I've been in touch with Primary machine who milled
two of my guns for 507Cs, Bruce was no help, told me
to contact Holosun to see what the sent with the sight???
That's what they used ??? (thanks)
Holosun was consumer friendly, confirmed 6-32 and
stated they send 2 lengths.
I still haven't had any luck matching them up, in the next month or so it's time to change the battery in a bottom
battery 507C, any updated info would be much appreciated!
