Joe,

I am pretty sure I have the same problem, I will try some silicon lube and see what happens. I have looked at their O-ring under 40X scope and I see some flaws. That is what the silicon will take care of. I will try that tonight.

BTW, if anyone has a leak on the retract cylinders, take a look behing the cylinder. there is couple of holes that you could use a snap ring plier to rotate and tighten it a bit. There is o ring at the interface so do not overtighten. Add some silicon grease and tighten till there is no leak.

Regards,
Mike
