I have an Impact with what seems to be a very common build - Saber Tactical rear bag rider, and Saber Tactical long arca/picatinny front rail. I use an Atlas bipod on the front with the legs at 45 degrees. I looked at a lot of bags and only found one rear bag that fit the height requirements to level my rifle: https://wiebad.com/mini-range-cube/
With the bag on its side, the height allows for level orientation or muzzle slightly up/down. On its end, the height is about an inch taller and allows for muzzle down further. Before this bag I was stacking foam pads with a couple different rear bags and never quite getting the right height. This greatly simplified things.
What rear bag are you using on your Impact w/bag rider?
