I may be going out on a bit of a limb here, but I wouldn't be at all surprised to hear more stories like this come along, and more and more people selling firearms at relativity good prices to people they know who are "Firearms Enthusiasts"
The reason I say this is, I personally know of at least five people in my life who at the height of the "Gun buying frenzy" felt compelled to go out and buy a gun (for various reasons) but, mostly out of fear that they soon may not be able to legally do so. Well, now things seem to be calming down, and many of those people that I know that did that are now re-thinking their choice and deciding maybe they don't want a gun after all. (their choice)... Long story short, I look to start seeing a bunch of these guns being sold on the cheap, and sometimes they forget to give the ammo to the purchaser of their gun, so they give the ammo to someone they know who shoots.
