For a couple of years when I lived in Laramie the only "stocking" gun dealers (i.e. places where you could walk in, buy a gun and walk out) were the West Laramie Fly Store and Wal Mart. A few years later I think a shop opened up in the downtown area off of 2nd street but I don't know if that's even still there. There were plenty of FFLs would order or receive guns purchased through GB, etc, but those were the only two places that stocked guns.

Still, IIRC Wally World didn't even START selling "Tactical" guns until a few years ago when they became trendy (I'm pretty the first time I saw an AR in a WM store was some time around 2007.) So I don't think this is going to be much of a loss to the shooting community. My guess is that WM will continue to sell guns and ammo particularly in places like Wyoming where there might not be any actual "gun dealers" in a given town.
