Imagine a car that within a few minutes you could configure it to race on a track and ten minutes later have it racing the Baja and 10 minutes later have it doing rock jumping. Then it could also be configured into a boat or a space shuttle. You could take off 2 wheels and make it a bicycle or make it a motorcycle drag racer.
It is the most configurable rifle in all of history. If you added up all the configurations possible with all the possible accessories you would have a number larger than the total number of atoms in the universe (really).

.223 Remington - Original AR-15 caliber: .223 cartridges may function in a 5.56×45mm rifle, however 5.56×45mm cartridges can produce excessive pressure in a .223 rifle.

You know what else? You can use the AR15 as a crossbow. It can launch soda cans. It can be made into a shotgun, grappling hook launcher, a pump action rifle, a bolt action rifle. You can bolt a chainsaw to it. obscene anatomy parts are accessories. You want to make a pink one that has an anatomically correct nut-sack grip? Sure! God Bless America!
It can be every color of the visible spectrum. There are probably a 1000 different variants of just one grip to put on it.
I could go on but it is literally the do-everything rifle plus more
Awesome response. Appreciate it.
