Hi Folks,
Over the last year I have imported from the USA the following with no problems;
Trijicon ACOG TA01

http://www.opticsplanet.com/leupold-mar ... lized.html (mine is a standard version).
If you buy from a retailer they will have someone you could email, to see exactly what the situation is.
It has worked for me.
