    IonBond is DLC. FailZero is Nickel Boron. So yes, the OP is considering those coatings.

    Re: Chrome & Fail Zero:

    I've always noticed my Fail Zero coated LWRC Bolt Carrier's to feel much much, slicker after firing than a comparable YM Chrome Carrier I used in my DI carbine.

    No scientific data from me, here.

    But I have seen old Parked Bolt Carriers rust and pit. Not sure if a 15 year old chrome BC with tens of thousands of rounds would have had the same result.

    I was at Tripp Research hard chroming a bcg for my dad's ar and the bolt head and a few other pieces for my hk-91 clone build. I was lucky enough to witness the hard chroming process twice. its pretty simple but yet complicated. alot of prepping needs to be done when hanging the parts in the chroming baskets. its pretty much a science and know i know why they are the best in the biz. Virgil Tripps son was my roommate and we have remained friends for the last 11 years. i guess it was worth it.

    Now this is a very informative technical discussion. And that is why I come here first when researching certain topics.

    Okay, heat treated hard chrome is 65-69 Rc.

    NiB is slightly softer, but some sources say more durable, and it's got about 30% better lubricity.

    Since Spike's uses milspec metals and treatment for their BCG underneath, and they're cheaper than FZ while being done by FZ, barely more expensive than a non-provenance chrome assy, I'm giving them good marks. I'll definitely get one to test.

    I have an inquiry in with CCA on Isonite/Melonite possibilities.

    Nothing on Robar or some of the ceramic penetrations yet.

    Bolt/carrier groups. Top is the early AR-15 and M16 bolt group, no forward assist cuts. Later transitional M16 bolt group is not pictured (mix of chrome and parked parts). Second down is the early XM16E1 bolt group, has added forward assist cuts. Next is the late XM16E1 and M16 and early M16A1 bolt group, now parked (transitional bolt groups are a mix of chrome and parked parts). Third from bottom is the later C marked M16/A1 bolt group. Second from bottom is the M16A2 bolt group. Bottom is the M16A4 bolt group, it is parked a lighter color:



    Stoner intended and designed hard chrome. Parkerizing was a cosmetic change by the Army, for "tactical" reasons, since chrome is shiny.

    Chrome operating mass, combined with this chromed extension, led to almost flawless functioning regardless of sand, muck, carbon.



    As I was able to do several years of side by side comparison of the two types, I consider it very worth it.
