Scope Rings Not Level?

[jstanton]

How is it possible for one ring to be level but the other ring not?

I picked up a Wheeler Profesional reticle leveling system today and tried it out on my APR Maverick with Talley lightweight one piece rings.

I put the reference level on the rear ring, leveled the rifle and then indexed the barrel level to the reference level. I moved the reference level to the front ring just to double check and found that when I level the rear ring the front ring is not level.

I used an extra level to show the difference in the pictures below.

Am I missing something? Could the mounting holes on the action be off?

Lol that's pretty bad. I'd put that on remington before I did talley.

I'm no gunsmith. But, like you said, the holes may have been tapped incorrectly. Those aren't just a little bit off either. That quite a ways off level. I'd get ahold of APR. I'm told they're great folks over there. I've not bought from them (yet). But, I have met and spoken with a coupleasure of them at the TTHA show. They seemed like good dudes. Surely they'll get you fixed up.

I was going to suggest that maybe one of your levels was off. But, I see that you've already tried swapping their locations with the same result. That should rule out one of the levels as the problem.

You are dealing with tolerances in the action, D&T, rings & even the levels...it's common.

Look into the Burris posi-line rings. Center the scope to center and use the shims to center the scope, then fine tune scope. You could be chasing your tail otherwise.

Anyway I'd get with Apr tomorrow. Your pretty much sol on dealing with remington even if they did fix it or send you a new action you're out the custom work. See if Apr can bump the screw size and re center in the process.

What you're leveling doesn't even really matter if its level, correct? It's a round scope going in a round hole. The scope needs to be level with the gun but what does it matter if that section of the ring isn't level?
Level the gun
Hang a plumb bob across the room and level crosshairs to it
Tighten correctly while checking for scope rotation
Done
What happens when you remove both bases and check both levels where the rings mount?

You are dealing with a stack of tolerances and checking something that doesn't matter. Lap the rings, level the scope to the rifle (bolt raceways) and go shoot.

APR isn't open on Mondays. I have a machined 1" bar round stock. I'd clamp it int to see if they are aligned to each other.

It does matter if it's level. You are not dealing with something that is rotated concentrically. If it's out it is pushing the rear of the scope right or the front to the left.

R700 Talley lw's. Wheeler level.





R700 Seekins base and rings





I could do this with more rifles but i don't want to pull scopes. I would expect lapping to account for small variances like these. Something is up with op's rifle.

I'd absolutely get it checked and fixed. And if APR didn't mount the Scope then they didn't know. Far from the first time Remington has screwed up mounting holes.

I don't think it's a tolerance stackup issue, since there's only 2 parts (receiver and scope ring).

I'm guessing the base of the one ring was not machined properly, maybe whatever it was clamped in when it was cnc machined was 'off'.

X2 on contacting APR. If you've got a spare set of rings, of ANY height, try them - that should help you determine if the problem is with the rings or the holes in the receiver.

Question: if you cant the rifle so that the bubble on the front base is centered in the level, is the rifle obviously not sitting plumb?? Seems like, with the bubble that far off, your rifle would be obviously tilted, if you tried to use that (bottom half) as your reference point. IF you determine that the front is what's 'off,' take the rear ring (as you have it set up in the photos) and move it to the front mounting holes; and see how the rifle sits. Make sure you leave the barrel clamped level, from the Wheeler system, on the barrel while you move the ring/base. If the levels, then, match up (after the rear ring/base is moved to the front) you'll know the issue is with you rings/base. If the problem repeats itself, then the problem is definitely with the screw holes in the action. Hope I explained it clearly. I'd sure be itching to know if I'm dealing with a problem with my rings or the mounting holes in my action - one's a LOT bigger issue than the other! Should be pretty simple to determine the issue at home, using one of these two tests I mentioned.

Not sure how some of the people responding expect you to "level the rifle" with the problem you're having. Unless there's another flat surface on your action that you can use to level the top of your rifle or plumb the side of it.

God luck and keep us updated!

Do a test please.
Set it up like in the original photo, with the rear ring and level, and the bubble in the middle. The put the removable level from the front sight on top of the read level. Is the bubble still all the way to one side? I want to rule out that the base on the removable level is off.

The bolt races as someone else mentioned.
