obviously someone buys the stuff or they would have been long gone by now?
Or perhaps not since they're closing up gun departments.
Honestly, if they're not moving product I don't have any issue with them closing up that part of the business. To a large degree this isn't really a "gun issue", is boils down to (1) online shopping and (2) a disposable culture.
As to online shopping, it's getting hard for people to deal in things in person anymore. The modern consumer for the most part seems to prefer to shop from their own home and wait for things to arrive. By cutting out a showfloor, salesmen, and a few middlemen, you can get a lower price and low price, much more than service, is what people seem to want (and I can't blame them - I tend to be the same way).
The second thing - regarding the gunsmithing business, would be the disposable culture. People don't look at fixing things when they break anymore. If something breaks, you don't fix it - you throw it away and buy a new one. At first it seemed like people were just not even thinking of repairing things, but lately I've seen instances of videos where people did fairly good repairs (and this is isn't just on guns) and the immediate response of many was that they were crazy because if the item malfunctioned they're now liable.
Its not necessarily a viewpoint I agree with, but it is interesting that many people don't want to take on repairing an item because they don't want the liability it causes if it fails. I think they viewpoint tends to even fall to letting someone else fix things. It's just one more message in the back of the mind that when something breaks, you throw it away and get a new one. As such its hard to keep any repair business open now - be it for appliances, guns, electronics, or anything else.
