For the record it did shoot alot of ammo before it needed it, but it didn't go all day without re-oiling..
After a ~1000 rounds, I need to apply more. That's way more rounds than a load out. It's a carbine, not a SAW. A vastly over rated problem but it is a good question. With a piston, the oil still needs to be applied due to the amount of carbon blowback from the chamber while running suppressed as evidenced by my buddy have his rate of fire becoming just as sluggish under the same conditions that day.
As an aside, I keep a small bottle of machine gunners lube in my ACS. It's a non issue for me.
