Guys, I had my ar out at the range and it tried to load a cartridge as the empty casing was ejecting. It did this one time and I cleared it. I went to fire the gun and it jammed. This time it really jammed. I can't get the bolt? to pull back and eject the round. It is completly jammed. What can I do here? I got the lower off the gun, but still can't get the bolt to move back...it won't close all the way either...it is completly fucked. Here are two quick pics I snapped.
