Look at it this way Semisane... if that scope fails from water, it would have failed out in the field. I am never gentle with my optics. I don't mean to imply that I abuse them, but why would you handle them with kid gloves? I managed to break one Thompson Center 1x32mm (not intentionally) by basically cleaning a rifle and not being careful where the water spilled.
I should note... Thompson Center replaced the scope no questions. All I had to do was mail the old one in and they mailed me a brand new one.
That is with the quick release mounts. So far it has been holding true.
