I've seen this be so severe that it's actually melted the selector plate, and deforming it. I've also seen it melt the plastic over the contact plate and push the lower "finger" out of the way, breaking contact and making full-auto fire intermittant or impossible.
If you pull the mechbox out and look at that point, you'll see if this is the case.

Hmm. That would make sense. I noticed while checking my shimming I noticed the selector plate seemed 'bubbled out' and thought that somehow the sector gear bushing was pushing it out...double checked and it was shimmed fine so I figured nothing was wrong. I have yet to tinker much w/ the trigger assembly and selector plate so I'll have to take a gander and see now.
Mac, is there any specific cause of this selector plate melting or anyway to prevent it?
