There are so many AR's out there, not to mention uppers, lowers, and barrels that haven't been assembled. - any real price hike is due to pure panic.
I remember the day when I was told we would never see $500 AK's again. That proved to be false. At some point all these AR and AK speculators would probably want to cash in on their investments, or at least try to recoup some of their spent money.
While I am willing to pay a slight premium on some handguns that we might not see in production any longer, I'm not buying any AR's or AK's.
