【TAIWAN T-N.T. STUDIO】How to disassemble SW Kar98K & replace T-N.T. upgrade retrofit kit

[@imvisier9925]

Some quick notes I would like to make for anyone looking to do this, after having done the procedure myself. When you first install the spring that comes in the packet it is horribly stiff. I am talking next to impossible to pull back, or even to install the cylinder head over, unlike this video where the spring appears quite normal to operate. Do not get disheartened like I did, this is normal. After leaving the spring in the gun for about a week and coming back to it, the spring has "broken in" and is now quite managable to pull back, while retaining the stated FPS. Also, disassembling the forward assembly (4:00-4:30 in the video) is not actually necessary to install either of the 2 upgrades. Lastly, the retrofit upgrade kit now actually comes with the hop unit already installed on the barrel, so you do not have to mess with the screws yourself as advised at 22:00-22:20 in the video.

[@imvisier9925]

@@MInsoLim7 Not exactly, as pulling the bolt handle up or down has nothing to do with the spring. However, pulling the bolt all the way up in order to be able to pull it back became something that had to be done with intent instead of being able to just tap it up and let the inertia do the work for you, as the very last bit of the bolt's upwards travel pulls the bolt ever so slightly back against the spring (in the real Kar98k this in effect cocked the gun) so you have to force it to counter act this. However after the spring broke in, I find that as long as you 're mindful that the bolt needs to go all the way up to be retracted, it actually takes next to zero extra force to force it completely up. It just doesnt happen automaticaly with the slightlest tap on the bolt head like before.

[@imvisier9925]

@@MInsoLim7 Another thing I have found is that after installing the new sear, you really need to be fast and violent when pulling the bolt back in order to engage it and cock the gun. If you try to slowly pull the bolt back with uniform power distribution throughout your pull, the bolt gets stuck just before the sear and you are unable to fully cock it. You really need to pull back with intent and determination as well as agility, something that was not required with the original sear. However this shouldn't be a big issue, as since the upgraded spring is quite strong even after being broken in, a hard pull is required anyway though I have still found myself trying to slowly pull the bolt back a few times, only to have to release it and try again with more oomph.

[@imvisier9925]

@@MInsoLim7 Looking at the video Im pretty sure the hop nub is on the hop unit when he ramms it into the other assembly. When you first got the kit the nub would have been held in its proper place by a little piece of pealable plastic. That is where it is supposed to stay when you put it in as well.

[@Acemans]

Tbh I was looking to just get the upgrade kit and the kar98 separately since the preinstalled upgraded one sold out but after watching this process I think I'll just wait on restock

[@Acemans]

Nvm I just bought the kit, was actually really simple

[@grinderkorea]

You saved my day. Many thanks

[@AverageReenactor]

Thank you, after 2 years of owning my k98 I finally decided to add the upgrade after the rifle stopped working. It works good now!

[@TAIWANTNTSTUDIO]

Thank you for support T-N.T. products ;)

[@Luchas45]

Hi I'm thinking about buying this rifle and keeping it stock can you please tell me what stopped working I'm hoping it's reliable in the stock form

[@AverageReenactor]

@@Luchas45 for me the stock hopup was terrible, I couldn’t adjust it. Another thing is that the safety came loose but other than that it’s a great gun

[@AverageReenactor]

@@Luchas45 another was the o-rings inside the stock compression tube broke apart and gunked up the rifle

[@AverageReenactor]

But that was because I used real gun oil on the gun

You're welcome ;)

[@mercAltiar]

Hi Jackie, thanks for the really informative video, the instructions and information have been super handy. Currently stuck around 18:15 where one re-installs the trigger. Pulling the trigger doesn't appear to be engaging the sear allowing the piston to be released enabling the gun to be fired, I've checked and the sear is correctly installed and none of the springs are missing. I am using a higher power spring (~470 FPS w/ 0.2s). Any tips for resolving this?

[@TAIWANTNTSTUDIO]

Hello, recommend check all install steps and re-install correctly all the trigger parts again, if pulling the trigger and doesn't released the piston like 18:55, please really pull the cylinder to the end again and pull the trigger, thank you :)

[@mercAltiar]

@@TAIWANTNTSTUDIO Thanks!

[@micayahc.wilson8061]

Does this work for the SWIT Kar98k Another Version as well?

[@TAIWANTNTSTUDIO]

Sorry, this upgrade kit only for S&T Kar98k old ver. , not suitable another ver. , thank you :)

[@stinkybingus_shellshockers]

Not sure if you guys will see this since the video was uploaded 3 years ago, but is the piston 45 or 90 degrees? I'm having trouble finding what type of piston comes in the gun.

[@stinkybingus_shellshockers]

Could I buy a vsr 10 piston and fit this inside as well? Same with the hop up chamber, I've heard that it's all vsr 10 compatible.

[@S.Lice321]

Hello, all the upgrades can fit into Real Wood Snow Wolf SW-022 second version of kar?

[@TAIWANTNTSTUDIO]

Yes. It can be installed.🙂

[@feridoritos1234]

Is the inner barrels for example Lambda , PDI , Prometheus VSR compatible?

[@TAIWANTNTSTUDIO]

Hi, this kit is internal upgrade kit for improve durability and extend service life, not HOP-up unit, so it doesn't matter what brands of inner barrel you used, thank you. :)

[@FadedMars2024]

Will T-N.T. be making upgraded internals for the S&T Kar98K new version?

[@TAIWANTNTSTUDIO]

Sorry, currently no plans to making upgraded internals for new version S&T Kar98K, thank you.

[@AverageReenactor]

If I buy the the tnt upgrade hopup do I need to buy the rest or can I just use stock internals and the upgraded hopup?

[@TAIWANTNTSTUDIO]

Hello, of course the HOP-UP retrofit kit and internal upgrade kit can be installed separately, just according to your needs :)

are you bringing out an upgrade kit for the new S&T kar98? the one that takes the ZF39 scope?

Is it possible to change the spring without a full disassembly?

Hi, I have been trying to figure out why my hop up stopped working since I just got it so I went on youtube and found your video which was very informative. However the hopup arm fell out while I was adjusting something, any advice on how to put it in? everything seems to work fine, I just wanted to know about the arm and how to correctly put it back in with the other small parts in there.

Hello, it's not necessary to remove the HOP arm during the normal installation/disassembly process, if you want to check the parts please check with your user manual / parts list, thank you :)

[@Azukaae]

This gun is a very nice and affordable replica of a Kar98k, too bad it has extremely low volume of a cylinder for a sniper. If only someone would make a bore up version of it *wink wink* But I could see that it would not fare well, since from the beginning this is a not very popular of a platform.

[@TAIWANTNTSTUDIO]

Maybe its air volume is not as large as other mainstream sniper rifles, but it can still perform well after upgrading. We will still pay attention to and look for models that we think have potential for the development of upgrade kits, and we are very grateful to manufacturers who are willing to continue to develop more models, and we hope to bring more fun to every who like WWII series :)
