Dont know...i've never run the switchblade on an Orion (its brand new) but just holding it up there it will work with one screw/bolt.
A TSI flexfender would work better on it, but I dont have any extras.
Also, it only takes a few minutes and very little skill to make your own flex fender
.
For $20 more ill make you one for it... but for that price you might as well buy a true spring steel flexfender from TSI.
