Maybe you might try one of my Front rest tops on about any heavy base. For a front bag I prefer a Protector bag with slippery cloth. I use a tall rabbit ear bag on the rear.
Shown is a shot of our early model rest top on a Bald Eagle base. Our new models have a longer joystick. It is a coaxial rest and offers 22" of vertical and horizontal movement.
