i have a ca m15a prob. when i first got it, it worked fine. i was shooting it and suddenly jammed. once i cleared the jam it will no longer shoot out any bb's. I checked the mag and it seems to be working fine it has pressure when the knob is cranked. If i leave the mag in and open the top reciever (take out the back bolt and open it to look at the inside) all the bb's come flowing out which leads me to believe that it is not a defective mag. An suggestions from anyone. The piston that actually hits the bb seems to be functioning properly when i pull the trigger and the upper reciever is off it moves back and forth.
Any help on this manner would be greatly appreciated.
