Hello All-
I just got back from my local Cabela's with my brand new 5946 in hand. They had three, all in the gun library. One was labeled "New Old Stock", which was a Springfield, MA gun that I bought. One was labeled "New", which was a Houlton, MA gun. The last one was used and definitely from a different batch as the serial number was not on the right hand side. I did not look at the used one so cannot comment on manufacture. The prices were $599, $599 and $449 respectively. Both of the guns labeled new had 2014 dated night sights, 3 magazines, fired casing, all paperwork and matching serialized box. The fired casing for mine was dated 2/25/15.
No pic as it is identical to the OP's. I thought the days of walking into a store and buying a new third gen were long gone! Would love to know the story behind these.
