I need to know what drill bit to buy for the right side of my ak builder flat. Does anyone know what size bit to buy for the right side fire control hole that is not drilled all the way?

Also what size bit to help line up lower rails ?

5mm for the right side FCG holes. http://www.ak-builder.com/index.php?dis ... t_id=30055

You should buy a reamer as well for precision

I wouldn't even bother with the 5mm drill bit if I were you.

Most people don't realize this, but a drill bit doesn't drill a truly round hole, it can't.
To get it perfecly round, you either ream, or bore.

I like to drill the holes to 5/32 and then ream to 5mm.
