Chosen Solution
I had my strong arm for a while and I can’t figure out why when I shoot it the barrel won’t turn and also it creates a loud sound when I shoot it. Very rarely would the barrel turn when I shoot, what should I do?
It could be that the gears are slipping or worn out
Mine was doing this, and it turns out that the gears were fine, but a screw post that holds the gear assembly together had split such that the assembly was slipping. Attempting a repair with epoxy, but expect to have to find parts somewhere, or build a new mechanism.
