There are many different types of firearms available these days but not all are meant to be fighting guns. When I am with the ATAC Guys or others, we do not participate in the sporting aspect, rather the tactical application. So our viewpoint is prioritized a bit different.

They are built for a specific sporting purpose; while they are great for wing shooting they are a poor selection for any kind of fighting/home defense. That's an extreme example I know so lets define this a little better. A fighting rifle should be semi-auto or select fire, have high capacity detachable magazines, chambered in a military caliber, a flat non-shinny finish and fit into the list below.
A true "Fighting Rifle" should meet the following requirements.
