So I don't think people realize how durable the AR platform is in general. Again in working at a indoor gun range I've seen a Delton that went 16k before rounds started keyholing and it was clear that the barrel was burnt out. Now this is in pretty ideal conditions with people who can do minimal maintenance, but it makes sense when people talk about their PSA or whatever brand rifles that probably don't stick to "Mil-spec". And the conditions a PD rifle see's are probably much more favorable to some soldier on the frontlines. So an M&P15 that is shot minimally, and is rarely exposed to harsh elements might last a while.
Dr. Carter G. Woodson, “History shows that it does not matter who is in power or what revolutionary forces take over the government, those who have not learned to do for themselves and have to depend solely on others never obtain any more rights or privileges in the end than they had in the beginning.”
