I've had one problem, with a brand new M4. The barrel was loose. I turned it back into the Armorer, got a new one. No problems. I'd shoot it, pull the bolt carrier out, wipe it off with a rag, take the bolt out wipe it down, take that same rag, swab around the inside of the upper receiver. Apply a good coat of CLP on the aforementioned parts, keep her wet, and she'll shoot all day. Repeat every 3000 rounds. Fancy cleaning is for turning it in, or if you have nothing else to do.

Aside from the loose barrel, the only problems I've ever had with the 16 series were a result of not having enough CLP on the moving parts.

I think there are just too many Soldiers that don't get to shoot realistically often enough. Not enough familiarity, and a whole lot of timidity with regard to the weapon.
