I wanted to have an adjustable butt pad with a little more vertical than the one offered by Accuracy International. The one pictured is 3 D printed, If I get enough interest, I am going to make it out of Black Anodized Aluminum. Vertical adjustment is 1.5 inches. It does add 1.5 inches to your length of pull. Cost should be around $125,00. Please let me know what you think.
