Looking for good books on gunsmithing. What are some good ones you like or ones you don’t like. I’m fortunate to live close to John Langley here in southern Ohio and have just started going out and working with him and having him teach me. He has built all my rifles over the years and I’ve known him a long time. He mostly does BR rifles and 1911’s which are my same interests as well. He is getting up in years and doesn’t know how much longer he will do it and I’m buying all his equipment once he decides to hang it up and I’m a complete newbie when it comes to machining. Any help is much appreciated
