I recently was given a Landor Arms AR12 12-gauge semiautomatic shotgun. It's one of those Turkish made guns that has kind of an AR15 look to it, It has a 2 round detachable box magazine and a couple of additional 5 round magazines. The gun is new and has never been fired. It is still in the box with all of the papers including the choke tubes and wrench, instructions and a cable lock. It is a gas operated shotgun which I believe is chambered for 2 3/4 or 3" shells. I received the gun to look over to see if I wanted to buy it. My issue is I don't know much about these guns as far as the quality and functionality. I also don't know what the going price is for one of these either. Does anyone know the going price of one new still in the box? Also it it a decent gun?
