>Like a round getting stuck in the chamber at the critical moment where you seize the turn and take the shot. :/ Heard about a lot of that coming out of 'Nam when the M16 was first widely issued. It was issued to US troops and they were told it was "self-cleaning". Hundreds of American men were killed or maimed because of this bullshit. The US government quickly distributed pamphlets with instructions on how to clean the M16... but a lot of American soldiers would abandon their M16s for more reliable weapons looted from the corpses of VC/NVA. That is a terrifying thought. This is why we spent an obscene amount of time learning how to clean our weapon systems in the Marine Corps. A tiny fleck of rust on the wrong part of a rifle could be the difference between "You shoot the bad guy" or "You expose yourself, pull your trigger, get spotted and shot before you even realize what happened".
