What is this 5.56 round?
 
1 Attachment(s)
Well, I was skimming through some ammo that my dad had given me a couple years ago. Not sure where he got all of it. One round that stuck out is a yellow tip 5.56. Headstamp is LC 87 with NATO stamp above it. I have not been able to find any definite info on this. Can someone please identify this round? ,

LC 87 - Lake City Arsenal 1987

Found this from AR15 forum:

Which headstamp do they look like? Left or Right? Left is the old school headstamp that is typically used on BLANKS the only ammo from LC with that headstamp will be BLANKS and XM-193
There is not XM-855 product anymore it is XM-556 which is seconds (That is to us at LC) IF the ammo has the headstamp on the RIGHT then it COULD be M-855 or M-193/XM-193, this product is manufactured on the SCAMP equipment and is considered "COMBAT" ammo, and has the NATO markings. BUT no 855 leaves that plant without the Green Tip, no Tracer leaves that plant without the Orange Tip... Any unidentified ammo is destroyed. Called Strangers and placed in stranger boxes in the buildings and sent to be burned. (unknown lot numbers etc.)

Yes, but yellow tip?

Looking at the sites, I doubt the bullet was manufactured in Hungary.

Some sites for checking on the codes:

If the round does not contain a duplex round, the yellow top could be a "Starburst" round, which can be used for spotting or a light incendiary. This round contained flecks of titanium which ignited and were thrown up to 10' upon striking a target. These rounds throw a bright shower of sparks in darkness and should be easy to identify.

Either way,these are expensive rounds.

Hmmmm. Thanks for the research. I only have one and since it could be a starburst round I'm definitely not dissembling it. Very interesting
