This is my take on LR and WF guns. The only difference is in the selection of the barrels with thicker walls and weight of about 1 pound more than regular 32" barrels. I have measured my Wildfowl 2-3/4" chambered and the bore and chokes are no different than those on a Speciality Grade. The options of 3" chambers, reinforced rib were then applied if so ordered.
