Out of curiosity, why you interested in that blaster?

Not working meaning not revving? Assuming battery is ok and mag is inserted, and jam door closed, my main suspect is the rev trigger 'pusher' is misaligned... So when you pull the trigger, it didn't push/on the switch.

did the last battery batch leaked and cause oxidization in the terminal? that's my usual issue with the stryfe. use contact cleaner or silicon spray.

another culprit, as mentioned, are the locks. usually it's the lock that checks for inserted magazines. bypass with some cardboard.
