This modification will make your semi-auto "only" Cybergun/KWC Mini UZI BB Gun into a full auto capable 4.5mm BB machine gun. From the factory the full auto switch position (Far Left "A") is disabled but the full auto selector position is visible. The actual full-auto functionality is still present in the Mini UZI but has been decommissioned by the simple means of blocking the selector switch from being moved to the far left full-auto or "A" position. This full auto modification will show you how to disassemble the Cybergun - KWC Mini UZI BB Gun and remove the small plastic selector switch blockage so you will be able to manually switch between semi auto and full auto modes. This modification takes about 15 minutes to complete.
