The Honey Badger HPOP's are doing GREAT! We are finding ways to make them better all the time. We are still researching and testing with the Senior (big piston pumps) but like Dustin said I am not sure that we will ever get the reliability out of it using a stock housing. We did buy a CNC mill and we are working on a new housing for the Senior HPOP.
Thank you for all the positive feedback and please never hesitate to contact us directly if you ever have questions about any of our parts or services!
