Prevents uneven pressure from being applied to the scope tube. A scope tube that is stressed and distorted will never track true, and be much harder to sight in and make repetitive adjustments.
No problem I suppose if you are going to sight your rifle in one time and never touch the turrets again.
If you plan to dial for wind or elevation, going to be hard to do with a scope that doesn’t track.
In addition, as has been alluded to previously, it increases the clamping force by ensuring even contact across the full surface of the rings.
That’s odd.
I don’t do any lapping and have had absolutely no issues with tracking on my scopes. They’ve all been adjusted to their maximum elevation at one point or another.
By “all” it’s really only a couple that get that kind of workout. And SWFA 10X and Viper PST Gen 1. I love cranking in the turrets. For wind holds I’ll dial in most of it and only make small adjustments for changes.
I have no doubt the SWFA 16X will perform equally well.
As far as clamping force, they’ve held tight on an Armalite AR50.
