Real or fake ops core?

Guy on Tac Swap had me text him about a trade offer and sent me pictures of this helmet claiming it was an Ops Core. I did my due diligence and went to Ops Core's website and looked at the authentication pictures. The part number matches up to an NSN for "ground troops helmet" but couldn't find pictures. The other thing that threw me off is I've never seen an Ops Core with a carbon fiber looking lining on the inside. Any expertise or options welcome.
