I had the impression the original question refers to hard plastic (not springy foam) wedge shaped spacers that fit between the buttstock front and the rear of the action, used to alter the DAC and DAH of the stock fit. Beretta has them available for some models, but I do not know of "universal" models that are available. You could make your own by cutting plastic or wood sheets to an angle on a mitre box saw or something similar, but be careful of your fingers. Not sure how much you could actually raise the stock by doing this, and the "look" might not be real good, either, after all the fitting required. If I missed your point completely, chalk it up to being old.
