How many rounds does the Colt factory put through a typical civilian or LE AR during a test firing prior to shipment?

I know from the tv show amreican shooter when the showed the Colt factory.
When they were shooting revolvers they shot 6 rounds and 1 of those
rounds was a prof round that was 10 pecent hotter. They did not show the AR
in that show so I only Know about the revolvers.

the Mil-Spec that is downloadable from the front page of this site (both rifle and carbine) says that functional testing is done on a statistical basis.  Example:  for a given production lot, if ten weapons in a row pass a given test, then only one out of ten of the balance of the lot are tested for that function.  Although the Mil-specs are addressing full or burts auto weapons, I'd guess that testing on LE semi auto weapons follows the same general statistical format.  I also assume that proof testing is done 100%.

M16/AR-15 test fires are one (1) 30rd magazine of .Mil M855.

L.E. weapons - Lot tested to meet Mil-spec.

.Mil weapons - Each Rifle is tested to meet Mil-spec.

Proof firing is a seperate process from test firing. Every barrel is proof fired with a high pressure round.
