Im sure you will like the base, but I thought id better throw in this little thought on the rings. They all have differant thicknesses, but are sold that way ie. thickness, not moa gained. Here is a little chart showing possible moa with 0,15,20,and 30moa bases. Lines with stars are also avalable for 30mm rings.
With a .020 in the back, and a inverted .020 in the front (.040 total) you will only get 24moa.
As you can see, with a long action like 30-06, some of the moa values quoted are a bit optimistic. Values gained change with ring spacing and the formula for calculating exact moa values is included at the bottom of the page. Measure rings outside to outside.
