A US gun magazine (SWAT, Oct 2010) had an article of a long-term test of a Bravo Company Mfg. AR carbine. Pat Rogers is a retired Chief Warrant Officer of Marines and retired NYPD Sergeant. Mr Rogers is the owner of E.A.G. Inc., which provides services to governmental organisations and private citizens. He and his colleagues received the carbine in late 2008 and put it into service shortly thereafter.
The bolt was wiped down at 6,450 rounds. The extractor spring was replaced at 13,010 rounds. In June 2009, two bolt lugs broke at 16,400 rounds. Apparently, that's within normal parameters. In November 2009, they had several failures to extract at 24,450 rounds. The shooter gave the carbine a field cleaning and replaced the extractor and extractor spring. At 28,905 rounds they finally cleaned the rifle properly.
The point of the 15-month exercise was to demonstrate that an AR build to a quality spec will run more reliably for a longer period of time than a hobby gun. They ran a number of rifles to over 15,000 rounds without cleaning or malfunctions as long as they were kept well lubricated.
It just shows how tough the AR platform can be.
