[ARCHIVED THREAD] - Aero M5 Build Question

Posted: 12/19/2015 2:23:16 PM EDT

What's the size for the set screw that holds in the rear takedown detent and spring? I emailed Aero, and haven't heard anything back. (The screw didn't come with my Aero LPK, either.)

Thanks in advance!

4-40, just like AR's.
