BCG, chrome vs. nickel boron vs. manganese phosphate?

Love the NiB. Reasonable price and great performance. No experience with the other two.

Im partial to chrome BCGs. I have a NiB as well in one of my rifles but I don't have enough rounds through it yet to be completely sold on it. Lots of "claimed" coating failures with NiB that I haven't really heard about with chrome carriers. Phosphate carriers are still running strong too. Don't get too caught up in the latest and greatest.

I liked NiB. Then I tried nitride. I now use nitride and my NiB and phosphate BCGs are in the spare parts bin.

Phosphate carriers are Chrome lined inside the bolt housing.

Another vote for nitride bcg's, they're all I use now. My fav is the AIM v2.

This thread would greatly benefit from a poll.
That being said, I once owned a chromed BCG which I liked but didn't own it long enough to realize it's durability, or lack of, to have a firm decision. All of mine are manganese phosphate. |

I'm probably going with Toolcraft. Now it's a question of which Toolcraft and from who.

And while I am sure the Toolcraft bcg's are good, I seem to recall in the Henderson Defense thread he stated Colt and Daniel Defense bcg's were giving him the most service life.

Nib works well for me. The bolt is smooth functioning and cleaning is very easy.

My 50+ Year old Colt/Armalite Hard Chromed bolt carrier with an insane amount of rounds on it, that still looks brand new say's Hard Chrome is best.

I have BCGs in all of them. I prefer, in order from favorite to least, NiB, chromed, Nitride, phosphate.
I have never had a problem with any of them but find the NiB and chromed clean up so much easier and are visually easier to see if they are clean than the black nitride and phosphated BCG. The phosphated are harder to clean and seem to need more lube to operate as smoothly as the others. All will work just fine though. |

The phosphated are harder to clean and seem to need more lube to operate as smoothly as the others. All will work just fine though. I prefer NiB for extreme operating environment where dirt, water, mud, sand might get into the action or where lube might not be present or available. NiB has the highest lubricity (slipperiness) and cleans up easiest. I chose WMD guns version. Just wipes clean. My nitride BCG is QPQ SN treated from Toolcraft. It cleans as easily as the NiB but not quite as slippery. It is super hard and corrision resistant. It will probably have a longer service life, but might not run as reliably in dirt, sand, mud and such. My phosphate BCG came from Spikes Tactical. Fully mil spec. It needs to be run wet, but should last a long time if kept properly lubed. It is harder to keep clean and needs some scraping sometimes, especially the bolt tail. I am now reserving it for a backup role. |

Hard Chrome is awfully hard to beat.

As to carbon build up, my NiB made by WMD just wipes off. Carbon is not sticking. My Toolcraft nitride BCG is almost as good, but takes a little more work on the tail. I use an Otis BONE for this. The hardened surface will not be damaged by a scraping tool. Phosphate - a lot of scraping |

Prefer Nickle Teflon, then Ion Bond. So none on your list. Have melonite stainless and they are OK. Have milspec phosphate and chrome and also OK. Making Ni/Bor or Ni/PTFE perfectly clean requires Flitz and bow grease and makes them shine. I find that mildly annoying. Ion Bond wears less than melonite... almost not at all. It's easier to hide insignificant carbon. It's less garish.
Had chrome in the past. Little wear, does not require Flitz, but not as easy to clean as others. Still easier than phosphate. Still buy 50% phosphate Toolcraft due to cost. Works perfectly fine. While it requires more oil, it holds oil better. |

Chrome is the best. Thousands of rounds and it still looks new. So easy to clean, just wipe it right off.

I get it, gas keys can come loose and leak. None the less the emphasis is on the bolt being the major wear item. But ok you have a made a valid point I suppose. (I did not go back and look to see if he consistently specified bolts only, giving you the benefit of the doubt) |

Christ's sake.....if I'd have had to poll every decision on every component I'd still be on my first AR build!
Buy it, build it, shoot it. You'll learn more as you go. |
