What's helpful is knowing in advance that Volquartsen may have screwed up even the replacement parts, so now I know to measure it to confirm it's correct before tearing the rifle apart to install it. Without jayfl77's report I would have assumed Volquartsen's competency in providing a functional replacement part and been surprised and frustrated at discovering yet another problem with my rifle laying disassembled in front of me.

It's only because of this thread that I knew to check the extractor before installation the first time around, letting me find the issue early and get the replacement part on the way before the new gun even arrived.
