Heres my SCAR 16 gas port:
Port hole size is .055"/1.39mm and it comes rights out with a small slotted screw driver. This should be pretty easy to figure out the right size (if different) port with a brass set screw and some drill bits for SBRing…
Threads are same size as a Keihin motorcycle carb main jet. I thought that was kinda funny…
