You flood the market with enough than it can happen. Look at the AR-15 market. You can build one for under 500 bucks. AR-15 market is in the toilet.
I don't view that as being in the toilet. More and more people are buying their first "black" rifle. It's more attainable for your average joe. Which is much better for all of us in then political spectrum. Not to mention on a defense from tyranny stand point. Which is coming soon... But I digress
