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 ?

Re: What size drill bit for right side ak74 sidefolder flat

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.
