Ads AR and Hard use?

[pistolman1974]

It seems like they have been out a while and looking to purchase one sometime before the end of the year. This will be my SSHTF.

Has anybody used them in less than desirable conditions, classes, or just shot lots of rounds without cleaning.

How reliable have they been performing?

I wanted one for T&E (for hard use as I can break an anvil) but since I'm not LE they won't send me one.
