unnecessary????
Why unnecessary? Are you some sort of Fudd? Unnecessary because you don't shoot long range maybe.
I shoot pop cans at 300 yards and cannot dial for it with a 20 MOA rail because the rail does not have enough slope. I have a steel plate at 375 (from that firing point) and I have to hold high for that with the magnification reduced to get the target inside the field of view.
With these rings I can set exactly the slope I want.
Ever heard of a zero stop scope? These rings can be set perfectly so they provide a zero stop just a few minutes off the lower end of the scope travel.
As far as I'm concerned, if you are into CRPS, these rings are where its at and if you don't have them, you are behind the curve.
Perhaps he's referring to unnecessary scope ring height.
The use of a .25 MOA rail in addition to Burris Signature Zee rings with the offset inserts in both rings gives a lot of elevation without ring height being unnecessarily high. Not only that, they have aesthetic appeal unmatched by the likes of the FX, Sportsmatch, or those shown in the picture above.
