    This thread is full of ad homonym attacks.

    Either the parts are good, or they are not good. That can be determined by inspection alone.

    For me - I will use NiB parts when I am sure the underlying components were machined specifically the right amount undersized for the coating application and to what I feel is the correct thickness.

    What about components machined " net to print" then coated with an EPMF? (Extreme Pressure Micro-Film). The thickness of the film is .000029" with a Rockwell C over 80.

    To be fair and honest, I did purchase a Spikes Nib BCG some time ago to see what the hype was all about. Doesn't mean I like the company. It works fine. It's extremely slick (I lubricate it as I would any BCG), and it cleans up easily.

    It's obvious that NiB is superior to phosphate. NiB clearly has a future in firearms. If somebody produces an entire upper receiver group including bolt and BCG machined to dimensions that allow a proper and thick NiB coating, they will have made a winner.

    Right now I'll continue to choose traditional products from quality manufacturers. When somebody does what I said above, using proven quality components as a base, I will go that route with NiB.

    While we can all agree that the AR platform is a wildly successful and proven design, I don't think anybody believes that it is the absolute pinnacle of firearms technology. There is room for improvement. We shouldn't collectively shit on every experimental coating / design JUST because it's different. If there's a reason to shit on it, believe me I'll jump in. It takes failure to gain success. So far, I've found no reason to call NiB a failure.

    It will have no corrosion protection so it is a no-go, unless done over a base of high phosphorous electroless nickel of about 0.0004 thick.

    Also I would want to see the coefficient of friction - if it is not better than nitrided steel, you could just nitride the carrier (I would not nitride the bolt).

    EPMF films are inert...they do not corrode (react)...

    CoF measured against steel(dry conditions) = .04


    (For Comparison)
    Chrome = .3
    TiN = .5
    Nickel Teflon = .2

    If you apply it to bare steel, the steel will rust. This is why ION Bond is best over a base layer of electroless nickel.

    We have some aerospace and heavy ordinance parts here where I work. They are made from several types of ferrous steel. All have EPMF on them and no rust or corrosion (reaction) at all. If oxygen can't get to the steel, it can not react (oxidize) with it.

    Send it to me, and I will have it 5% salt-spray tested and give an hour rating. If it is 100 or more hours, then it is interesting.

    I can't send you Uncle Sam's parts, my employer would boot me out the door. We manufactured some parts that were subject to ASTM B 117-97 Salt Spray Test. They looked great after 192 hours. I will get some info compiled and report back in the next few days.

    Were the parts a stainless or carbon steel?
