When I was a kid my Stevens 22 semiautomatic quit extracting. My dad and I took it apart and found the broken extractor. Didn’t have a source for a new one so we cleaned everything and reassembled it and kept the broken part for later. Turns out, it worked great without it so we forgot about the part.
Some .22 autos don’t even come with extractors. The same pressure that blows the bolt back also forces the case out of the chamber.
