Take it to a gunsmith. He will shim it for you.

Since it's the gun, I'd shim the sight instead of filing it. But I'd put a dab of glue on the shim once you know it's true. That way it will stay on the base if you remove the sight for any reason. Then a little heat will release it if need be.

There you go and now use your gunsmithing knowledge to take care of it and to do it the way that you feel is right. Wish you would have brought that up sooner instead of asking how to do something you had already knew how to do yourself.

Me personally I would not mill a flat on the action but file the base to fit. You actually scared the Hell out of me when you mentioned milling a flat. If you had done such a thing to my own I would have been extremely pissed off it would have decreased the resale value of the rifle at least 50% or possibly even more. Did you take an online gunsmithing course or did you actually attended one and for how long. If your instructor had actually taught you to do such a thing he should have been fired and someone qualified should be teaching him.

Yes a joke. I would modify the base. But to answer your question, yes a two-year resident program with the first year being almost completely machine shop. 

One of the instructors (Machine Shop) used to grumble about us gunsmithing students, all two of us. He would say "Damn gun cranks, mark everything with chalk and cut it with an ax".

Where's Chuck Blender when you need him?  He could give some good aesthetic advice on how to fix a crooked sight.

I've got an OT bolt action Stevens .22RF rifle I built up a "target" style stock using wood and bondo about 55 years ago when I was a young man in high school.
I wanted a target .22 rifle, but my part time job at $1.40 hr. didn't allow such a grand purchase. So I traded a tune up, and some repairs on a friend's car for the Stevens .22 rifle. I saw a story in Guns and Ammo about reworking a factory stock to target style by cutting and adding wood with dowels, and filler. So went to work cutting and adding a high comb, cheekpiece, wide flat forearm, and an exaggerated pistol grip. All done with wood, and some Bondo filler where needed. The grip was my finishing touch where I got the general shape in wood, then put a latex glove on, and after coating the grip with Bondo I shouldered the stock and grasped the pistol grip to make it fit exactly to my hand. Painted it all sating black after some sanding to smooth it out.
The barrel was pencil contour, so I got a piece of 3/4" black pipe and opened up the breech end until is slid over the barrel and butted to the receiver. Then put small spacers between barrel and sleeve at the crown, and used Acraglass poured in between the two until it was almost full. After setting up I removed the spacers and topped it off. Blued the outside, and mounted a 3x9 scope on the action.
It's a pretty accurate rifle, and more so than before adding the changes to stock and barrel. Still have it after all those years, but haven't fired it in decades. Poor gun got put in the back of the safe when real .22 target rifles took it's place. Was going to give it to one of my grandkids, but they deserve better guns!
