I wonder how many remember 2008.
This has happened before and it will happen again; the same MO will be followed.
In 2008 it was about 8 months before everything really returned to "normal". Based on that, I would expect normal availability of most stuff in free states to return sometime around the fall timeframe. AR stuff is already pretty much back. Ammo and components was the last to return in 2009 and I don't see any reason to expect something different this time.
What we have is a market bubble driven by emotion and unrealistic expectations. What happens to all bubbles? They pop.
End of 2009 to 2012 saw the cheapest AR prices I ever recall seeing. Everyone bought them for up to $3000 in the election rush, then inevitably the demand fell off, and the market and prices bottomed. That isn't good for the industry either. As someone mentioned, sure they are loving it now with the rush, but they can't increase capital investment in greater production capacity, because they will be left holding the bag when the demand inevitably pops. They have to maintain production at a relatively low level to at least try to avoid "feast or famine" roller coaster.
Bottom line, we are our own worst enemy.
