not to put a dampener on it.....but
You gotta watch gear coming in from the states. As long as there is a good full description on the item you should be ok.
If not, anything that may look like part of a firearm could be impounded by customs.
Check with the sender to see if there is a tracking number.
If customs do pull it, be prepared to pay duty, vat and additional shipping costs on your doorstep!
