I doubt it. It will be the same as receiving mail from any country outside the uk. What pertains to us us that within the uk, guns in the mail is against the vcr act. Countries outside of the uk are not restricted by this act, so can poat to us without restriction.
What WOULD be bad is a taxing system like when ordering from USA. We may have to pay extra. I thnk it will still be better prices though, so it all comes down to exchange rate
