You guys actually clean your ARs? Mine only gets cleaned when I get really bored.
4-6 drops of SLIP 2000 EWL on the gas rings every 500 rounds or so (or when I get bored), and the occasional 2-3 drops around the cam pin. Rack the bolt for about 5-10 seconds to let everything work in, then go back to shooting it. Replace the gas rings when needed, and keep going. I'll occasionally run a bore snake or the OTIS kit through the bore just to knock loose some grime.
I have had several ARs that have run for hundreds or thousands of rounds without cleaning, and only a few drops here and there of SLIP 2000 to keep them lubed, and I have never had issues. Currently running an LMT 10.5" upper with BCM BCG and an AAC SDN-6 can that way, and still not having any issues except for the upper being overgassed with the can.
