MAC: How many rounds without cleaning or lubrication before a DI AR15 stops?

Ammo is a whole lot cleaner now than back in the day. Wrong powders were the initial fault of the M-16 DI jamming under combat conditions when first issued. Cleaning kits weren’t even supplied.
Reformulation of the ammo and training to properly clean the action cured almost all of the problems.

That's pretty impressive. He's running that gun pretty hard and it doesn't seem to mind in the least.
