So I called FNH. I asked where these rifles come from and if they come with a warranty. At first the lady said she didn't know anything about Factory Refurbs. She put me on hold and asked somebody else who said they knew nothing about it either. Then I told her that the seller mentioned FNs "used firearm program." She confirmed they did have a used firearm program but couldn't say what was done to refurb them, where they got the rifles or if they came with warranty. After putting me on hold again and consulting with someone else she came back and said the person she was taliking to asked if I could send them links to some of these refurb listings on GB. I said sure. Even though this gal didn't have much info to offer, she was very nice during the conversation.
Looking closely at the pics on Gunbroker I see a little handling wear and some black marks where it looks like a vertical grip was mounted.
