[ARCHIVED THREAD] - Mag release drill size

Posted: 1/17/2021 10:57:56 PM EDT

So Ok time to ask the hive once again
I am working on a 80% and after milling it I found that the mag release hole had not been drilled, I have on old plastic jig that has the opening for the drill but I have no idea what size drill bit I should use. So as always I really appreciate the help.

I guess I should clarify I know the mag release is a stepped hole. What I was asking is the size drill needed for the shaft on the mag release.

Low res LR-308 print, but it looks like 0.20". I'll look for a ar15 print.

Edit: add
Here's a AR15 print and it appears to be 0.20" +- 0.003"

Yep, sorry. I need a higher resolution print. The 4+ in the 0.20 4+.003 almost looked Japanese.
