Ugh, I just received my replacement extractor from Volquartsen. The original OEM extractor measures .06" on my calipers. The first Volquartsen extractor I bought (from Brownell's) for my newest rifle measures .071". The replacement extractor Volquartsen sent me measures .07".

The Volquartsen extractor I bought from Joe Bob Outfitters for my other 15-22 fit without any issues. I'm not going to take the rifle apart to measure the thickness of that part, but visually it's clearly thinner than the two extractors currently sitting on my desk.
