Now with the ATF changing its ruling on putting the hand brace to your shoulder the idea of a 10" AR-15 300 ACC blackout just became interesting. That with the hopeful option of adding a suppressor in the future.
But, as I have stated on these boards, I am a cheap bastard. So the bullet options have to be examined. I know the 147gr FMJ would function fine, as would any pointed bullet probably, but what about a 110 grain round nose? You can get those plated pretty cheap.

I have run 110 gr plated round noses in a 16" 300 BLK.
No problems. I don't see that it would be any different in a 10"

I'm developing a 7 1/5" AR pistol in 300 Blackout with a suppressor. Coated cast bullets are costing me $30/250. Since you're shooting subsonic you'll want heavy bullets to maximize energy given recoil is never an issue in the AR. Save the jacketed 110's for your super loads.
I don't have a shoulder brace. Resting the buffer tube against my body steadies the pistol better than holding it off hand. A shoulder stock would be better. Pistol buffer tubes are different than rifle's.
I may be cheaper than you - paid $360 for my new complete AR pistol off of gunbroker.
Developing this pistol has been the greatest reloading challenge I've ever encountered. Balancing AR function with sub sonic loads while striving for minimal sound signature is a whole new world for me.

Plus I figure the bottom will drop out of the price once they are removed from the NFA. They are too simple to cost that much money.
