Reaper HPA Engine

*System requires a 7.4v LiPo battery (not included in package)

The REAPER utilizes the technology from the BOLT and adapts it for the conversion of AEG guns to HPA machines! Now you can use the pure closed bolt technology of the BOLT in your M4, AK, M249, and more! The REAPER is a true closed bolt drop-in HPA engine. It is extremely quiet, accurate, robust, and durable.
