Had a student today with a CAR17 have a jam with a round sticking out about half way out of the chamber. it took a good 5 minutes to get it pulled out and out of the chamber comes a peanute butter egg candy wrapper stuck about 3" into the barrel. They guy had put his first mag in his pocket and the first round in the dark grabbed the wrapper and it went home with the first round.... i don't know what to say about that... it was pretty epic.
