Meade 8.8mm with loose retaining rings?

I've been comtemplating one of these for a while, and have an opportunity to get one at a decent price, but there's a catch. The seller tells me that he noticed that it has loose retaining rings that allow the optics to not seat properly. He claims its an easy fix, and that he had to do it to another Meade 8.8mm UWA he owned.

Anyone ever heard of this? Is it something you would attempt to fix yourself?

BTW, it's the Series 4000 UWA model.

You can simply unscrew the barlow element out and use a pen tip to tighten the retaining ring. No problem I'm surprised he even mentioned it rather than just doing it himself.
