Short answer to the short question - No, it is not over.
You mentioned seeing "parts, accessories and ammunition that was almost impossible to come by 3 weeks ago is now readily available at several venders with declining prices..." I'm curious as to what those parts, accesories and ammunition items are, because it's still damn tough to find most things.
The only thing I've seen making a comeback is .22LR ammo, from certain manufacturers, and it sells out immediately.
