I have used Hawke medium rings on my Scorpyds and now on my TP Siege. These rings work well for me with zero problems. You will have to try them to see if they fit you for correct height.

 

I was sent Hawke Rings with my TenPoint Package. I found them to be unsatisfactory. I dislike that they use a bolt as the foot for the picatinny rail..(round peg in a square hole) Also thought that the caps were thin.
Not a lot of recoil with crossbows, they are probably just fine. But I opted to go with Warne Maxima 30mm Medium Height. Much much better in my opinion.
I always completely disassemble new rings and clean everything with alcohol. Then torque everything with a Wheeler Inch Pound Torque driver.

 

I totally agree with you....Bought a set of Vortex Pro 30mm medium height....PERFECT !!!
