This clear feed cover replaces the bottom plate on your cyclone feed system. Please note that this is not the entire cyclone feed, only the bottom plate. Look at the related items below for the clear cyclone body from TechT.
The clear plate allows you to see the inner workings of your Cyclone while keeping the tactical black appearance of the Cyclone. It is a pretty cool mod that will make your marker standout from others.
As a practical use, this cover lets you quickly identify any problem inside the Cyclone.
