AR15 gas rings ?

[Usmc0844spare]

The simplest and most common way to check if gas rings need replacement, with a clean bolt and bolt carrier, insert the bolt into the carrier opening. Extend the bolt into the unlocked position (without the cam pin) and stand it on its face. If the carrier collapses onto the bolt under its own weight, then you should replace your rings. Replace all three at the same time. Another quick note on gas rings. The myth that gas rings must be staggered to prevent the splits from aligning and causing gas leakage, is just that- a MYTH. There is no reason to do so. Yes, I know the USMC manual calls for it, but its still not needed.

This. Aligned gas rings do not matter.

As to the question of lubing them, sure, I do, but only for "why the heck not?" reasons. I leave my rifle pretty wet just cuz it stays locked up in the garage for extended periods. I fear rust way more than I fear under-lubrication.

Hot dang. Thanks buddy, I'm printing this out. Actually, I also printed out the other image on the reddit thread for the lube points on the whole rifle. Gonna print it and put it in my box.
