shipping personal aeg's

You have three options really:

Either-
Have someone in the US like friends or family post the rifles to you as a package like you would receive it if you ordered an AEG from any other country

You can, like was mentioned, have a trusted retailer send it here on your behalf and just go to the process as if it's an international order

Or, you can have someone that will be visiting you soon or if you'reback in the US yourself, bring your gear back yourself. You will need a hard case that fully locks and the airline needs to know what it is (send them an email is best).

The first options is probably the cheapest but also the greatest risk. It's a package after all from one individual to the next so there's really no guarantee it'll get here, The second option has the same problem. I've heard of people ordering from US or Asia and rifles getting stopped, checked and released or not stopped at all or stopped and destroyed, so it really is the luck of the draw.

The last option is probably your safest as it's own personal baggage but requires you to go back to the US and come back here, so that would be expensive.

Hope you get it sorted but unless someone here has afull proof plan I don't think there's any one sure way of doing this.
The obvious option is number one where the package is shipped to your Irish address by a friend or relative in the US but because there's no retailer marks on it or anything it may either look more suspicious or not at all and it'll go by unnoticed. Hard to say.
