I haven't seen but a couple available for sale, and they were HIGH as HELL on Gunbroker!!
Yes, most things I have looked at on Gunbroker are price gouged over MSRP by a good margin. I remember the original 'assault rifle ban' where two years later the Denny's overnight cook or Walmart cashier (and similar) had a $2K~$3K AK-47 clone they wanted to sell and could only get $600~$700 for it.
Like the stock market, buying high and selling low is a good way to lose a lot of money. Firearm panic buying is very similar to things like the recent Gamestop - Wallstreet bets type of action if you ask me. YMMV
