This scope has a power range I think ideal for my 30-06. Would it stand up to the recoil? Would the parallax have enough adjustment?
Yes it will stand up to it. And it does not have any parallax adjustment, it is a fixed parallax optic.
Will this scope survive hunting usage on a magnum springer air rifle such as an HW95, Beeman R1, etc.?
Yes leapers are known for there strength.
This scope has a 35 yard parallax setting. What is the minimum and maximum ranges at which you have a crisp, clear image?
When using the lower magnifications, 1x-3x, you should be able to get a clear picture (both reticle and target in focus) at 10 yards on the low end. Any magnification higher than that, either the target or the crosshairs will blur out. On the high end, over 100 yards you should be able to use full 8x without issue. I cannot say for sure where you would be able to use the maximum magnification between 35 and 100 yards. Likely around 75-80 yards it would begin to clear up again, but hard to say with certainty.
does this come with rings?
No, rings are not included
