Trey,
nice pictures but not all that helpful. When you take the barrels off the gun there is a flat area in the chamber area of the barrels. This area is the barrel flats. Stamped on the flats and/or the barrels in front of the flats under the forend you will find all sorts of numbers, letters, and symbols stamped into the barrels, these numbers, letters, and symbols contain very important information about your gun. This is the information that you need to post here.
