Archived [ARCHIVED THREAD] - Sight apertures?
Posted: 8/17/2003 4:01:17 AM EDT
I have a Bushmaster A1 rear sight and I was wondering what the sight aperture measurement was for it. I want to replace it with one of those competition sights but I don't know how a .036" aperture compares with what I already have.
