The Obama administration has directly or indirectly caused several gun-control panics beginning in late 2008. With each successive panic the high-water price level for popular weapons has declined, because manufacturers ramped up production in response to price incentives and because panic is difficult to sustain. There is more market competition and improved manufacturing technology, so supply and quality have improved despite executive orders curbing imports. In 2015 you can buy a US-made budget AR-15 from a good manufacturer for around $600. Back in the early ’90s when these panics started a similar gun would have cost $2k+ in more-expensive dollars.
