AGM HK416 Gearbox sticks
I have an AGM HK416 which doesn't fire. The piston moves back partially and then just stays there, pulling the trigger results in a motor pushing against an immovable object type sound. I've downgraded the spring in case the springw was to powerful for the motor and i've stuck in an EG1000, still same thing happens. I've had the gearbox apart and back together again, i'm pretty new at gearbox maintenance but i sort of know my way around them and i can't see anything wrong.
Help!
