As a further point of clarification, I have found out that Karl and Eric have not been employed at Remington since July 2014. They no longer have any affiliation with Remington.
For what it is worth (which, I guess, is nothing at this point), Eric and Karl were very aware of the warranty issues and urged Remington to deal with these issues many times. However, they had no say in that process. Eric would certainly have handled warranty repairs on existing pistols if he had been asked or allowed to do so.
