Re: ar 223 barrel life
I'm far from an expert, but I have a 10 year old AR that is somewhere around 4,000 and doing real fine. This with a steady diet of "warmer" 77gr. loads. This barrel has never been "hot", which might help. I'm sure you'll get lot's of opinions, and I'm curious myself.

i think the army says that the service life of a barrel is 10k rounds. i don't know at what point the barrel becomes less accurate.

Re: ar 223 barrel life
depends on a host of factors, especially how you are cleaning it. FA usage, etc. everytime I see someone use the army cleaning rods with metal jag and no bore guide I cringe. Approximately 10,000 rounds sounds right if you are taking care of it. We take them routinely more than that but these are 2+ moa 14.5 carbines.

Re: ar 223 barrel life
It really depends on type of steel and bullet. 10K for M4's as others mentioned is the official number (though this probably has more to do with supply chain logistics and accounting rather than something real). I would estimate 4-5K on stainless (similar to .308) before you see a significant drop-off in accuracy. But there are several reports out there of people beating the hell out of stainless .223 barrels then shooting sub-MOA groups with them. I know Steve from ADCO posted some stuff on a few other sites. It also seems that the long/heavy for caliber bullets, like the 77SMK, etc seem to burn the throat a little quicker---though I'm not entirely convinced 50gr's at 3200+ FPS are slouches in premature wear.
