Yes it should be , you will always pay the VAT in the country of origin unless you are a UK VAT registered business then its zeroed at source .
Edit , post Brexit you wont be charged VAT at source on European purchases BUT there will be import duty , around 8% then VAT on top of everything , payable to HMRC , VAT registered businesses will claim the VAT back but still have to charge VAT on the items when they are sold, expect all guns and related products from the EU to go up by at least 8% , stuff from the US will remain the same as today.
