I recently purchased an X5 second hand that came with a an RM06. It had a similar problem but the windage adjustment was messed up and wasn't moving the dot. First thing I did was check for its authenticity and there are some good videos out there that help you with that. Afterwards, I decided to shoot Trijicon an email and last week, I sent the optic out to be repaired. It was authentic and they are working it right now free of charge as it was covered under the warranty. I recommend you do the same with yours so as not to void the warranty or anything. I only paid for shipping (which requires that you get insurance and tracking info for) and I am waiting for it to come back.
I hope this helps.
