Hi, I had been enjoying the shooting sport for quite a while. I always want to find out more about the technical side of the operation of firearms. I am planning to take some gunsmithing course as a hobby. Something I can take at home at my desire pace. I come across this American Gunsmithing Institue (AGI) online and I wonder how good or how reputable they are? Has anyone of you folks taken their course(s)? What do you think about them? What would you say their pros and cons are? Any input will be greatly appreciated.
