Can you shot this in any 223 and Thanks for all of the info.
M855 = US version of Belgian-designed SS109 semi-armour-piercing round. The green tip distinguishes it from the Vietnam-era M193 round. Canada uses the same (less green tip) as the C77.
TZZ on the other hand is, I think, Israeli, made in Tel Aviv. The cross-in-a-circle is the NATO standardization mark. '94' is almost certainly the date of manufacture.
