I checked the barrels on my Wild Fowl military. Muzzle to choke beginning rt.bbl=2.15" lt.bbl=2.25". Max choke both bbls.=.6895" Bore diam. both bbls=.729". These barrels do not appear to have been messed with in any way. I also have an almost new Eagle Wild Fowl that I will check when I get some spare time.
