    TNA WK180C Enhanced Upper Lower Receiver Combo.. AR BUILDERS KIT PLEASE

    TNA WK180C Enhanced Upper & Lower Receiver Combo
    AR builders kit please
    Includes all parts needed that are not AR compatible.

    Could you make complete Enhanced upper and lower kit so you just use doner AR for the rest of the parts?

    Thanks

    What 'AR' parts work now? Barrel/gas block, stock, buffer tube/spring, trigger housing, grip? So, Upper, Lower & BCG needed in kit?

    allot of the lpk was secured with bolts i feel like you'd need to include those in the kit aswell.

    It looks like the set of WK-specific parts you'd need in order to complete a WK picking what you can use from your box of parts that used to be your AR would add up to pretty close to the price of a complete WK. Looks like it could still be a win though if you want the TNA-enhanced WK bits or have premium AR parts you want to be able to reuse.

    And of course there's far more on Youtube and the web about building an AR from parts. Figuring out how a WK goes together without starting from a complete WK that I'd by then remember taking apart could be a challenge.

    remember that a wk and mrc is simply an ar180
    there are youtube videos about this

    We have released rifle and midlength gas systems and blocks
    so if you have a doner ar you can use the following

    barrel
    muzzle device
    handguard
    bolt
    most of the lpk
    trigger guard
    all of the buffer tube components (though the spring and buffer are not needed)

    Our enhanced upper includes a new carrier and cam pin

    if you have a doner ar do the following
    figure out your gas system length
    but the tna gas system to support it( you might need to tweak the gas port diameter in the barrel depending on cartridge pressures)
    get a wk external bolt catch
    bolt catch spring
    firing pin/ spring
    safety
    antiwalk trigger/hammer pins
    a couple guide rods and springs,
    guide rod plate (bread slice) and you're golden

    the ar180 bcg is similar to an ar15, if you can build that you can do this
    building the upper and lower is about the same, just 1 different spring on the ar180 bolt catch which is the detent stop of the safety
    believe in yourself, these builds are very doable by home gunsmiths with only a few special tools

    Hate to necro a thread but I just want to make sure that ar15 bolts are compatible with your bcg. Like 100% compatible with no modification

    AFAIK AR180 and AR15 bolts are 100% NOT compatible.

    EDIT: I have no experience with TNA enchanced upper bolt carrier. But WK and MCR bolts are different from AR15 bolt

    They are not. AR bolts have gas rings and are shaped differently on the back end than the 180 bolts. TNA sells 180 bolts. All the parts that go into the bolt like the ejector and extractor bits are AR parts. I believe the cam pin is different.

    It say in the last post from tna that if I have a donor ar I can use the bolt. I just want to confirm with them. I want to shoot my grendel and possible build a 6mm arc and be able to use it. If I can use my jp Enterprise bolt I will pull the trigger on their set

    Any idea when you will receive more receiver sets in?
