PPS Kar98 - Mini Review

if it's not firing then you may have lost the tiny spring out of the mag . on the back end of the mag there is a metal piece that the firing pin (hammer ) hits to release the gas,this piece should have a little spring behind and under it and pushing the metal piece upward , on two of my mag's this spring has fallen out , this allows the metal bit to drop down and wont release the gas when the firing pin hit's it .you can replace the spring with one out of a Biro or lighter so it's annoying but no big deal .you should be able to see the spring under the bottom of the metal piece on the back of the mag and feel it pushing it up .the problem is common to the Tanaka magazines as well.

I have one of these on order as well, and I'm keen to know if it's possible to "fix" the spring issue. Do you think it could be glued in?

i put a drop of superglue at the bottom of the spring ,but be careful just a tiny amount is all that's needed.

My spring is still there, sitting quite happily at the moment! I suspect it may be a sticking valve as it does fire, just not everytime - will lubricate the moving parts and see if that makes a difference.

the other thing i've seen is the sprung brass collar at the front of the mag (that routes the gas up into the bolt) can stick a bit and some lube there is a good thing.

Think it was just teething problems, as its all fine now. I got it all finally set up and ready for San Marino yesterday before I had to come up to Edinburgh for a few days. Somehow managed to get the FPS consistently between 340-320 - more by luck than judgement! Will put another 20 rounds through it Friday night just to make sure.

my tanaka has a simmilar problem

all 4 mags have springs in place

the gun fires about 1 in 10 rounds ,
when it dosent fire i get a click, and a TINY pssst sound
when it does fire , i get that nice tanaka CRACK
using green gas mags.
its been like this for 2 years , only just got round to trying it , any ideas?

if i putmy finger on the fireing pin in the magwell (mag out , it does fire forward and hit my finger)

think its some kind of issue with the bolt

any help greatly appreciated

I can't claim to be an expert, but it could be that the firing pin spring is a tad weak and can't overcome the pressure of the green gas. (It may well work perfectly with 134a). I would suggest trying a weaker gas if you can get some, just to prove the point. Then look at getting a replacement spring perhaps.

Nothing but problems with mine so far first time using it today, just putting some rounds through it indoors to try and get the FPS sorted for next week. First couple of mags no problem, then recharged as I noticed the FPS dropping by about 25fps after every shot. Refilled with gas and now it doesnt want to fire - checked the mag and it still seems to be holding gas so looking for another reason. Will fire every one shot in about 10, but not getting any gas for the other 9. Any knowledgeable chaps recommend something for me to try to see if I can get it working??

I received my PPS K98 and have experienced this same problem. Scoured reviews until I found this forum for a solution. I will go and try it out and keep you posted.

Please excuse my lack of technical language but make sure the gas port on top of the mag isnt out of alignment (round brass thing). I have found it can stick at an angle that prevents a proper seal and causes the same symptoms you are having (it should be free to move up and down). Gentle wiggle with a screwdriver and drop of silicone oil solved it on mine.

Also check the post about the tiny return spring in the mags earlier in this thread, glued mine in so not had that problem so far..

I use my PPS at every game as its the only WW2 weapon I have (or currently want!). So far I've found it to be very reliable, though like any gas gun you have to keep the barrel clean and look after the mags.

Hope that helps!

Thanks Muttley,
I will double check the brass ring. It was a slight bit sticky. I have added silicone spray. so far still no luck but will try your method. I have unscrewed the fps control bolt mid way open and all the way open - no luck.

The lever at the back of the mag, where the firing pin strikes is very stiff. The spring is definitely there.

I have found, that the mag has the slightest bit of wiggle room.

I must commend PPS, I emailed them and they were very quick to get back to me and sent very detailed schematics of the bolt assembly with suggestions to try - I have given them feedback and wait for another response.
Cheers

Quick query for those with either the pps, Tanaka or g&g rifles, whats the compatibility with the side rail scope mounts like?

Quick question, will be using my K98 at the Kasserine game this weekend. Haven't used it since last year, will the FPS adjustment have changed at all due to inactivity?? Any ideas?

Its not likely to change due to inactivity but could be affected by different temperature on the day .
For those suffering loss of power or not firing I had one to fix recently and found that there is a long screw inside the bolt that acts as a spring guide for the hammer spring and it became loose and released the tension of the spring causing very low fps or misfires .its quite easy to access the screw , at the front of the bolt is the nozzle and gas router ,this part rotates independently of the rest of the bolt ,you need to remove this front section ,its held in please by one screw in the side of the bolt that sits in a slotted hole to allow the rotation ,remove this screw but do not imediatly pull the front part off ,there is a ballbearing on a spring that locks the front part in place and as you pull the front part off it will jump out so find a clear plastic bag and put the whole bolt in the bag then pull the front off .put the ballbearing and spring in a safe place ,now the main part of the bolt is hollow and inside you should see the end of the screw you need to tighten ,tighten the screw and reassemble the front end ,again put it all in a clear plastic bag so that when the little ballbearing pings off its retained in the bag.

Thanks for the tips Gav, was going to strip it down for a clean, lubricate moving parts etc but will also have a look at the bolt spring.

Its not a wildly complicated thing inside ,the only bit that goes ping off into the distance is the little ball bearing .

After reading the comments on this tread i've ordered my K98 from HKM (£164.00 - i couldn't argue) i think the wait will kill me now! what do people use gas or Co2?

hi all
ive got this k98, where do you get spares from ? also can anyone help out with a manual or a diagram of the bolt the previous owner has lost the spring/ballbearing in the front part.
im in need of a replacement hammer also
cheers sean

PPS themselves never answered my e-mails about spare parts or their proposed zf42 scope. (Jokes on them, I spent the money on a zeta labs scope.)
Dog green1 on here may be able to source some parts if you ask as he stocks the PPS K98.

Some Tanaka parts for the hop are cross compatible between the k98, m700 and some of their other rifles so that might be an option if anyone can chime in wether they would work.

The seal on the underside of the bolt is Tanaka compatible with the m700 and presumably their Kar98

I just got my pps kar98k home. sadly it didnt shoot. the little spring in the magazine is still there. but when i shoot then the bolt will not go all the way forward. it just click. no gas or bb is coming out. any idea what this could be? i tryed to contact the store where i bought it but they havent anwsered yet...

How do I open up the magazine to replace the Co2 bulb?

Oh lovely picture of those mags!!!

I actually got a few CO2 mags but they've been a bust so far. The nozzle doesnt break the cartridge(8g cartridges, not 12g sadly) seal, so they simply dont work at all. Maybe I'm doing it wrong? Anyone got one?
Oh and before anyone asks, they are PPS mags, not some unknown entity making mags on their own. I assumed PPS actually tested these mags to see whether they work as intended, but one never knows...
Now you do get a small gas canister with them allowing green gas to be used, but at 400fps with a regular mags, I only get 180-200fps with the greengas-gascanister. Mind you, you have to charge the gas when the canister is in the mag or you lose a lot of gas when installing it.
There are CO2 adapters that allow loading these canisters(and regular mags?) with Co2 but I have yet to get my hands on one of those(they are all out of stock everywhere), though I think you lose gas when using those.

The gascanisters with that low output seem ideal for very powerful CO2 revolvers like the Gletcher 'Orbital-laser-of-Doom' Nagant though. Need to get a 12g canister to try that. Which, as you already guessed, is out of stock everywhere. (Edit; found an expensive 12g adaptor, cross your fingers!!)
