Query: NRA guide - a path for learning

This is a fantastic book. I found it both interesting and informative. I enjoy having technical text such as this, and find it does help me find areas for caution. If you are the least bit uncomfortable with the content in terms of doing the work, DON'T, seek a professional gunsmith and not just a friend with a drill press in his basement.
