I saw a BCG that was nitrided but had a chrome-lined chamber on the carrier. Is the chrome-lined chamber really necessary if the BCG is nitided?
I guess my real question is would a non-chrome-lined nitrided BCG perform the same as a chrome lined? |

Short answer is, all quality carriers are chrome lined Chrome lining and nitriding would seem to be a mute point. The chrome won't particularly gain anything at all from nitriding. Chrome lining is sufficient. The nitriding would make the exterior more corrosion resistant. I have not, generally, found this to be a problem though. |

Enterprises does not chrome line their Melonite carriers |

Chroming a nitride carrier would be redundant, since both chroming and nitride would serve the same purpose inside the bolt channel. If anything, I would think nitriding would have an advantage over chrome since it doesn't alter the dimensions of the host material and so the host material doesn't have to be dimensionally reduced to account for the expected thickness of the chroming.

IIRC, you cannot apply industrial hard chrome to melonite because melonite actually penetrates the base steel. |
| I am not sure about trying to apply chrome to melonite, my guess is it will not go well. When trying to melonite chrome you will gain nothing. The chrome does not have enough of the elements to take the melonite or nitriding process. You will treat the nonchromed steel, but the chrome will gain nothing. I am not sure you effect the chrome layer adherance or not. |

Quoted: Well, can you treat a chrome-lined BCG chamber with Melonite? Would the Meloniting process harm the chrome? I do not know if it harms the existing chrome. |

I'd like to know who offers a nitrided bolt carrier with a chromed bore.
I have a JP bolt carrier and while it is a very good carrier, carbon sticks to the inside more than ones with a chromed bore. The effect of this carbon and the need to clean it is arguable, I'm just stating that it is more difficult to get off the JP QPQ bolt carrier than a chrome lined one. The other surfaces wipe off just as easily, just the inside that is different. I'm not exactly sure how one would apply chrome to a nitrided part. I suppose it's possible but I'm not an expert in this field to know exactly what it does chemically. I would imagine the vice versa of nitriding a chromed part would have ill effects. I have accidentally nitrided a nickel boron hammer and it definitely messed with the coating in a negative way. |
