.300blk marked would presumably give the user "bigger balls" and can offer more "knockdown power" at the range shooting paper then the one marked standard.Since a .300 Blackout uses the same BCG as a 5.56/.223, why would they list it as a .300 Blackout BCG? I'm also curious about Radical Firearms' general quality. Their barrel prices are ridiculously low. Anybody know anything about them?
It is still an external coating that will eventually wear to the base material. It relies on 'high spots' to reduce friction and has absolutely no 'self lubing' properties. Once those high spots wear off, friction increases and you basically have a nickle coating. NiB also has the same corrosion resistance as common electro nickle/chrome plating and will not stand up to salts very long.Says here the flaking and debonding from the parent surface is typically because some coaters were being cheap- and/or dumb-asses.

For what it's worth, I bought a 1st-gen Spike's Tactical NiB BCG and still don't have any issues with it.
But you know them internetz stories... beats firsthand experience every time. :lol:
