This cheekpeice/shell holder is a great upgrade for the Blackhawk Stock. I got it to help reduce the cheek slap normally associated with the Blackhawk recoil reducing stock. You have to make a decision of the high or low riser before you do the final install. Once its installed its almost impossible to remove it without damaging the stock/riser.
