How often do the rings go bad?

Thanks in advance,

They don't usually. But the gas key sits on top the bolt carrier and can come loose unless you stake the 2 bolts in place. A factory rifle is done already but if you put one together yourself you may need to do it.

The 3 rings on the bolt hardly go bad unless they are broke. But they should be set at 120 degrees apart from each other to prevent gas leakage. They are just like the rings on a piston so if you oil it you could go the life of the rifle without changing them.
