So, because I think it could be helpful to anyone considering buying a Mesa, I'm going to keep this thing going. No response to my email sent two business days ago, so I called. The gentleman I spoke to was very polite and cordial, and said "send her in so we can take a look." OK. Optics off, rifle boxed up. Finally got a return email this evening, so she's headed back to Utah. Fingers crossed we can get whatever is going on resolved, because excluding the most important part, the rifle is a really awesome setup.
