I have always liked the plumb bob method. Did you sight down your bore to see if the plumb line is centered there, too?
I have these wedges from Arisaka that are pretty slick but even the small ones are too big sometimes. The flashlight and plumb bob work on everything and I always verify that way.
Now how are you leveling the rifle? And also in the field while shooting?A plumb line and a pair of bubble levels too overwhelming for you?

There's a corollary to this among watch aficionados - It's said that a man with one watch always knows what time it is but the man with two watches is never quite sure. Wise words if you think about it.
The EXD tool he has basically accomplishes that goal. I think (not an engineer).Now how are you leveling the rifle?
The EXD tool is intended to be used in conjunction with a plumb line to verify the vertical reticle line is plumb as well.The EXD tool he has basically accomplishes that goal. I think (not an engineer).
I own one, and in short, it tells you when two circles are stacked plumb to each other (outer circumference of both the barrel and scope objective bell). Theoretically, if those two circles are plumb then your rifle is too.
Next, you can level the reticle against a plumb line, tighten the rings and go on with your life.
I don’t use a flashlight, but just look outside at a neighbors house. I assume the house is built plumb, but that’s not a sure thing!
Caveats apply:
I’d like to buy a picatinny fixture to accomplish leveling like lowlight/Frank does, but I suppose there’s no guarantee that the fixture’s rail and the rifle’s rail are equally “flat” (I’m sure I’m using that word wrong here). Almost certainly an insignificant issue.
- Its bubble level is to be believed, of course
- Assumption is the bore is in the dead center of barrel (not a for sure thing, apparently)
- Assumption is that scope points exactly along the line of the barrel (hopefully close enough)
- Another assumption is that the barrel and bell are round (enough)
- Also we assume the action is level in the stock/chassis, otherwise the butt won’t be perpendicular
- Can’t really use it on an AR-type handguard. Needs a bare barrel to index off of.
- Probably more…
A bigger issue for the fixture is ease of use in a house. The fixture potentially needs a little more setup, like a base on a very stable tripod or something. Or you have to go to the range with it.
One can simply use the EXD with a rifle in a tripod.
Anyway, the EXD seems to work well, but as an engineer will most likely point out, I’m probably wrong.
I think that graphic is strange.
Yeah, I know. I’ve done it that way, but I’m lazy.The EXD tool is intended to be used in conjunction with a plumb line to verify the vertical reticle line is plumb as well.
That’s still not the exactly correct take of that diagram as far as how the EXD tool works. It’s condensing two steps into one (left side), and added two meaningless diagrams (right two diagrams).

Or, as e.e. cummings might write:In fact, when I order a scope, I stop using capital letters all together, preferring the writing style of E.E. Cummings, to ensure I am at the top of my game when the scope arrives.

Shouldn't it be "I like the way you hang sir."Pretty cool. Good to be sure. I like the way you roll sir.
