    If you're going to run nickel then buy a Sionics NP3 BCG. Most of my BCGs are BCM with a few Colt but I have a couple Sionics and they are good to go. I tried some nickel boron but the finish wears off easily even with the best mfg. I fired thousands of rounds to come to this conclusion. There is guys here far more experienced than I which I'm sure will agree with my findings.

    BCM phosphate and Fire Clean. Why use anything else?

    I agree wholeheartedly. NiB does offer some improvement over standard phosphate but in my experience the gains are marginal at best. Honestly FireClean on Phosphate will do everything NiB will. For the price and Value the NP3 is a better option. Now if $ doesn't matter look at Cryptic Coatings CVD/PVD treatments, have personally fired over 10K+ documented rounds I have found that they actually deliver what they advertise.

    I think that the people who say their nickel boron BCGs are slick enough to run without lube are making a big mistake because the thought of metal grinding on other metal at fast speeds without lubrication seems like a good way to wear out your parts. While the nickel boron is slick and it runs smooth when the line is starting to wear off, I would never run my rifle completely lube free.

    Bottom line is NiB won't make a crappy BCG better, and poorly done NiB won't make a good BCG better. It's not a simple NiB vs. phosphate question, as it depends more on the BCG in question. A good BCG with a good NiB treatment can have some advantages, just make sure that's what you're getting. Otherwise I'd take a quality phosphate BCG over a bottom barrel NiB setup any day.

    And I agree NP3 is even better than NiB, but again make sure it's from a known quality manufacturer.

    What is everyone's thoughts on the AAC BCG? I have a 9" upper waiting to be approved. Just wondering if I should sell it and buy a BCM.

    I would say the random shortened life negates any other advantage. It seems nib is too brittle and gets cracks that propagate into the substrate. I only tested one failed bolt, others have had similar failures, and the base bolt was made right according to description.

    NP3 > NiB

    Otherwise just use a good old fashioned phosphate and your lube of choice.

    My Fail Zero BCG did the same thing as shown in the video. I talked to Fail Zero at the time and they said it was normal & the carbon would break free after firing first round. I didn't like the that and started lubing it. I haven't had problems since then, but only have about 2000 rds fired using it.

    My primary rifle now uses a regular BCM BCG.

    I'd say it's a concern that the manufacturers of NiB products are encouraging people not to use proper lubrication, if that is in fact what they are doing.
