A young girl's elated reaction to being gifted a shotgun by her parents has caused a mixed reaction online after being shared by the gun manufacturer.

The girl has only been identified as Presley in the video shared by Italian company Beretta.

"She opens the Beretta box. Her reaction will make you cry," Beretta wrote on January 28.

"Making memories starts the moment you open your first 686. A touching video sent by Presley's parents, shows the emotional moment when she realizes she finally has her very own 686 Silver Pigeon."

In the video, Presley fails to contain her excitement as she opens a cardboard box to reveal a dark blue plastic gun case.

"Oh, my goodness. This is crazy," Presley says before screaming with joy.

Her brother encourages her to flip the case over so that the unveiling of her new gun can be done for the camera.

"Oh. I can't breathe," Presley says as she unlocks the box.

She then grins for the camera and starts to cry.

"Thank you," she says.

"You're welcome," her father responds.

She then cries and laughs as she pulls the disassembled gun out of the packaging, inspecting each piece.

A Beretta 686 Silver Pigeon costs approximately $3063.

While Presley and her father are clearly overjoyed, the reaction to Beretta's Facebook video - which has been viewed more than 7.9 million times - has been polarising.

"That's America. A place where you cannot buy alcohol or cigarettes if you're not 21 years old but you can easily have your personal gun," Italian Alessandro Alliata wrote.

"A world where people have such an emotional reaction to a device which only purpose is to kill, is sick in my opinion. The message this sends is so wrong," Pascal Gerlach added.

"This is highly disturbing. Did you realise that children like this one and toddlers have killed more innocent Americans than the Syrian refugees have in the last 10 years?" Kellen Lignier said.

"If this video showed a young Muslim girl being presented with a gift of a firearm you can imagine the collective fury of rednecks," Richard Wilson commented.

However, some social media users applauded Presley's parents.

"Oh I so enjoy reading comments from anti-gun people who know nothing of the sport or the level of skill and personal discipline that young lady had to show before her parents bought her a tool that will last her a lifetime. Who is to say, after all, that with dedication and practice Presley might not someday follow in the footsteps of another woman who started shooting clays at an early age," Frank Goth wrote.

"Sweet young lady with a wonderful family," Stacie Smith Starnes added.

"Now this is the stuff I love! Way to go, Dad! Sticking tight as a family and raising our children with values and life skills. America," Ryan McGrath said.
