Yep, any 5.56/.223 mag will work. The 300 is just a 5.56 case necked up to .30 cal. That's the first benefit over 6.5/6.8. You get full magazine capacity since the case is no bigger. You also don't have to change your bolt. As far as ballistics it's far superior to 6.8 and the only advantage 6.5 may have is in the 400yd plus range but I don't even know if I buy that. There is already more, and cheaper factory ammo for the 300 and it has full Remington factory support. AAC isn't charging anyone royalties, it's an open source design so it should blow the other alternative calibers away.

Is the 300 Blackout and the 30 Remington AR the same cartridge dimensionally?

The .30 Remington AR is based on a necked down .450 Bushmaster.

No the 30 Rem AR is based on a necked down 450 bushmaster case which I'm pretty sure started out as a shortened and necked up 308. The 300 blackout is a necked up 5.56 case and the 300 whisper is a necked up 221 fireball case. The 300 blackout and whisper are pretty much interchangeable, most barrels can handle both since the chambers are so close. The benefit to the blackout is for reloaders since you can modify 223/5.56 brass. Remington is offering multiple factory loads for blackout as are a few other companies. Hornady is offering factory 300 whisper.

The .450 Bushmaster is based on the .284 Win. and has a rebated (.308 size) rim.
