I have a H & R 12 gauge I want cut down to a legal 18.5". i also want to have a XS Big Dot Tritium sight (or similar) installed. I have been toying with the idea of having a 3.0" section of Picatinny rail silver soldered or epoxied to the underside of the barrel to mount a light. This is a home defense gun for my 76 father to keep at his secluded lake house. After I get the barrel shortened, I am going to send it off to be Magna-Ported. Does anyone have a gunsmith (TFL guy) who they would recommend for this shotgun work? I would rather UPS the barrel out, than drive around to see my local idiots. Concerning the rail idea, someone is going to have to match the radius of the barrel. Obviously, this will take a competant machinest, this is partly the reason I want to send it out. Thanks.
