Just over 2200 on my Colt. Just light lube, trying to beat the hell out of the Fail Zero bcg I am running in it. Will put another 600 in the morning.

My N4 Basic went over 2000 yesterday lubing every 400-500 rounds with KG-4 Oil. Not a single failure and still very accurate.

Around 4200 rounds is the average when using Wolf and lube without a malfunction (stuck case) in 4 ARs, 2x6920's, Sabre Defense middy upper/Colt Sporter lower, and a LMT MRP middy.
Pat Rogers' Filthy 14 stood at 41,520 rounds and counting last month.
I'm up to 1,197 on a BCM without cleaning, and didn't add any lube through the first 1K, just to see if it could take it. No issues so far, nothing.
On my 6920 I can't recall ever cleaning it. I keep it lubed but it's never had a problem. So I'd figure it's a pretty high round count in the 10,000's.
A long time ago I owned a few others and cleaned them routinely.
AR's will run for a looong time so long as lube is used at regular intervals.
That said, cleaning is important to effectively evaluate parts for wear etcetera.
For me, I've run FZ's without either cleaning or lubrication for beyond 2k rounds on multiple occasions simply out of neglect. I really don't see much of a warrant nor reason to intentionally run over 1k without at least a cursory cleaning and inspection unless T&E'ing something.
Whenever I build a New One from the ground up,,I like to run at least 300/500 rds through it before I do anything ! I do lube it from the start though !! I think the most I have run is around 1K,,maybe 1200,,rds,,,I'm not a fanatic about cleaning my guns,,,,but it starts eatin at me after 7/800,;),,so to make it to 1K its hard on me,,LOL !!!
2980 in a Colt 6920 with minor lube intervals.
