You got that right. I was a Royal Pain in the A$$ about part swapping. It finally got through my thick skull that these people were just doing what they wanted with their possessions. I predicted that all of these corrected guns would someday be out on the market with no one the wiser. The standard reply was " When I sell them, I'll put all of the old stuff back on them". Well that didn't happen, but it's none of my business anyway.
