5.56 AP/Tracer, Endangered species?

[Meta]

I acquired a bunch of ammo from a friend getting out of shooting and among the huge assortment of stuff is what is marked as 5.56 Armor Piercing/Tracer. It appears as either a tip painted a combination of black and red (black like normal AP with a tip of red) or painted red like normal tracer with a black painted tip. Does such a creature exist and what's this stuff worth?!?

I dunno if there is any truth to this but, from a archived thread over on AR15.com it was said

"The red/black is a home or civilian attempt at a Soviet API type bullet marking, except the Soviet Bloc API in all calibers is black/red tipped.. Hope this helps clear it up somewhat."


outside of that post there is nothing I could find on black/red or red/black tips ammo

maybe pull one and section it?

I am pretty sure there is no US or western AP-T 5.56mm

And, those look hand painted...

The cases are Chinese, if that helps sort this out.

Found this reference that mentions them:

As posted above, they are PRC rounds, and we never imported any other 5.56 loads from China than ball. And yes, that is not factory paint work. You have a handful of gunshow specials.

Roger that, as suspected. Still, best to confirm. Thanks guys.
