Good day members

I need advice please. I will be purchasing a set of double rifle barrels and a reamer , .450 no 2 NE caliber next year. My brother in law from Wisconsin is visiting as well and I want him to bring these items with to South Africa. Can he bring it as additional luggage? Will it be a problem at customs? What is the correct procedures?

I really would appreciate your advice.

Regards

Gert
