Scope leveler...

Your instructions are clear and this will align the reticle with the muzzle. But does this ensure that the scope tube is also aligned with the bore? If the bore is angled slightly differently from the scope tube, won't shots at various distances shift left-right of the vertical reticle? Is there a way to check and fix any bore-scope tube misalignment without shooting?Here's a step-by-step that I wrote up a few weeks ago.
How important is perfect level your scope to your gun?
I see people attaching bubble levels and whatnot on there guns and scopes trying to get perfect level. How would you know your gun is even level? Since most guns aren't flat on top how would attaching a level on the barrel you know its even level. So when I install my scope. I hold the gun to...www.airgunnation.com
The number of steps will initially make it seem more complicated than it actually is, but don't hesitate to ask questions if something isn't quite clear.

No, but the scope tube does not need to be precisely aligned with the bore. The erector tube does, since it is the thing we are looking through to aim.
In other words, if we didn't have a floating erector tube inside the scope body, and the ability to manipulate it via the turrets, we would need to be concerned with precisely aligning the scope tube with the bore.

Local shop near me uses those to install all scopes.Hi all,
I would like to know your thoughts on this type of scope levelers...
Is it worth buying them?

Perhaps the "only" advantage of this method compared to other, let's say, more traditional methods (i.e. the use of plumb line, bubble level, mirror method, etc.) is the time savings.

IMO, if the scope isn't true... tube to reticle to turrets... you're screwed any way you go. Sure you might get the reticle plumb, but if it's not true to the turrets the minute you dial you introduce error. At that point you've only got whatever holdover you can see at a particular zoom level.
Spend more money and get a better scope.

It saves time in that it makes the bottom of your scope line up to the top of the rail, but as mentioned, neither of those is guaranteed to be level. But if both aren’t level… did you save time?
That is why people do the mirror method and such.

I used one of those tools to put a scope back after checking some shorter rings a few minutes ago. I don't think there is a perfect method. Most, including the mirror, require the gun to be level. How accurate is your level? Setting the flat bottom of the scope turret area parallel to the picatinny rail depends on the gun and scope machining and possibly assembly. It wouldn't be a bad idea to check with another method but I suspect machining is more accurate than most levels. It is certainly a quick and easy method to at least get close.

Maybe... But verify your results with the "tall target test"... these fudlore methods can be accurate... But doesn't prove they will be...

OK. But having the muzzle line up with the scope bell at a fixed distance (in the mirror) doesn't ensure that the erector tube is parallel to the bore, does it? Don't you still need to shoot at 2 (or more) distances to see if there is any x-axis shift with distance? If there is, should you shim the scope CW or CCW to the bore until the x-axis swing goes away?

vertical plane,,, verticle reticle, alignment of gun bore with verticle reticle,,, THAT IS THE KEY,,, that is all there is,,, period
alignment in the same plane,,,, but not parallel
we are intersecting a verticle line to a horizontal bore hole
as to distance, we use 20 MOA rails or dial or just hold under /over,,, that depends on shooting distances or your usage

@thomasair so to be sure, you mean in the example above to rotate the scope CCW? as you sit behind the scope which would place the lower vertical reticle on the POI?

shim? perhaps rotate the vertical retical ccw or cw to bring the poi in agreement with poa ? I was just thinking about this as @thomasair mentioned it earlier in the thread.

Yes...ccw from behind. The reason this method is better is because the distance doesn't matter....it's the amount of holdover or clicks away from zero that matter. Super short distances require a lot of holdover or clicks. Super short distances also have very little wind drift that could mess up your results.
