M855CS

[Wildcat]

I was looking at some Federal 5.56 ammo and came across this.

What does the "CS" stand for?? I don't remember seeing it before. I normally just get M855.

As long as it says XM855, you're getting the same stuff. The suffix just indicates the packaging. In your case, the "cs" means 1000 loose rounds.
