What size and upper are you all running on your 300blk sbrs?

I'm looking for one that's factory built to hopefully avoid tuning.

It's going on a spikes tactical lower. I've also considered a 223 upper but not 100% convinced since I cant use my rugged obsidian on it.
 
I picked up a Seekins factory built 10.5" 300BLK upper on Black Friday a couple years ago. It's been 100% reliable and accurate with every load I've tried.
 
I have one I bought used. It's a KAC upper but the previous owner swapped the barrel for a 10" Noveske.
 
Got an 8.5" blackout from psa last black Friday sale (I think) haven't had a problem yet and it was like $199.
 
I have a 10.5" I picked up from DSG back last year for like $400 complete that runs like a top.

Anything between 8-10" is perfect.

I have the Rguns one AIM ran on special a few times for $199 shipped. Topped with an Aimpoint CompM, switched to a Troy ambi-latch, and installed the gemtech mount as a flash can when not suppressed. It cycles everything from my powder puff bolt gun subs to 110gr supers with no issue so far...
