The inner barrrel is a 6.03mm replacement for the stock barrel which comes in your WE pistol, and due to its length will increase the FPS of your pistol. The suppressor included in the kit is a mock suppressor, designed to hide your extended out barrel but can be used for purely aesthetic looks. This upgrade is perfect for your pistol if you want to increase the output of your WE brand pistol.
