Yep, that is one hell of a rifle.

Closest I have witnessed was an SLR- Aussie FN FAL- a Warrant Officer was wearing the M60 asbestos glove on left hand. Firing as fast as e could pull the trigger, being hand feed a mag the moment his was empty. The fore end has an alloy protector on the inside. Wood was smoking, barrel was glowing white. You could see a grey pulse travel down the barrel with each shot. Only reason he stopped was we ran out of ammo. No idea how many rounds, his mag changers were quicker mainly due to the charging handle being on the left side. Rifle was still functioning and you could plainly see the drop on the barrel.

Yes it was sent back to the amoury to have a new barrel placed on it.

I would like to see that test with an Israeli Galil.
