Getting a SCMIII in a trade, but it has reg creep. Guy told me AKA would fix it free, but I would rather just fix it myself if it is something as simple as an oring.
Should be as simple as replacing just o-rings. It is possible though that it doesn't have scm III internals though, would need to see a picture to know though.
The face is different for the brass piece. I have a SCM tool and probably the orings if you need. No reason that it shouldn't it's just possible if its an older SCM.
