Simple, to fit an AR magazine.
Those short, fat boiler rooms get it done in that platform.
Also competition bolt guns are proving that the design is worthy.

I've no interest with a .473" or greater boltface on a '15. Go AR-10 of course and you've 2.800" or better COAL to work with.

That's the allure. The Grendel and/or SPC based 6mm's strain to reach 2800 which isn't bad. The 6BRX is over 3000 with a 20" barrel and will feed through an SPC magazine. This is fairly new, there two firms offering 6BRX for AR15, BR Armament Technologies and AR Performance.
I like the AR Performance 6BRX bolt/BE system better than what BRAT offers (Olympic system).

AR308 is a different animal. I would probably want to launch 6.5's out of that beast.
