This is one I thought I knew the answer to, but the more I hear, the more confused I get. What is the difference between M1 Garand and M14 extractors and can I use an M1 Garand Extractor in an M14 and not have any problems? I have found some new M1 extractors at a good price and would like to get a couple for my M14. Is this a good idea? Thanks.
