There's a clutch in the rotation assembly that will slip when too much resistance is met. This protects the internal parts and makes the Maverick more durable however it also causes the occasional misfire. Gluing this clutch will prevent misfires from occuring but you can't manually rotate the cylinder while it's not released or you risk breaking the join. If this occurs the blaster will return to normal operation and may misfire again. You would need to repeat the tutorial.
