This upper has been fine so far. No lube added to date, but not that many rounds down range yet either.

I run suppressed a lot with dirty Russian ammo. I use whatever lube because it actually makes it easier to clean because all that dirty shit get caught up in the lube amd I can just use this process to clean:
carb cleaner -> scrub -> wipe ->carb cleaner -> 120psi air compressor -> lube. Takes 15-20 minutes and I'm good for the next 500-ish rounds.
Mine isn't. I feed it the same thing I feed everything else, 5w30 motor oil, then wipe dry.
Mines sitting here broken right now. They break like anything else. Great guns. Lets not pretend they are perfect.
The fun part about them breaking, is that if you need/want to repair it using KAC components, you're either going to be waiting a long while for a replacement to get sourced, or you're going to pay out the ass on gunbroker.
Probably contact from the bolt carrier plus off-axis tube? I’ve seen several examples where I’d have been concerned about prolonged wear due to the tube not being centered in the upper.
Session 3 is now added to the initial post.
Cheers!

Very likely yes. I still love the gun, but i hate that people pretend they are perfect. Always. Anything man made can break. Still an awesome weapon (and pinnacle of ar15s imo)
Perfect? No
Just one of the best built ARs on the market, with an excellent track record.
I had a buddy’s CQB blow up while shooting factory new Norma ammo and KAC told him to fix it himself, they wouldn’t cover it.
Meanwhile I just ran my CQB through a shoot yesterday, 250 rounds in the sand and dirt and didn’t have a single malfunction.

Maybe slightly.
I can grab the lip with a toothpick or a knife.
It hasn't been a problem, but might be worth polishing down now that I notice it.
Half of the accuracy testing is posted.

It was a nice write up, the results were as expected.
I cry about KAC on this forum but to give them credit, they make a quality product. When I have noticed differences in their uppers is actually on the longer barreled stuff. Their tuning of gas/buffer/spring to make a military reliable rifle that shoots soft (relative to milspec) is pretty awesome.
Good luck with the house, hope you enjoy it.
