Scope mounts is not a common tap / drill size.

You would be better off to take it to a gun-shop and have a professional do it for you.

It can be done however NEF says not to, you will need a bottom tap, or first drill the holes and start the threads with the tap in all the holes, then grind off the pointy part of the tap leaving only a small taper to the threads and finish the holes to the bottom, depth control is important with that thin chamber, so get a drill stop on the drill before you start drilling.  Take some super glue and glue on the scope rail getting it strait and on top, then take a drill that just fits in the scope base holes and drill a very small start in each hole, use this to locate the tap size drill holes, the scope base will pop off the super glue with a sharp tap with anything hard.  The tap is a number 6-48 national special.  Nef does drill and tap their slug barrels.  Good luck, and glue will work for only one shot.  Larry

Basics: shotguns work under 20K CUP pressure and don't have to be all that thick. Drilling "thin" metal is alot more risky. Your call.

b). If the "mount" is not going to be used on a real light gun that kicks like two mules, AND you have a real great man with a torch, you might get away with brass/ brazing. Of course the mount will have to be steel too, not aluminum. They are available, just cost more. And the "pro" touch is "nickel silver' soldering. That should hold on a magnum and most guys with a torch can handle the job. Either way, you may need a refinish, "blue?", if the man is not an artist with the tools. Fair amount of work and cost for an inexpensive gun. luck.

I had a 20 ga. drilled for scope by my local smith, but I think there is more meat in that barrel than the 12 ga. ?
