How are those M85s working out? I'm looking for something I can run hot with cheap ammo. What I've read points to extractor failures.

I have a .223 and a 7.62X39. No problems with extractors but the mechanism kinda clicks during bolt manipulation. After the guns are fired, upon bolt lift something clicks like the trigger resetting itself. It hasn't been a problem so I havent looked into what is causing the noise. Just a bit disconcerting.
