A rotation mechanism is used to turn a revolving cylinder on a revolver blaster. In most older blasters, the rotation mechanism is spun by the trigger, which is why triggers are slightly harder to pull on older revolver blasters. However, in newer blasters, the rotation mechanism is spun by the priming mechanism, or upon firing the blaster. Other than to relieve force on the trigger pull, these mechanisms were most likely added due to the increased popularity of slam fire, a feature that would not be possible on older designs. On revolver blasters with a cylinder that can be dropped, the rotation mechanism has a ratchet, that if pressed on, will drop the head of the rotation mechanism. This allows the cylinder to be dropped.
On non-revolver blasters
As Hasbro patented the Intelligent air restrictor system, other companies such as Buzz Bee often resort to adding internal rotation mechanisms into single-fire blasters with multiple barrels. Blasters like the Ultra-Tek Wizard have an internal rotation mechanism that redirects the airflow to different stationary barrels.
Sanding down the rotation mechanism's head, and adding glue on it can increase reliability for it, and will also lead to less misfires. However, this modification will stop working if the user turns the cylinder manually.
