  1. WK180-C & WS-MCR Q&A

    The WK180-C & WS-MCR platform are exciting new modern sporting rifles that allow many popular upgrades.

    Q&A


    Q. Can I change the handguard on my WK180-C or WS-MCR?

    A. Yes. Many AR-type handguards can be installed into the WK or WS, so long as there is sufficient height inside for the piston gas system. Our easy-install M-LOK handguards are a popular and compatible upgrade.


    Q. Can I change the muzzle brake?

    A. Yes. The 5.56NATO WK180-C and WS-MCR, feature a 1/2"-28 muzzle thread. Any 1/2"-28 threaded muzzle device/fake can will fit on these guns. The 7.62x39 chamberings all use a 5/8"-24 thread measurement, and any 5/8"-24 muzzle device/fake will fit onto the 7.62x39mm chambered rifle. We recommend the use of a barrel clamp or torque tool for the installation. Please note, that some WS-MCR rifles have locktite on the stock flash hiders, to remove the flash hider, applying a bit of heat to it will go a long way. 


    Q. Can I swap the Factory trigger for a TriggerTech trigger kit?

    A. Short answer. Yes, you can install a TriggerTech trigger kit into Your WK180-C or WS-MCR, but to successfully do this, you’ll need to install anti-walk pins and an external bolt catch release upgrade as well. Many aftermarket triggers do not grip the trigger and hammer pins the same as the OEM trigger, thus the need for anti-walk pins. If you choose to leave the factory OEM bolt catch in your system, it may need some minor gunsmithing to have a good fitting of the trigger kit. With our upgraded external bolt catch, you can drop it right in, with no modifications needed. See our TriggerTech installation breakdown for an in-depth look into how to install a TriggerTech trigger kit into your WK.

    Restock of anti-walk pins, expected early July 2021. 


    Q. Can I change the grip on my WK180-C or WS-MCR?

    A. Yes, the WK180-C and WS-MCR design can be fitted with any aftermarket grip that does not have a beavertail. Installing a new grip on your WK or MCR is simple, remove the screw and reinstall with a new grip. We have a variety of pistol grips in Magpul and Fab Defense options in stock.


    Q.  Can I change the buttstock on my WK180-C or WS-MCR?

    A.  Yes, you can absolutely change your stock. Both the WK180-C and WS-MCR platforms come with a mil-spec style tube, this means any aftermarket mil-spec buttstock can fit onto this tube. Magpul and Fab Defense have a variety of buttstock designs and models that are compatible with the WK and MCR, and no tool is needed to install them.


    Q.  Can I change the caliber of my WK180-C or WS-MCR?

    A.   Yes, you can do this, but the gas system needs to be tweaked beforehand. The bolt most likely also needs to be replaced or heavily modified (gunsmith work). There’s good news though, caliber conversion kits will be available soon.


    Q.   Can a dust cover be fitted to the WK180-C or WS-MCR?

    A.   Not really. The WK180-C and WS-MCR systems are not designed to facilitate a dust cover. A replacement upper would be required.


    Q.  Can I use a bi-pod on my WK180-C or WS-MCR?

    A.  Yes, both M-LOK and Picatinny bipod adapters can be installed onto your WK180-C or WS-MCR rifle to accessorize with your favorite bi-pod.


    Q.  How does the WK180-C slot cover work?

    A.  The slot cover is designed to cover the ejection port side of your WK180-C rif

  2. Upgrade Parts | Installing a TriggerTech Trigger

    Here's a short review on how to install a TriggerTech trigger into your WK180-C

    Those familiar with the WK, know that it has a funky internal bolt catch that prevents the installation of an upgraded, cartridge-style trigger group, such as TriggerTech trigger systems. This is due to the extra material on the bolt catch hitting the trigger cartridge directly below the bolt catch pin on the thick webbing that goes around the pin itself. 

    If you wanted to install a TriggerTech with the OEM plain Jane internal bolt release, you'd have to go through the trouble of filing the webbing area down a bit until it fits above the trigger cartridge and can freely rotate. Furthermore, installing a TriggerTech with the OEM trigger and hammer pins will

  4. AR-15/AR-308 Buffer Length and Weight Reference Table

    When building your own AR-15 or AR-308 it's important to use the correct buffer. Buffers are designed with various lengths and weights.  The correct one to use is determined by the firearm setup (receiver size, buffer tube type, and chambering).

    Buffer Length

    The buffer needs to be the right length so that when the bolt carrier cycles to the rear, it stops at the right position. If the buffer is too short, the gas key can crash into the lower receiver's buffer tube mount; if the buffer is too long, the bolt carrier will short-stroke and fail to pick up the next round.

    There are two factors involved in determining the required length of a buffer -- 1) the type of buffer tube (or "receiver extension") and 2) the receiver size.

    Buffer tubes generally come as either of two types: M4/carbine or A1/A2:

  5. Sign the E-petition to Stop Gun Bans by Executive Order

    Sign the E-petition to Stop Gun Bans by Executive Order

    Public Safety Minister Bill Blair has stated his intent to ban various firearms including the AR-15 by 'Order-in-Council.' In layman's terms that means taking your guns on the whim of Justin Trudeau's cabinet. A concerned citizen in Medicine Hat, Alberta, with the help of MP Glen Motz, have initiated an online petition calling on the Government of Canada to put any such new firearms rules, bans, or other changes before the House of Commons for public debate, rather than being executed behind closed doors by the unelected executive. Please clear this text and follow the instructions to sign the petition and add your voice to demand that your views be debated in the open by our elected representatives.

  6. Guide to AR-15 Handguard Lengths, Gas Block Position, and Muzzle Device Position

    Folks often ask us how to select a handguard length for a given gas system, or they ask what barrel length is needed to achieve a desired positioning of the muzzle device relative to the handguard. This post aims to help explain the factors involved and provide an easy guide to designing your dream setup.

    Below you'll see an ordinary AR-15 Upper Receiver with a barrel and low-profile gas block installed:

  9. Installing Hammer and Trigger Pins

    Installing Hammer and Trigger Pins

    Have you ever wondered if there is a right or wrong way to install your Hammer and Trigger pins? It turns out there really isn't a wrong way but there is a way that is slightly better and easier for you during building your lower.

    If you look at the pins, you will notice that there is a small notch in the middle of the pin and another one roughly halfway from the middle to the end but only on one side. The hammer pin will utilize the center notch and the trigger pin will utilize the one closer to the end.

    The center notch will engage the tiny spring that you can see when looking through the pinhole on your hammer. The side notch is where the (external) hammer spring locks into the trigger pin to help it stay in position. For this reason it is important that you install your trigger before you install your Hammer when completing your lower. Mind you it would be quite difficult to install the hammer first and then the trigger but we have

  10. Neoconfection's Fun Gun

    Reddit/CGN user Neoconfection had a busy week and put together this fun gun with the help of TNA parts & tools

    Neo writes:

     have the Keymod handguard, the shooting bag, and the jacket.

    Overall I'm pretty happy with all of it. I recommend those who buy the shooting bag fill it with rice, not sand, because the sand will take moisture and leak through the seams.

    The jacket turned out to be a pretty good buy as well. It seems well-built. Breathes, but keeps the damp out. 

    Like it says on the website, it fits very small, so buy a size or two up. I wear a large most of the time and the 2XL I bought was snug with a light sweater underneath. I wore it to the range today (it was about 6C and sunny with some wind) and was quite comfortable with
