I don't think planet made a high rise for the bushy as an aftermarket upgrade, the high they currently have is probably the newer rises that ICD is sending on the bushies. I you want a high rise call either www.animalpaintball.com
for the sonic high rise. I don't think Check it makes theirs anymore, but the sonic is better anyways. www.paintball-paradise.com
sells the stock high risers from ICD, but you have to call them or contact ICD on their website. hope this help.
