Funny you ask, I haven't been on here in a bit and came to post an update! So here she goes.
Mossberg originally told me to contact Wolverine Supplies for repair. I reached out to them and provided them the story and photos to see what they would come back with. They reached out to Mossberg and apparently had to bring it to the higher ups. At the end, Mossberg agreed to replace the firearm with a new one. I am waiting for the replacement to arrive, which will immediately be made available for sale. Unfortunately for them too little too late, I am not a Mossberg promoter. That firearm will immediately be made available for sale.
As for Cabela's, someone else reached out to me by phone and apologized while throwing the previous person under the bus. He said that they would help look into a solution (this was before I heard back from Wolverine) but I haven't heard anything from them yet. It's been a week, who knows what will happen.
Now here is an interesting bit I learned. I contacted Visa for help to see if I had any recourse, which I didn't. Cabela's final sale policy forces you to deal with the manufacturer and since they offered (at minimum) to repair it, they are in the clear. If Mossberg had not adequately repaired the firearm I could then have filed a dispute.
So I learned two things from this experience:
1) Do not purchase a firearm from Cabela's
2) Do not purchase a Mossberg firearm
