You can find them used on gunbroker, auctionarms, gunsamerica, pawn shops, guns shows, etc. They are also supposedly available new at some distributors as of now, so you have to go to some dealers and have them call all their distributors - different retailers use different distributors; some the same - there's overlap. But it may take some legwork. In 3-6 months, they should be in a lot of stores & thus easy to find.
