Hoping Adams has tested this combo. I would think most owners of the new 300BLK 9.5" are gonna throw a can on it.
The piston rod on the previous piston AA uppers needed to be modded/milled just to get it over an AAC 51t.

I'm really hoping these two will be compatible. Taking a leap of faith as I have both on order through my  III dealer.
Would be an expensive mistake if this doesn't work.

Their 300BLK uses the XLP gas block and its not a pull through the front design. In order to get the piston op rod off you have to remove the gas block.

The lightened carrier helps as well.  The subsonics with the reduced powder charges need as little resistance as possible, and mine (a build with the XLP and lightened carrier, fyi) cycles everything fine.

As mentioned, the XLP is not a pull through system. you can remove the selector for cleaning, and on a pistol length gas system you will have more than enough clearance over any type of suppressor QD.

So, you need to take the gas block off anytime you clean the firearm?  I'm a little confused.
