All the AR s I have pinned together have been fully functional. You do have to de carbonise the actions after 150 rounds, but that's due to the gas impingement action design more than anything else. Stay away from bargain basement components if you want good results. Me personally, I currently only own one, but I have three different styles of barrelled upper receivers, mission or mood specific, so to say.
