chief: it has been done. i have seen fluid steel tubes sleeved to parker damascus breeches. when blued it all looks the same color with no hint of damascus pattern showing through. this gun is regularly used for skeet shooting and bird huntin, so it takes the pressure of field loads just fine...however, you are looking at a cost of probably $2000 by the time you have your new barrels fit to your receiver and forend...is it worth it?

keep it simple and keep it safe...
