Heads up! There's some .222 extractors that just landed on ebay. If anyone can point me to a 721, .473 extractor, I'd be VERY grateful. Have a great one, y'all.
I've corresponded with the guy. The .515 measurement is on there because of my question. The gentleman is a "handgun" Smith doesn't know much about them. He's probably putting "used" because he doesn't know. He also has no packaging telling him part number. Based on the measurement I'm fairly sure they are for std bolt face?
