Well, I finally got out and played today. Had a decent day. The kar shot well enough, but needs work. I need to either talk to edgi about making me a barrel for it or building a high performance VSR chamber for it. Not that the stock bucking could not hop .43s but could not do so accurately enough to keep my shots on target.

I am sure I can fix this, but I HAVE TO BUILD A NEW MAGAZINE SYSTEM FOR IT... This BS of only having 1 mag is absolute crap... reload owned... killed by my own SVD with a shot to the head under the brim of my boonie and just above my goggles... Lemming... still mad bro, still mad... Great shot, but it was my SVD that did me in... GRRR..

So on to the important stuff. I have to start on my HPA magazine system.

So to confirm my own hypothesis that I could use the magazine assembly from G&G for their G980. They will work 100%, after the required modding. Which was part of the plan.

Soon.... Soon....

I have disassembled the magazine.. To my surprise their is a lack of space on the inside of the magazine for your gas. This makes sense when you compare it to the amount of decent powered shots you receive from it.

So far my design for this new magazine is pretty sound, I think. Though its a bit derpy compared to the rest, kind of...

It does, however, fit well into my mantra of what I want from my gear and how I play. The space of the old mag vs. what I am doing, I can probably carry 15 to 20 times the ammo in the same space the old mag takes up, pouch wise, at a fraction of the weight.

I think this is a good start to a awesome build.

So later today I should be receiving my new Gas Paradise CNC VSR chamber. Gas Paradise CNC Aluminum Chamber For Tanaka 98K (Using Vsr-10 Style Hop Up Bucking) [GAP-PT-98H-AG] - US$79.00 : Airsoft Global!, Gun

I'll update when I get home and take some pics. (I know you guys love the new parts smut)

I know what some of you are thinking, "What the hell are you doing?!?! There is nothing wrong with the stock chamber!" Your right, there is not anything wrong with it. It will hop .43s like its nothing. I would be willing to bet it would shoot careful's .66s with relative ease. (Can't test that as I do not have any.)

What I am having a problem with is that it is giving me inconsistent hop. As in, some shots will be perfect, others over hopped or under. So this leads me to believe something is off in the unit. Could be dirty, the rubber is going to crap (this is likely the case), something is sticking or deformed.

Seeing as I own 2 VSRs already, buckings are easily available. (Plus I already have a few.) Also this gives me the opportunity to test the VSR orga barrel I have.

I have heard rumors that the PPS Kar98 magazines are exact clones of the Tanaka. Problem is I have not seen any in stock anywhere.

Hey plaz!

you want to replace the spring and O ring in your hopup with a chunk of O ring which will resolve the "not enough hop" issues you're seeing, whats happening is the edge of the spring or ball bearing are catching on the inside of the chamber, it happens, an O ring will grip everything a bit tighter and have a lot less give overall

I'm interested in that hop chamber, can you take a handful of pics of it with a ruler next to it? i am interested to know if it will fit in a G&G g980

also the magazine looks interesting, i've never had a problem only carrying 8rnds at a time but more is always better right? :)

I'm also fairly certain this is my old tanaka... it makes me sad to see it suffering so

I am not having trouble with the hop up other then it is inconsistent.

Next time I am over at my brother's place I will get pictures and measurements. Though after some studying of the g980 you will need to make some holes in it in order for it to work in the g980.

The issue that I found with mine was that the spring would like to wander up along the ball bearing or get stuck on the threads of its hole which was causing under/overhop, with a rubber stopper instead you basically eliminate that (but it'll change the first couple rounds after adjusting as it settles).

Also probably not with this one but with a newer gun you might want to file the edges of the hammer that hits the valve as that likes to get caught up too

Time to dust this thread off.

Soon my baby will be back to me. Never did get around to installing that VSR chamber. So now I need to find it again and put it in a place I know I will find it.

Now for some additional info.

If you have a Tanaka Kar 98k, and you need parts. Look here.

They have parts for it and other tanaka rifles. They seem to regularly stock them as well. So your welcome if you did not know or looking for parts.

The VSR Conversion Chamber:

I am going to preface this that this info is from another person feeding this install to me and all the problems they are encountering.

This is a bit of a bear if you get one and install it apparently. Its quite picky with nozzles and buckings. You may also need to fabricate your own nub for it. The install was done with a 60 wonder bucking and a Crazy Jet. Tested with 70 and results in jamming. With the 60 its quite sensitive but no jamming.

Ill add more to that once I find and install mine. Finding VSR barrels and buckings is a hell of a lot easier then finding tanaka barrels and buckings.

I have no experience with the Tanaka version of this rifle, but I own the PPS clone of it. Not sure if it's 100% compatible but if the chamber doesnt work out for you, you could try getting a PPS hop up unit. That version uses a normal VSR bucking and I'm pretty sure a normal vsr barrel (though I left the stock barrel in as it was performing great as it was). My only complaint is that the PPS hop unit uses a vertical cylinder as a nub which means the pressure distribution is a bit whacky. Still shoots really nice regardless...

I was looking at the PPS chamber, it looks like it should fit. I know the bolt will after some mild adjustments. Think ill order the chamber bits and bolt. If memory serves mine was rather chewed up.

This is the stock configuration hopup solution in a fair number of Tanaka rifles and clones. https://www.wgcshop.com/products/fal...0-g-g-g96-g980

For obvious reasons, a VSR bucking would simply be better as you have more options for barrels and bucking designs. Though mine will lift pretty much anything pretty damn easy all said. Its problem is with its consistency with applying said hop. Its also far easier to source VSR buckings.

I recently installed a (supposedly modified) PPS chamber in mine (as well as stainless steel nozzle). Far as I remember (been a few weeks and with airsoft out of the picture - Thanks Covid... - haven't had an opportunity to take it out) I've installed a bucking with a... let's call it older style patch and a crazy jet barrel. Works well, though the hop is set to quasi 0 to lift .45s. Very consistent all around. The only issue I have now is the following:


I have 5 mags:
1 original (from Japan, gun is from around 2002): shoots perfectly just slightly below the limit for fielding
1 from Germany: shoots slightly less than the original but consistent
3 from Italy: all three shoot way lower then the other 2, I've gotten them up a bit by fiddling with the valves but no luck getting them all to shoot the same...
