IIRC, you can order them as factory SBR's, so no engraving would be required.
That's correct(the part about a factory SBR not requiring your info). I think you're also correct about Noveske offering factory SBRs, but I can't say from personal experience.
FWIW, my 6.8 is marked 5.56. Not a Noveske though.
