I just eyeball it.

You can detect less than 1 degree off of perpendicular with your eyeball.

You might be able to find a flat spot on the bottom of the stock, but the receiver is bedded to the stock (possible rotation) and the barrel mounts to the receiver (another bit of mechanical error) and the scope rail mount to the receiver (errors), rings (errors) and the top of the scope adjustment housing (errors) in relation to the reticle (errors).... and people want to measure using a quarter inch bubble in an inch long tube of yellow water???

People that sell yellow water made this idea up.

Make it look right and it will be right. It’s not polymer science or baking. And as said above, the proof is in the shooting, not a bubble level.
