I have a 308 I shoot in competition but have to use a leather cheek riser which rises it up almost an inch. Since I am using a 30mm scope with a 50mm objective the rings are medium height. I would like to install a comb riser kit from brownells but I’m worried about cutting into the stock. Are the HS stocks hollow or have a soft core? If someone knows or has done this in the past any insight would be appreciated. I really don't want to ruin a good stock.
