I was recently mounting my Swarovsk AV 3-10x42 on my Rem 700 with Talley medium 1 piece rings.  When I tightened the screws on the ring mounts, the know to turn the power magnification from 3-10 was very stiff and rough.  I loosened the screws and the knob turned easier.  I took the scope off the mounts and the knob turned fine.  I mounted this scope no different than I had my Leupold before and never had any problems with the Leupold.  The rings were just as close to the eye piece as they've always been.  I slid the scope down a bit and didn't have as much of as a problem, but still couldn't get the screws tight enough for my comfort without hindering the knob/turn to change the magnifiaction.  Plus, I know have scope ring scratches on the scope.
 
I'm really frustrated.  Any ideas on what's going on?  Makes me think the tube on the Swarovski is weak.  Assuming I can get the problem solved, any ideas on getting the scratches off the scope tube?
 
Thanks!

And how tight is tight enough? I don't know what you are using for mounts, but I run 15 in/lbs (not to be confused with ft./lbs!) on my Talley lightweights. This is about as much torque as you can get using the short side of an allen wrench. If you are crushing the tube of the scope, that's not good, and I would guess far more than 15 in./lbs. I can't offer too much help for getting the scratches out of your scope tube, but it may be an indicator of torquing the screws too much.

Or just mount a Leupold!!!
 
If you are not exceeding torque specs then the scope is faulty. I have mounted a lot of scopes and have never experienced that problem. I only hand tighten the grub screws and normally stop just before the allen key snaps.

  My first guess would be if are or are not torquing the rings to the correct manufactures specs?  This will cause a lot of mounting issues to those who think tighting til they can't turn anymore will cause the scope to be extra secure....  they give torque specs for a reason.  If you are to specs then it could be your rings are incorrectly machined.  I actually got a package of talleys once that had a medium and a high in it so I've seen mix ups happen, check the rings for the same size, its listed on the bottom of the scope.  If could be your base is warped, or even you reciever on the gun.  Then again it could be the scope but I highly doubt that with it being a swaro and all.

Also, make sure your rings are in alignment and square with each other.  It is possible that either your rings and slightly out of wack, or even your reciever is slightly out of wack. 

But this is most likely an over tightening issue.  Lots of people have problems like this.  15 in lbs is not very much at all.  So if you are using a screwdriver or the long side of a hex wrench it is very easy to double or triple that without even realizing it.  Which causes the exact problem you are talking about.

I'm pretty sure we've nailed it - I'd bet money that screws were being tightened way beyond what was recommended.  I'm going to get me a torque wrench that will give me the exact amount of torque I need to put on those screws.

Little late now if you have crushed the tube into the erector assembly. That can cause irreparable damage to the scope. Over torquing the screws will cause them to stretch and come loose. With proper torque they will hold very well for a long time. Good luck on your scope.

Muleymaddness,

 

From your above description it does not sound that you have done any damage to your scope by exceeding the elastic limits of the scope body.

From the previous posts above in order of decreasing severity  

1)    Over tightening the screws

2)    Bad alignment in rings and/or base – If you find this is the case, try a gunsmith that has a scope mounting alignment too and have him check it out.

Good Luck,

dsr
