Handy for adjusting your stock - MDT Vertical Buttpad Adjustment Base

I actually flip it upside down so I can move the buttpad down further and get a more upright shooting position for my head while placing the buttpad on my chest. Most people use it to get the buttpad up higher. It goes up 2 inches and down .75 inches (unless you flip it upside down like me). Rubber pad has nice texture, grip and curve to it, comfortable to shoulder.
