CA36 won't fire
 

Stock CA36 running 8.4v 1100mah NiMH. Was shooting a locap on semi when it just stopped shooting. Everytime I pull the trigger, I can feel something inside pushing forward slightly then springing back with a bit of force. Same thing on auto. Anyone have any idea what could be wrong with it?

Nm, the battery was low. Man, CA + NiMH might not be the best combination.
