Mossberg made some non-firing firearms designed to be used for demonstration in hunter education classes. I've used seven of these "guns" in teaching the course. In fairness, we didn't get a bolt action centerfire in the package (lever action centerfire, bolt action rimfire, pump, semi-auto & over/under shotguns were used). I don't know if the "demo" guns were made to a lower level of quality than the firing guns, but all of the seven that we used had real problem. Before I bought a Mossberg I would want to hold it first and be able to check it's functioning.
