It doesn't matter whether it is booze, 32oz. high sugar soft drinks, or AR-15's. When the government tells people that they don't need it, everybody has to have it and they find a way to obtain it. Prices go up with demand. Once demand is satisfied, prices drop, sometimes precipitously. Because of that, boutique AR's remain expensive, mass manufactured ones not so much so.
S&W had two or three SKU's when I bought my first AR from them. Now they have dozens. You can pretty much buy one in any configuration you want with almost any barrel twist at prices you can afford. This would not be the case if they couldn't keep up with demand for those first three configurations. The downside is that the perceived value of the ones we own has gone down.
