"To start off I bought this KJW hop up spring and all the other little bits and pieces needed to make it a working piece all except the rubber bumper. Now I got two of each why you ask? So I can add the newly built hop up chamber into both my WE M9 Cutlasses. But many will say that WE and KJW are not hop up compatible as the WE M9 has a proprietary two piece Hop up and barrel. Well good news is I tried and successfully installed and tested the hop up and it %100 completely works and actually has hop! No modification needed unless you need the rubber bumper (located in the front of the Hop Up chamber) So with this I leave that magical answer of how to get rid of that old and useless WE M9 atrocity of a hop up chamber and add a better VSR 10 compatible hop up chamber. *For actual proof look up airsoft teching Q&A on Facebook Pedro Antonio Sanchez.
