so I finally have the red dot mounted with a HHA optimizer on the bow and it is shooting great again
one issue was the wisker biscuit rest was off center, so I had a hard time lining it up by eye, but now it is close to center shot
now I can dial to 25 out to 40 , used a blank tape and backed it off and marked the tape as I went.
shooting 21" accuspines with a 3 blade expandable, same as field points, should be a winner if the scope doesn't loosen up
may take some moldable epoxy on the rail to cement things up , have been successful with that on a few other crossbows
where rail fit up is not exact and needs shims to lock them down.
