So I was thinking, there is the never ending debate about reliability of the AR platform and some claim that they are prone to jamming if dirty while others never have an issue. This thread will NOT be a vs. thread! My question is, for those people who have experienced jams. Most of the jam types that I have seen look quite easy to clear, like double feed, failure to fire, etc. These types of malfunctions seem to be easy to fix and get back into the fight. So my question is what kind of jams have you experienced that permanently took your AR out of commision (hopefully at the range and not in action).
