My brother in law has an Electra and when you shoot it, it may shoot 10-15 times and it will quit. it is still cocked, and when you pull the trigger you can hear the switch and the electronics it just won't trip the bolt. It does this with the eyes on or off. Once it stops shooting you can wait a few seconds and it will shoot a couple of more times before it does it again. Any help would be greatly appreciated. Thanks in advance.
