An AR should be able to run 2000 rounds without cleaning but it will still need some lube every so often. Strange that yours needs a cleaning. Have you tried pulling the BCG and just giving it a quick wipe then a little fresh oil?
Running really dirty ammo like Norinco will require lube a little more often but the rifle should still cycle.
I like rifles like my PWS, it is factory cerekote (inside the receiver as well) which has some lubricating properties so that rifle doesn't seem to need lube as often, I installed a nickel boron BCG in one of my other AR's and it seems to work really nicely as well and needs less lube than a standard BCG to keep on cycling when dirty.
nope I always run good ammo, it has a match chamber though so its tight.
