Im not sure what to say.The carrier keys on all my LMT BCG's show very light mill marks all over and are clearly not a cast part..I can say for a fact they are pretty darn hard too.I tried to dress down the staking on one of the keys to remove the raised sharp points(due to the fact it cut me) and it about dulled my file.Had to break out the wet stone.
If your concerned about it drop LMT an email and see what they say.
