    Has this been tested on the WK180-C?

    When will bolts be available for the WK180-C?

    What something says and what something is aren't always the same thing. The website also says it works on the ar15 and Maccabee rifles.

    The problem with this is that the WK180-C requires more gas for the operating system to function than the ar15 or others (Maccabee, Modern Sporter) that use the ar15 operating system.

    The gas port in the WK180-C barrel is significantly larger than the gas port size in an ar15 barrel. Hard to believe this barrel will function in both platforms if it's available in only one gas port size.

    This means one of two things:

    Either the gas port is the smaller size (ar15 compatible) and will have to be drilled out larger if you're installing it in a WK180-C.

    Or the gas port is the larger size (WK180-C compatible) and you will be required to use an adjustable gas block if you're installing it in an ar15, Maccabee or MS.


    TNA should be knowledgeable of this as they already worked with MRA to make a new 223 wylde barrel. Here's a quote from TNA in their forum:

    This barrel is specially made for the WK-180c (uses a larger gas port and carbine-length gas system, not easily found on a production non-restricted-length barrel anywhere else)

    Anyways I'm sure hoping TNA could provide some further clarification. I'm really hoping they make the 7.62x39 WK180-C a reality.

    It'll fit alright but it's useless until a 7.62x39 bolt is made

    I was all excited when I seen they announced and mentioned WK180-C builds in the email notification ... then realized, after some searching they're still no bolts so, poopy

    For the immediate time being you will need to open your bolt up on your own.
    By Christmas we should have 7.62x39 bolts for the wk180c available for purchase

    As for the gas comment, these barrels are specked with a 0.090 gas port idea for a direct impingement system.
    the effort required to open that gas port to something a touch bigger for the wk180c (only if you have cycling issues) is minimal.
    It seems that WK180c's kinda break-in after 500 rounds or so and require a touch less gas than when they are brand spanking new

    You can prolly open the gas port hole with an electric drill if you're in a pinch.
    the most critical part of these barrels for you WK180c folk is that they are carbine length and the step height between the gas block journal and the chamber region of the barrel is sufficiently small so that your piston system can clear everything.
    We made a prototype with an Anderson barrel and were forced to do a fair bit of machining to move away from the HBAR profile due to the gas piston system standoff height from the barrel
