Guys, I posted this over in the "Ammunition" section, but wanted to re-post here in case some of you don't go to that section often.
Century sent an email this morning, stating that they currently have tins of 5.45 ammo on sale. Normal price is $161, but they are currently selling it for $120 per tin. I also recall that Century has ridiculously cheap shipping if you spend a certain amount (I think it is $400?).
If nothing else, this would seem to indicate that the surpus 5.45 ammo is still plentiful, and unlikely to dry up in the near future.
ETA: This special is good until 4:00pm (EST) on November 30.
ETA #2: I called Century to order some of this. They told me that I had to have a FFL or C&R to order at this price, which they conveniently left out of the email. I am not a C&R or FFL holder, and never have been. Not sure why they would send an email to me that has prices I can't actually buy at.
