To take advantage of the 20 MOA slope, the rings will have to be spaced to a location that gives you a true 20 MOA. It's possible, the rings are too close together.

His rings from base to center are the same height and they are positioning what amounts to a straight cylindrical tube. The rings are mounted to a rail that’s flat over its full length topside but it’s an inclined rail higher at the rear relative to the barrel’s bore center in how the rail is mounted to the receiver. So, what’s ring spacing got to do with anything in this case?

The ring spacing changes the distance between the barrel and objective. The rail is flat, but tapers towards the barrel. As you move the front ring towards the end of the rail, the distance between the barrel and objective decreases. Moving the front ring towards the rear ring increases that distance, because you are raising the height of the ring as you move towards the higher portion of the base. Measuring my Kelbly F-Class action, the 20 MOA rail consists of 14 slots. Each slot represents roughly 1.5 MOA. Working from rear to front, the rear is zero. Moving forward, each slot increases by roughly 1.5 MOA. The last slot in the rail represents 20 MOA.

So, is the reaction mechanism triggering this feat via the same FM causing reversed thermal expansion characteristics in rifle barrel steels experienced only in a nuclear power production environment? ???

Just use the negative space wheel adapters , it'll be fine .

Did you get it sorted out?
If it's a removable base most likely it is on backwards with the taper to the rear instead of the front. easy to do.

When you're done checking this, go out to your car and check your muffler bearings and your blinker fluid.

Don't forget the kiniflin pins, bumper bearings and wheel weight thrust washers.

Seriously though, on backwards, wrong bases or bases are different and front and back are switched.

Looking at the number of PM's I received, I had more than one believing it ;D

So, the above, now missing, post was only the bait for seeing what you might get stirred up, right?
Of course, you knew all along that for his rail and rings combination, your “advise” was total BS, right again?

Got it, will check this. Thanks

Next morning, Bill “Got it”, maybe, and offers thanks in return for your totally BS advise. Hopefully, he got it immediately, before wasting any time and effort only to end up stepping into your bait pile of BS advise.

Just enough info for any folk that were still unsure as to what exactly that JRS guy is full of…

Ha – filling this one under “Nuclear BS”, alongside your other best of the best BS.

Knowingly, intentionally trying to lead folk astray with your utterly nonsensical BS, continue to spread even more BS after you get called on it, and then finish up with a brag and grin. You’ve certainly put on an amazing display of character. Yo mama should’ve drowned you as a pup.

20 moa spanning 6" is only about .035" of taper. There are many variables that can reduce that back to near zero...things like action bedding, the machining tolerances on the mating surfaces atop of the action, machining tolerances on the base mating surfaces, action screw torque, ring to base tolerances....many things that can combine and easily transfer to the scope/scope body.
