    Parallax Tactical Gen2 TIN Bolt Carrier Group

    Parallax Tactical has had these TIN carriers available for awhile, but I thought I'd post here as we have quite a few Nickel Boron fan and they've released their lower cost Gen2 version. Parallax Tactical first has the carrier coated in Nickel Boron. Then polished, before getting it sent out to get coated with TIN. In addition to its beautiful gold color, TIN gives the Bolt Carrier Group one of the hardest surfaces possible. Titanium Nitride pushes the hardness level above Rockwell C hardness of 88. Parallax Tactical uses high quality mil-spec Carpenter 158 bolts to ensure reliability. Visit Parallax Tactical here to order.


    Description:


    Parallax Tactical's Titanium Nitride Bolt Carrier Group is an 8620 steel bolt carrier that has been coated using a technique called cathodic arc PVD, or physical vapor deposition. This bolt carrier group is completed with a Nickel Boron coated Carpenter 158 bolt and 4130 steel cam pin.

    TiN is an extremely hard ceramic material, often used as a coating on titanium alloys, tool steel, stainless steel, carbon steel and other metallic components to improve the substrate's surface properties. Common applications include aerospace parts, military components, medical implants, cutting tools, industrial parts, manufacturing dies / molds and dental and orthodontic appliances. TiN is a beautiful gold color and is often used as a wear resistant alternative to elemental gold plating.
    The Carpenter 158 steel is also Magnetic Particle Inspected


    Benefits of TiN coating:


    •Hard, scratch and wear resistant
    •Lubricious, corrosion and chemical resistant
    •Beautiful gold color
    •No appreciable build-up to interfere with firearm operation
    •Cost effective alternative to Gold plating


    Specifications:


    M16 Carrier 8620 Steel
    Milspec Carpenter No. 158® steel
    4130 Steel Cam Pin
    MPI Bolt (Magnetic Particle Inspected)
    Gas Key Hardened
    Grade 8 Hardened Fasteners
    Key Properly Staked



    MSRP: $199 Blems also available.

    I've heard of several occasions where someone ran a TIN BCG and it ended up damaging the "softer" components it comes into contact with. Over time mind you, but that would be components like your FCG...

    I wonder how a NiB coated FCG would fair though. I would think better. Either way, I'd be eager to see a long term eval.

    Just a small clarification I received from the owner of Parallax Tactical:


    "the PVD ones are Gen1, the CVD ones are Gen2. Easiest way to tell is the polished ones are Gen1, PVD on top of NiB on the carrier. The Gen2 are CVD (What the new Salient BCGs are.) So the Gen2s don't have a mirror finish, the newest ones have a burnished dull gold finish (by popular request.)"

    In case you're wondering as I was, PVD (Physical Vapor Deposition) and CVD (Chemical Vapor Deposition)

    PVD uses physical processes only while CVD primarily uses chemical processes
    PVD typically uses a pure source material while CVD uses a mixed source material

    Sorry :)

    I went ahead and threw down my money for one to test it out and put a little abuse on it.

    What would you want to run as far as bolt in this setup.

    It says on parallax's site that their complete TIN bcg has a nickle boron bolt.

    So im assuming you would want to do the same ? run a nib bcg, and im assuming a nitride coated bolt would work here also?

    2nd part of question, good priced bolt setup to run with this TIN setup?
