3. have you cleaned & lubed lately?
4. check that the gas tube/gas block/ is connected and intact
I've shot several Brands of ammo. My only complaint has to do with the rust-inhibitor coatings.

1. Ammo-mine will shoot anything. If there was ammo it wouldn't shoot, I would fix my gun so it would.
2. Gas rings-good iidea. I replace mine after every trip to the range. Only$0.35 each, so that is cheap maintenance
3. I am a lazy @$$ when it comes to cleanup. I drop my bcg in solvent and use brake cleaner for the rest, then put a little lube on it and call it a day. I got other things to do with my time. My gun shoots when I want it to.
4.Checking gas tube/block is a good idea.
As others have posted, you might want to check your buffer/spring setup. I know of a few guys who have a different buffer/ spring setup for practice ammo than what they have for competition ammo. If you have an adjustable gas block, you might also want to change your setting.
