Oh the joy of scope mounting! Getting everything level and plumb using gun vise and bubble levels. Only to find when shouldering rifle that the vertical ain’t vertical and the horizontal ain’t horizontal! Everything looked good and much care was given tightening the scope rings but alas the scope seems to wander under that sequence. I was given a tool by ariska products that looks like a great and easy answer to level and hold the scope tightly while the scope rings are being tightened. Haven’t tried it yet ,but brownells has a video on its use.

I have the opposing wedges from Arisaka that you mentioned. They work great for many, not all applications.
That said I've never had an issue eyeballing it. I just tighten the rings evenly - enough to keep the scope from spinning freely but loose enough for me to twist it deliberately. Check several times, shouldered and/or rested on bags, adjusting as needed. Then properly torque the screws in the rings.

The Arisaka tool works like a set of machinist's height adjustable parallels.

The worse I've seen for scope movement when tighting the rings were with Weaver rings, the type that the top ring half only has screws on the one side and the other end has a hook that grasps the ring body bottom. Those are the worse for me.

I like to keep this on the scope and barrel throughout the process because it gives a true vertical through the scope and bore. www.brownells.com/optics/rings-mounts/scope-mounting-tools/vertical-reticle-instrument/Then use this bipod to level the above device because of the fine adjustable legs. I really dislike gun vices for this job. www.brownells.com/gear/bipods-monopods/bipods/f-class-bipod-sling-swivel-mount-wquick-adjust-elevation-knob/And line the vertical crosshair up with a fluorescent pink string and plumb A torque screwdriver set to about 20 lbs. alternating side to side to keep the reticle level and the gaps on the rings equal. I usually get the front fully level and tight, then the sequence for the rear is just about keeping the scope ring gap equal because level is set. This step may take a try or two because as you note, it’s easy to get very slightly off level here. While it’s set up in this way I pull the bolt and bore sight it the old way. My brain dislikes canted reticles. Though eyeballing it is adequate for all but precision shooting I’m happier if they’re “perfect” and now that I have the process down it’s faster than eyeballing it (deciding my eyes were wrong, redoing it).

I missed it was out of stock and didn’t realize it was scarce now. I should stop recommending it then lol. 3D printer plans are available and I’m sure an Etsy seller would print one. www.thingiverse.com/thing:4964611

Various tools to straighten scope mounting is like various tools to sharpen knives in my house. I don't need another if I can't make do with what I have I don't need to be playing with guns or knives

I have tried every gizmo, gadget and gimmick to get reticles perfectly level. Now I do the best I can, shoot the rifle to zero, shoot a group, click up 4 inches in elevation, shoot a group, click 8 inches down, shoot a group. If the groups are at a slant, the scope gets adjusted.

Please don't let Trey know I said this but that's pretty genius.

Please don't let Trey know I said this but that's pretty genius. Different methods for different scope uses. If you're going to use a reticle to estimate drop and drift, then getting the reticle level is the goal. This method ensures the reticle is in the X/Y correctly. If you're looking to compensate for drop/drift using the turrets, Trey has it right. That method ensures the erector is in the X/Y correctly. Be prepared to re-mount your scope at the range if this is the goal. Ideally, your scope and gun are built with enough precision that they're the same thing but that's often not the case. The difference in POI is typically small at most ranges- not something a hunter would notice.

I only shoot iron sights on revolers and rifles now because mounting a scope is such a pain

To level crosshairs, I use a combination of steps: * Rings just loose enough to rotate scope by hand. * Point at sky or neutral background. * Natural light preferable to artificial light. * Sandbag rest and offhand. * Sight with fresh oxygen. * Limit sighting to a few seconds... avert eyes, taking fresh oxygen. * Sight handgun or rifle from right and left hand positions. * Adust eye relief to satisfy all positions of marksmanship. * Put gun down... pick it up again... verify. * Gradually tighten rings in rotation pattern, like rotating tires. * Verify.
The reason to not hold a position for long while leveling scope is to avoid the mind’s tendency to adapt & compensate.
A machinist’s vise doesn't level if the frame and mount holes are out of square. David Bradshaw
