Here is what the owners manual says if i would have read it 
"NOTE: To comply with U.S. migratory bird laws, six shot models are shipped with a wooden dowel inserted in the magazine tube which limits magazine capacity to two (2) shells.
To remove the dowel, first remove the barrel. Point the shotgun downward and shake it back and forth lightly until the dowel protrudes from the takedown screw hole in the end of the magazine tube. A rubber “O” ring on the dowel prevents it from falling out accidentally. Grasp the dowel and pull it completely out.
To change back to a 2-shot magazine capacity insert the dowel through the center of the magazine spring so that it is positioned inside the coils of the spring."

I just started tinkering with it and was like hmmm why is that in there and took it out then realized what it did.
