There are much cheaper, neater, and more efficient ways to raise a comb than to spend hundreds of dollars to make a gun worth hundreds of dollars less by installing an adjustable comb. Several of my guns have cheek pads, butt things, you name it, all removable, all cheap. None of them make a permanent change to the gun. I admit that I have one ugly competition gun that has an adjustable butt and comb, but I also have the original stock in case I want to sell the gun in its original configuration.
