Wolverine Airsoft has been busy on another project and now they are ready to reveal what its, the Wolverine Airsoft Reaper... "After the success of the BOLT, we decided to use that proprietary technology to give you something new. We have adapted the technology from the BOLT and developed it for AEG rifles! The Reaper is a TRUE CLOSED BOLT HPA system that also has the same Air Saver technology in the BOLT. It can be used with an FCU or Electromechanically."
