I have an experiment going. My Saiga .223 has never been cleaned. 2 years and about 3000+ rounds. I have used a rag to wipe some of the gunk out of the reciever and dump some oil in it every use, but that is all I have done to it. I have never, and mean never, had a FTL or FTF. Lucky i suppose. That rifle is an absolute champ!
