Hey guys. This week I got my hands on the SBR of PCP airguns: the Rapid Air Worx Micro Hunter. This compact beauty is everything you would expect...minus the power. The websight said the power is adustable. You can certianly ad a longer bottle. If anyone knows how to adjust the hammer spring to get 890 FPS, please let us know! I did not have time to explore the tuning thing. Happy Thanksgiving weekend! -Nate
