About AU: communication was lightning-fast and the case was shipped very quickly. It was wrapped in very tear-resistant plastic. There was crush damage to the case, but the ammo was fine. Other than the required ORM-D sticker, there were no markings to give away the contents.
Now the ammunition: it comes in green-and-white "Magtech First Defense Tactical" 50 round boxes. Magtech is part of CBC. I find the 50 round boxes convenient when it comes time to load mags. Brass is shiny, the primer is lacquer-coated, and the brass is cleanly crimped into the bullet cannelure. The headstamp is "5.56 17 CBC" (fresh! lol) I don't have a chronograph, I only shot at 50 yards, and my skills and carbine (a 16" 1/7 twist Colt pencil barrel) aren't capable of testing ammunition to its utmostl, but the bullets go where they should if I do my part.
This is good quality ammunition that is at least suitable for plinking/training and is very competitively priced by AU.
