G.I. is a military term that means Government Issue.. Many older veterans will refer to current and former military members as GI's and it's the origin of the term G.I. Joe. Or. GI can be an abbreviation for gastrointestinal, referring to the human digestive tract.
The M in military designations stands for Model. What the AR in AR15 stands for has been the subject of more than one discussion on this site. Originally, I believe, it was supposed to stand for Armalite; the company that developed the piece. When Colt bought the rights to build the gun, AR sort of started to mean Automatic Rifle; so take your pick[:D]
