I was originally trained by 3 Master Gunsmiths and Firearms Designers and thought that my training was fairly complete. I was truly surprised by what I further learned through Robert Dunlap & teaching. His teaching methods are direct and fully explained. Everyone at AGI has been very helpful and courteous every time I have called. Its reassuring to know that people still care enough in customer service and the actions of their company to help out in any way possible.
