May I ask a question? How is the rest mounted on the riser? In that, I mean is it mounted toward the shooter so that the launcher arm can go to almost a horizontal position in the "down" state?

Or if you mounted it forward on the riser, is the the vertical adjustment high enough so that the launcher arm can drop down enough for proper clearance?

Just some thoughts- I have seen people set them up so that the arm never has enough room to fully drop out of the way....
