I am not going to argue what the definition of sporting is, it is different to everyone I guess. Many shooters don't hunt but enjoy punching holes in paper targets or participating in 3 gun competitions, etc... To me the AR15 is no different from any other semi automatic rifles out there... I just always thought that in the confines of a home, a rifle or a shotgun is a bit cumbersome and a handgun is much more nimble in tight quarters.
