The "extra" weight of the 16 ga. RBL is in the stock. The frame is small enough that the 29" barrels weigh less than 3 lbs. The replaceable pad system adds weight, but the stock is also pretty thick -- the straight grip on mine appears to be about the same thickness as the butt. I ordered mine with splinter and no pad system, and with a Galazan pad and 14-7/8" LOP it weighs 6-3/4 lbs. This is just what I like for pheasants using 1-1/8" loads. They bored some wood from the stock, but one easily could bore out more to get to around 6-1/2 lbs. I'm guessing Chief's gun had lots of wood bored out, and maybe has a shorter LOP and buttplate?
