The Blackleaf Airsoft Custom Motor Control Unit (MCU) kit allows you to hook up your box mag to the HPA Engine (Wolverine or Polarstar) so it will automatically wind when the trigger is pulled. There is also a variation for the Polarstar FCU and the Wolverine FCU (due to different connection ports on the FCU).
The kit comes with a "Y" power adapter so you can use a single battery to power both the FCU and the box mag, if you choose. The Wolverine MCU kit comes with an extra connector to solder onto the Wolverine FCU, and replacement heat shrink wrap (when working with the Wolverine FCU to attach the box mag connector, proceed with caution and at your own risk, we cannot be responsible for any damage done to the Wolverine FCU if you attach the box mag connector, please seek out an qualified and experienced technician for the modification).

While the sport of Airsoft is designed to be enjoyed by all ages, ignoring proper safety practices can turn a day of fun into a tragedy. Todays modern airsoft guns are capable of firing a BB at velocities that can and will penetrate fabric and skin, causing serious injury. Always wear "Full Seal" eye protection and observe proper weapon handling practices such as keeping the weapon on "safe" and cleared with the magazine out to prevent accidental discharge. REMEMBER!! Safety begins with the shooter!!
