Please don't think I am downing you. We sight in rifles as a side business, and I only look at past experience as an indicator of possible problems. And I am sorry to say that is a model I would be suspect of. The tubes are thin, and the suspension is light,they have a high failure rate. Sorry, that is just what I have witnessed in the past. I am not saying you have a scope problem, just offering feedback.

As a note there are some VERY expensive scopes I do not think are very good values either.

I would hunt with my MZ I was confident in, until I could buy a $200 scope and new mounts. Something with a lifetime warranty(good value), like a buckmaster and some leupold mounts and rings.

Unless you know of abuse, I would not think the gun had major problems. Yes a wood stock warping can be a problem also, that would be a judgement I would make if I saw it. PVC with sandpaper should work fine to relieve the stock if you decide to go that way, doubt you would hurt anything by trying.
