CQC calibers
Just about to finish my first build which was an entry level knock around 16 inch 5.56. I'm just waiting for the barrel to come in. Because of the uber wait times on everything I've decided to get started early on my next build. Gonna go the SBR route an was interested in playing with a fun caliber. Seeing as how a SBR would be mainly for CQC, what's a nice big caliber that would perform well in CQC situations but still be useable in an AR build? Any suggestions welcome.

5.56X45.
There are many good reasons why the military uses it.

with a 12" or so barrel, and a 7" or so sound suppressor, using the deep penetrating Nosler Partition softpoints, the 223 does fine, and it retains the ability to use GI ammo, reach 1/4 mile, and use the .22lr conversion unit. the other calibers give up these major advantages, for no real offsetting reason to prefer them.

I agree 100%. When deviating from 5.56 you really have to be able to justify the change. Many good larger calibers have been mentioned here but how do they work any better than 5.56 for clearing a room? Maybe you have reasons but I don't see them myself.
No doubt there are lots of good applications of those calibers but for CQC?

Agreed. 5.56 does it's best under 200 meters terminally (in side tissue) round fragments real well plus 2 shot under one second on target will shock the central nervious system therefore incapacitating your target. Head shots work well too

8" or 9" 300 BLK.
You won't go deaf & be temporary blinded if you have to use it inside without a suppressor. It uses standard AR mags with no loss of capacity. I also like the 7.62 sized holes it makes vs 5.56.

We did a little testing with the 300 Blackout in Texas in November. Shot regular loads and even loaded some special rounds and use a suppressor on it. To say the least it was very impressive and fairly quiet! We also shot some coyotes with it which worked out well. It was basically designed to be used on SBR Platforms with Suppressors. Just as a note it also seemed quieter in our testing to even run the 308 Suppressor on the 5.56 rifles.

Hey Sniper, can you expand on this, I'm not sure what you mean.
