That definitely sucks, but send it back. Maybe they have some one new working there that is still learning the trade. I sent back a VXII (last year) and thought the windage adjustments were backwards after I got it back, but got it zeroed and haven't touched it since.

If the tube is bendingwhen you tighten the rings maybe it is the mount setup that is off by a few thou..

Move your rear ring back or forward so its not crushing the recticle.
As mentioned, the rifle is a cz550 magnum, no leeway for moving that ring. And the scope is an M8 compact 2.5x20... there is only like a 16th of an inch that it can move back and forth... I'm thinking I'd better call Korth...
Are you also using Leupold rings? Some have reported that they don't always line up ( http://www.africahunting.com/375-up/1837-cz-550-scope-mount.html - #7 ).
The reticle shouldn't bend as you tighten the ring unless you are bending the scope tube - which will happen if the rings are not aligned ... options include replacing the rings or "lapping" the rings. It is also possible that the action scope mounting grooves are not aligned. Anyway the 2 1/2 is a pretty light scope ...if you can get a good grip on the front of the tube - and simply use the rear ring to "align" (eg snug) rather than reef it down that may be sufficient. I use Lynx rings as well as the factory rail mounts on my ZKK's and they all work fine FWIW.
I have seen Leupold tubes badly marked and scored after rings were tightened up smartly -- not my favorite scopes frankly and generally over rated IMHO. I have a few - including the little 2 1/2 which I purchased for its light weight - before the flame wars begin...

The reticle doesn't mount directly to the external tube. You'd have to be crushing the scope pretty badly to bend the wires by compression. I suspect that the "bending" is an optical illusion caused by some lens or element getting moved when you tighten the ring(s).
I'll bet that if you remove the front ring entirely and just 'cinch-up' the rear ring you won't see the "bending". (of course I'm not suggesting that you shoot it like that, it's just done to eliminate the front ring as a source of torque.)
Any chance you can beg-or-borrow some sort of rig to check you scope ring alignment?
(My ring-lapping rods are from an outfit that rebuilds hydraulic cylinders, it seems that 30mm and 1" shafts are reasonably common sizes).

actually in a fixed power scope the reticle ass'y "may" be mounted directly to the tube. and in the Leupold 2 1/2 could very well be directly "under" the rear ring. Many fixed powers only move the erector ass'y to adjust for windage and elevation while the reticle "cell" stays put - unless it is disturbed by something. I am thinking that if you crushed the tube enough to deflect the reticle in this fashion your scope may not be 100% now. If the tube was "torqued" to cause this apparent distortion you may be fine...in any case if the same rings and scope were mounted ok before - I would look at the "rails" on the action to see if they are being engaged the same way as before - eg are the rings in same place .. a little bit ahead or behind? some roughness in those grooves could upset the position of the rings on the receiver.. fwiw. It would be worthwhile to remove the scope and mount the rings in the same place to see if you can detect any issues/poor alignment - My ZKK's aren't exactly finish polished like a Rigby.
(incidentally I don't have any beef with the mechanics of a Leupold - considering the excellent lightness they achieve - which is always a trade-off - they are pretty darn good; as is their warranty. I guess my beef is the absolute conviction many Leupold users have that when they look through them they can see the "Holy Land" while all other scopes are akin to coke bottle bottoms! This simply is not true.)

Most people over tighten the rings. 20 in. pounds is all that is required on Leupold rings. Not sure on warne but have seen a lot of tubes damaged with them so I would guess you can over tighten them fairly easy.

Lap your rings. Due to manufacturing tolerances and the differing processes of various manufacturers (rifle, base, ring, etc), it is inevitable that something will be out of spec and it only has to be a very few thou to cause negative effect.
Lap your rings so that you are seeing at least 50% wear on the bottom rings and your scope will sit much truer.
1" steel bar + lapping compound + elbow grease = level scope mounting...

drill a hole into the end of that bar and then screw in a lag bolt, attach drill, and rotatation goes much faster, a lot less elbow grease required, unless you are a machinest and can mahine down the end of the rod to fit the chuck
