I bought a ripper Hi rise and it didnt work for me. im not bashing ripper cause the grip frame is the sh*t. but you have to have a eggolution or sand your hopper to get it to fit in there if you have the newer style so i sent mine back.
the site for ripper is www.cnc-machining.com/ripper
and for a pic go to www.odbo.net
and tank has a pic of his bushy with the silver hi rise i think
hope this helps
