Not to put words into Blue's mouth, but, IMHO, he's just pointing out that the particular bolt in that BCG is being advertised as "Mil-Spec" as indicated by the arrows he drew.

Well, you would think that. Because you’re a smart guy.
I zeroed the Geissele yesterday for a hunt tonight. I’m not sure if a $300 BCG with a non-mil spec bolt makes my horse higher nor shorter. Hopefully it doesn’t break.
