I'd say that guns have gone up in price, and maybe not just because of inflation.
However, look at all the companies which are making ARs or AR parts and accessories. In 1992, I don't remember any rail systems, good lighting systems, different barrels, brakes, uppers, lowers, stocks, etc. as there are now. I also don't remember as many AR owners as there are now.
Ultimately, when your parents tell you that you can't have something you want, more often than not, you want it more. If anything, the AWB created an artificial demand for a product previously in ready supply. Were less crimes committed with the AWB? No. Did a truckload of people from gun dealers, gun manufacturers, and parts manufacturers make money? Yep. Did you buy your AR (and hold on to it) after the ban? Probably.
