The Luth-AR is just the upgrade you need as it offers near unlimited adjustability. The cheek rest has one inch of height adjustments and the length of pull can add an additional 1-1/16 inch to be custom fit to your arm length. The rubber pad can also be raised or lowered depending on your preference and shooting position. It is compatible with Mil-Spec or commercial 6-position tubes and is made from glass-filled nylon that retains strength while reducing weight. The MBA-3 is also compatible with rifles if you get the correct buffer.
