One point that needs to be addressed, at minimum, is the virtual trivialization of the alignment of the scope. Eyeballing the gap between the bottom of the turret housing assumes at least two things that are absolutely not guaranteed to be acceptable. First, that the bottom of the turret housing is dead parallel to the horizontal alignment feature of the reticle. And second, that you are going to do a good enough job doing that eyeballing that the alignment is correct. I kept waiting for the part where he SHOULD have told the viewer that this might get you in the ball park enough to get out to the range to finish the job. However, he proceeds to talk about tightening the ring screws (without a torque wrench) and then to Loctiting them down. Alignment to gravity has been totally skipped without even the suggestion that, for long range shooting, going further would be REQUIRED.

Alignment to gravity is typically done through on-range alignment of the vertical alignment feature with a plumb line positioned at (my preference) 100 yards – certainly some substantial distance.
