Recently picked up a contender frame and expect to visit a local gun show Dec. 28 or 29, to find a barrel. Will be looking for a 7 X 30 Waters, in either 12 or 14 inch length. But my real question here has to do with rings and bases for the scope. I am planning on purchasing the Burris signature rings with the pos-align inserts. Does anyone have any recommendations regarding the base? I am planning on the Burris base, based on the assumption that the Burris rings should work best with a Burris base, but was wondering if anyone has and input on the Burris base or any other brand. Anyone have any problems with the Burris base? Anyone prefer a different brand base, and why?
