Thread and length for AICS cheeck piece screws

[Andy T]

I am trying to figure out thread and length for regular (not "enhanced") screws used for the AICS cheeck piece.

If someone hasn't gotten back to you, I'll measure mine when I get home in a while. I have a short action 2.0 AICS.

If you are using the thumb hole stock M5 X 25mm, but if you are using the new AI pistol grip stock you can use M5 X 20mm
