One of the things I like about the NRA Range is that they will let you mag dump. Rapid fire a lot of ammo continuously. Even a mag dump on my AR-10B. Mag dump 12 mags, in a row, non stop in less than 5 minutes.
The test was intended to see if it would have any failures when it was really hot. When the Killer Robot Uprising hits I wouldn't want a problem.
The good news is that 240 rounds shot quickly had no failures at all. The accuracy of the rifle did not degrade at all. I was surprised that my own accuracy didn't degrade after getting hammered 240 times.
The bad news was the fore grip became so HOT I was unable to touch it at the end of the test. Not just the Barrel, the grip. The first and last mag was done from a sandbag. I mean HOT. This was not good.
