CSM,

Just for your reference - this is the standard EGW base with a set of Burris Signature Zee rings. Lots of options for bases, but the Burris Signature Zee rings are my #1 choice. Some say they are not appropriate for heavy hitters (e.g. 300 RUM) but I have given up on such calibers as I have become older (=wiser).

Luck, Tim
