It is becoming challenging to bring your shotguns from the US into Argentina. In years past, it was as simple as arriving at your destination airport in Argentina and filling out some forms with the RENAR department, and paying a small entry fee. Today it is far more time-consuming, more expensive, and requires much more planning on the part of the outfitter and an agent who will be your personal guarantor that signs a document as assurance that your firearm will leave the country with you at the end of your trip.
The Federal Police and government have also irrationally determined that a semi-automatic shotgun is more dangerous than an over/under or side by side. Due to their views of semi-automatic firearms, it is effectively impossible to bring even the most common shotgun like the Beretta 391 or the Benelli M1 into the country. Because of the known challenges and bureaucracy in place, Southern Outfitting will not facilitate and/or assist with the temporary importation of semi-automatic shotguns.
