We have 4 kits to upgrade your marker from Gen4 to Gen7. If your logo plate has the metallic color - your marker is already a Gen7 with the latest internal parts and upgrade. Some Gen6 versions have the new part #35 Flexi-Air Adapter, if you already have the new part #35 you just need to get kit #1 or kit #2. Only get kit #3 or #4 if you don't have the new #35.
