Possible ACOG leak?

[Duke of Lawnchair]

I have a compact ACOG that seems to be leaking a fluid.

The areas around the elevation and windage knobs are saturated with a light oily residue.

Is this common?

Thanks in advance,
Jim

I'm not sure that there is any fluid in an ACOG to leak out. Have you tried contacting Trijicon to ask them about the issue?
