“Uuuuummmm...cant one already buy an ar platform chambered for any number of calibers? This isnt a valid selling point.”
The standard AR gun is a DI gas system. Some shooters don’t like corrosive milsurplus ammo through those type of systems because it blows the dirty leftovers all over the internals.
Almost all my guns are AKs so I don’t care what kind of ammo I shoot.

What you say is true, but retreading the article this is also a direct gas impingement action.
7.62X39 shooters, read and heed:

The main reason some folks will like this is because it uses AK mags. The big problem with previous attempts at a 762x39 AR is mostly due to magazine issues related to the shape of the tapered cartridge. Because of the taper, mags have to be curved and with the common AR lower, the mag can’t be curved enough and still be able to be inserted into common AR mag wells.
On top of this, so much material has to be milled from a standard 556 bolt head to accommodate the x39 casehead that it causes premature bolt failure. That’s why cmmg went with the bolt that is used in 762x51 AR rifles.
