Taipan Veteran .22 moderator grub/set screw dimensions

Hi All,

I've got a missing grub screw from my shroud and while the user manual IDs this as part # 81, it does not give dimensions and thread.

Does anyone know off the bat what this is?

Little blue locktite coming next time.

I just removed mine from Vet Long .25

OD = 4mm
peak-to-peak = .5mm (but it's hard to see and measure and the only ones I find online are actually .7mm)
