AR15 gas port relocation.

I have a new M&P 15, mid length barrel with a carbine gas system, I have never had a setup like this, I don't really like the carbine gas system on the mid length barrel, it doesn't seem as "smooth" as the mid length set up.

I am thinking about plugging the carbine gas port and drilling a gas port at the mid length position, and relocate the FSB. I have the equipment and skills to do all this work myself so it won't cost much.

anyone have any tips about this, my only concern is drilling the new gas port, it's a chrome bore. I wonder what type of bit to use for this to make the new hole as clean as possible. 118 or 135 degree drill bit?
