I have a Marlin XT-22, I love the gun but I don't like the 22" barrel. I would like to shorten it to around 18". My question is what is the best way to do this? I saw a recent thread where a hacksaw was used. I do have access to a lathe and someone who can run it better than I. Also is 18" a good length for a .22 barrel? Thanks in advance.
