The PEPR mount is fine for a 1-Yx scope. But I agree, I would not use one for a long range setup.
Except the scope does not need to be leveled to the rifle.
The scope needs to be leveled to the world, when you are shooting it (normal hold).
Poor man's scope leveling trick...take a feeler gauge
...
It might not be as precise as the scope leveling kit / bubbles

Its likely more accurate than 99% of people levels. You can pretty much guarantee the adjustment mechanism is square to the housing. The reticle could still be mounted canted and it would work right.
I don't think this is correct. If the scope isn't in the same vertical plane as the rifle AND square then any distance change will introduce windage errors. Negligible at 100m but at long distance the errors add up quick.
Underneath is fine. I said scope/bbl in same vertical plane. Below is still verticalYou could mount the scope on the bottom of your rifle and it wouldn't matter if your scope is leveled perfectly.

So taking your example to only half as extreme, hold the rifle sideways (vs upside down.) Typical height over bore on an AR w/ a big scope is 3"-ish. If you zero at 100 yds, at 1000yds you'd be 30" off windage. The sine error is small for small angles and may be smaller error that you and/or the gun are capable of but to say "it doesn't matter" is wrong. FOr a gun tha is tilted you actually need to set point of aim @ your zero distance to be the same as the horizontal mechanical offset and not on the crosshairs. There is a reason that precision stocks have adjustable drop/offset/cant buttplates.

It isn't correct and you just used the EXACT same types of examples as I did to prove it. I even mentioned the sine angle error will be typ small.It is correct.
I am aware of scope cant error. I can do that math too. You know it doesn't have to be an either/or proposition. There is also a neither option.Which one would you prefer to have?
