Burris Quality control

[Luisyamaha]

I've had a Burris 2-7X EER scope for 15 or 20 years now. I had low expectations while mounting it on a 8mm Mauser. But somehow it was still there and working fine until I sold the rifle a few months ago, sans scope. I have no more use for it, but there it is!
My all time disappointment was a Simmons. Even a couple Konus I got gave me better service, but that's another story.

Have you tried the problem scope on another rifle to see if the same issue exists?

If a scope if off center the way you describe, I think it would have almost no ability to be adjusted side to side.

Conversely, if it can be moved the expected amount side to side with the knob, then it cannot be very far off center, because there is not very much extra space between the erector tube, and the wall.

If the crosshairs themselves were far off to one side, yes, that would be a problem, but you would have already noticed that the reticle isn’t close to the middle of the field of view.

I recently moved that scope to a different rifle. I did break down and buy the shim-able Burris z rings.
It's the scope.
