I just received a 507k from a trade. I went to mount the optic on my PO9c Nocturne aaaaaaand its not long enough to actually thread into the holes  

Do I need longer screws? Does holosun or any third party make longer screws?

Larue sells screws.  I just bought a set for a MRO.

Call Holosun tell them what optic and what you are mounting it to and that you need the right screws . No the right screws weren’t in the box. Likely they will send them out free or for shipping .

Original box usually has three sets of screws different sizes different length.
Why the industry can’t standardize is beyond me but they don’t.

If you post a note in Hometown someone local may have spare screws also

If its a direct mount. It takes the M4 10.5mm screw.
