That is too bad. In the US firearms can only be shipped to licenced dealers.
Certain parts but not action can be send to persons in the US.
As an alien you are not allowed to buy firearms and certain related items in the US , there is a long list of those items.
Licenced dealers are not allowed to send gun parts to Canada without an export permit. The export permit is quite expensive. Each individual shipment requires some sort of authorization. Like complete action need a Canadian import permit since an action is considered a firearm both in Canada and the US,
The manufacturer has to submit the Canadian import permit and his export licence to the BATAF in Wasshington DC which will then issue an authorization.
Once you know how to go about it is is quite simple, but not every manufacture will bother with the extra paper work involved.
If you want to import an action form a maker, you get him to assign you a serial# for the action which you preregister with the Can. Firearms office in Miramachie NB even though this action is not made yet.
Then you apply for an import permit, you attach a copy of the registration, which you send to the action maker in the US.
He takes all this stuff and send it to Washington and gets authorization to ship to this action to you in Canada, providing he has an export annual licence. For you to receive it is no trouble since it is already registered.
Some individual may get you a new barrel and ships it to you. He would have to send his frame to H&R, since they don't sell barrels alone without them fitting it. The reason for that is CYA. liability.
Or you just buy another two Hanidi's in gauge and caliber you want. Never see too many on the second hand market.
