I'll confine my inquiry to a Parker 12 gauge Grade PH size 1&1/2 frame 28 inch Parker Steel Barrels-- the barrel pre-struck weight is marked 4 (upper case number followed by a 5--could this mean that the 2 tubes, and the top and bottom ribs and the wedges and solder/flux should weight 4 lbs. and 5 oz. on a USPS digital scale. Next week I may just go visit my buddy Jeff at our Post Office and as him to weigh them for me--Naturally, I will just take the barrels in a case- NOT the assembled gun-- thanks RWTF
