Time for some heresy. I've owned a loaded M1A since 2002. I am up to approximately 11,000 rounds through it. Only recently have I had any problems with stoppages and it was reloaded machine gun brass which decided to have case separation issues. There has never been a stoppage with the 8,000 rounds of Portuguese surplus. There has never been a stoppage with the 1,000 rounds of South African surplus. There has never been a stoppage with a few hundred Malaysian surplus. There has never been a stoppage with a few hundred Lake City surplus. There has never been a stoppage with a 100 or so Australian surplus. The closest I've come to taking the rifle down was to replace the stock with a GI fiberglass stock and occasionally checking headspace. It has never been lubed, greased or cleaned. The gas plug still moves freely when I pick it up. The headspace is still good. It was sold with 1.632" and is still between 1.630" and 1.634". The last 10 shot group at 300 yards was 14" with iron sights and 59 year old eyes. The last 10 shot group at 100 yards was 4" same sights, same eyes. These were with the aforementioned machine gun brass reloads. Portuguese surplus at least used to be better, but I'm running out of it, hence the reloads. I have to admit to taking a chamber brush to it when I get a stuck ruptured case. This has occured perhaps 10 times. I know this makes me a bad person, but consider it a torture test on the "crappy" Springfield Armory rifle. And to make some of you, myself included, cry, I bought the Portuguese for $139 a case. I have 2,000 rounds left.
