Basic rifle/firearm information on Book/DVD/Video?
I began shooting roughly two years ago and while I have gotten a fair bit of trigger time I have not (shame on me) really learned how firearms work, how the models differ, etc etc. For example, what does it mean that an assualt rifle uses a gas system? What is the internal difference between my favorite 1911 and the glock that I nearly blew my toe of with? Etc etc
Can anyone recommend a resource for someone who is NOT familiar with the mechanics of firearms that lays out the basics?
