Just spoke to LimbSaver. My Wingmaster BDL's butt, without the OEM butt plate is curved. They do not sell a screw on that will work for a curved butt unless I buy a spacer, available at Brownells, shape that to make the butt flat/ straight and then, they might be able to help fit a screw-on, absorbing butt plate. They do not sell a bendable product to contour to the curved butt. They do not recommend sanding their butt plate to try to match the curve either.
Jeez-Louise !
What a PITA.
Getting closer to the reality of needing a slip-on !
