Actually the AR-15 ammo would be the .223 - maybe a
third of the way across from the right.
And then remembering that the AR has been modified
such that one can get one in just about any caliber
one wants . . .

Build an AR-15: AR Calibers
http://www.gunsamerica.com/blog/build-an-ar-15-ar-calibers/
In these troubled times where everyone wants to stir up trouble and hate over our differences in appearance, I want it to go on record that I don’t just tolerate diversity, I embrace it.
In my safe right this moment, I have AR-type rifles chambered in .223/5.56mm, 6.8 SPC, 300 Blackout, and .308 Winchester. Of course, .308 is admittedly related to the Armalite AR-10, not AR-15 family. When it comes to diversity, I put my money where my mouth is. As we speak, I’m Jonesing for something in 6.5mm. Not only that, I’ve been begging the folks at Smith & Wesson to come out with an M&P 338, chambered in, you guessed it, .338 Lapua. Why? Because diversity is fun.
