off a Remmy 700 VSF. They are 1" Lows, and were used with a Bushy Elite 4-16 X 40 scope. $20 (for the rings) if you are interested. The scope is also listed for sale in the classified section. PM me if interested.
