Hi I have bought a few rifles in Uk as ronin said it’s straight forward to Northern Ireland RFD to RFD once that has reached Northern Ireland if the gun is going down south of Ireland the southern rfd applies for import licence . Based on make caliber , action type and serial number once granted it can be shipped down south can take up to 2 to 3 weeks to get import then the buyer of firearm can apply for new licence again can take from 3 to 12 weeks firearm is stored in rfd down south .
