James, yes Sir, it is a 12 gauge Semi-Auto box magazine feed shotgun. Cheers and stay safe!

YES, this is a 12 gauge box magazine feed semi-auto shotgun that is style after AR-15. That is why it looks so much like AR-15 and not shotgun. Most US-made shotguns are usually tube feed, but box feed budget guns from Turkey are getting very popular. I hope this helps!

Hey no worries at the question when new to firearms there is alot to learn, and we all had to start from somewhere.
Yes this is an AR style, semiautomatic, shotgun, it has a detachable box magazine (as opposed to a tube fed fixed magazibe), and it has a 3" chamber that can safely cycle 3" shotgun shells and 2¾ shotgun shells.
It also includes 5 interchangeable chokes, which will change your spread/patterning depending on the type of ammo used.
If you need any more info on this or other firearms or features, don't hesitate to ask, there's usually someone here in the community more then willing to help.
