    Ive ran a few thousand rounds through a basic R guns bolt carrier with zero issues, and just started running one of their lowers and lpk, a couple hundred rounds worth so far, zero issues.

    Could you do that to a standard carrier or would the nitride process damage/change the tempering of the steel. Can NiB be applied to nitrided treated steel? Or would that be over kill?

    You can nitride a standard carrier without doing harm to the steel, but I am not sure what it would do to the chrome plated bore.

    I can't think of a reason to NiB over nitride.

    I have been wondering about that for awhile, would it mess with the chrome.

    In the BCG which is better NiB or the nitride?

    Why would you not want to nitride treat the bolt? and what about the cam pin?

    PS. I hope you don't mind me picking your brain about this stuff.

    DONT do it to a chrome bore... i had a bunch of stuff done for testing, BCG, barrels and more... the chrome in a barrel is so thin, it burns it off and the barrel is now a 4moa gun...
    i did 5 carrier's and they were great!

    Nitride is black, which some people require. NiB has a lot more lubricity, which I like, and I will take that over black of less lubricity.

    Nitride has a lot of corrosion resistance. Thin NiB, not done over a base layer of high phosphorous electroless nickel, does not. Most of the NiB you see out there is thinner than desired so that it does not mess up existing part tolerance as much.

    Nitride does not add thickness to parts, so it is easier to do to a carrier - but you would still need to not chrome the bore, and still need to ensure that the bore ends up in spec.

    ION Bond or other PVD or DLC is thin, but does not have much corrosion protection unless done over 10-12% phosphorus nickel, but if you do that, it is no longer thin.

    Bolts are more at risk of failure if nitrided.

    Cam pins are designed around a dry-film lube of a certain thickness - so if you nitrided an existing cam pin, it would be too small diameter if you did not apply the film back over it. Also it may not have as much lubricity.

    I believe in NiB (it is not snake oil), but only if:

    1. The NiB is thicker than most are doing it.
    2. The NiB is over a base layer of 10-12% phosphorous EN to add corrosion resistance, and that also needs to be thicker than how most are doing it.
    3. The parts it goes over were specifically machined smaller by the same amount as the thickness the two layers will add.

    It gets so costly to do it right, and since it is not being sold to the govt who gauges things, I think more likely than not the NiB parts out there fail all three of my requirements. I am speaking in general terms, and not about Spike's or R'Guns stuff - which I have no specific knowledge of.

    And how is that bolt carrier working out? Do you have any pics of it showing some where and tear and chrome chamber/gas tube area?

    On the lighter side of things, your "bolt" looks looks more like a bolt carrier. Did it get a make over as well? (j/k)

    i had 5 done... havent had that many rounds in it yet to say

    nitrideing will remove the "flash chrome" ..
