As fa as I low from having had several original Bansner stocks,solid fiberglass pillars were molded into the stock,as opposed to adding them afterwards,as we do with some other designs. But each stock had to be bedded to the rifle.
Seems that has been replaced by the aluminum bedding blocks, probably to facilitate easier manufacturing on a mass basis as opposed to the older design which required individual bedding of each stock,which would be more expensive and time consuming....one of those little things we do for ourselves or paid Bansners to do for us...a "custom" touch. Not something we usually get in a production rifle.
