Dboys Kar 98
 

I got a new K98 yesterday and i know nothing about it, but I managed to lose the manual, and I dont know how to adjust the hopup, i think i see an allen screw that may be it, but i dont want to start messing with something im unfamiliar with untill im sure

also, the shells only eject about half the time

and it will only get 2 shots off a fill of gas...

everything worked fine yesterday when i picked it up...

I heard the hop-up is under the rear sight

I heard you have to adjust the hop-up with your mind

That is correct.

Be ready to buy new bolt assemblys, or at least have 1-2 spares. The Shell extractor wears VERY easily, and the shells will get stuck in the chamber.

Oh and also be ready to buy new shells like they are water, you drop them on ANYTHING and they dent enough that the rounds get wedged inside the shell. Or they are too lose and they dont stay in the shell so you end up firing blanks.

yes seems im buying a spring bolt anyways, i cant get more than 2-3 shots off of propane, though i could get like 10 off yesterday, and the bolt isnt leaking...
do they make steel extractors so they dont wear so fast?

No, Ive looked into Real Steel ones, and without serious modification, It wont fit.

Shot for shot, its very inconsistant. The primary culpret is again the shells, I find that they are only "fairly reliable" out of the box undamaged. Once cycled, dropped etc etc The shells become very inconsistant at best. The Orings inside the shells are most likely the cause of your problems.

Edit: Mine was the spring version. I never tried the gas cylinder, but considering the size of the bolt, I dont see how you can really shoot more than a clip before having to gas up. Either Carry multiple "gassed up" bolts on you or a propane tank. Neither which I see are viable options.

ugh my hopup is messed too, the BBs go 50 feet then veer right and down at like 60 degree angle, wow sure glad i gave up a perfectly functional SAW for this...

Never had issues with the hop up. Just be aware, that Inconsistant FPS is usually the cause of your shots differing from shot to shot. Chances are again, its the airseal in the shells causing the issue, not the hop up itself.

As for right and left, clean out your barrel. Theres no reason why it would veer right or left mechanically.

do you know if the spring bolt will work in the gas version of the KAR? are they compatible?

99.5% sure. I had every intention of picking up the gas bolt for the summer games.

From my understanding, the only difference is the bolt. And Mechanically and practically speaking it would be extremely stupid of them to waste money on two different designs if they didnt have to, not to mention "unchinese" of them lol

yours has a spring bolt? how's it work? good?

I no longer have my k98, but i had to do some modifications to fit a real steel scope mount so I could mount a scope (which the scope still was way too far foreward, was hard to aim properly) and I had a real leather issue sling for it.

I used it over a year ago during my lvl 2 certification at the clinic, I came in with 25 shells, walked out with 21, of which 7 were no longer functional. I had the real wood version and I was really attached to that gun, but the issues it gave me were enough to make me give it up. Considering the Shell Ejecting Issue, It would have been REALLY nice if the unjamming rod was real. Woulda saved me GOD knows how much stress trying to get jammed rounds out.

She was shooting very consistant and straight with brand new shells though. Even though some shells (even new) would get jammed due to the worn shell extractor.

Lucky lucky, I'd love to pick up one of these for wall hanging or for taking photos at WW2 events.

mine jams while chambering shells as well as extracting them, and often the shells dont pop out, they just sit there in the chamber looking at me >.>

sounds like you have a worn shell extractor as well.

Wow, sounds like this gun is just full of troubles. You traded a SAW for this??

Made by DBoys.....nuff said...

tru TC, but the rest of the gun is VERY solid. If you had a steel machined extractor and better quality shells (easy and quick to make on a lathe + add some co2 grade orings) It actually is a VERY good gun.

If i had access to a steel extractor and good shells, I would have never let it go.

Keep in mind, im a quality whore, nothing i own is TM quality or less, so for me to say this about a clone is a BIG DEAL for me.

what is it a clone of? i didnt know there was any other shell ejecting KAR

marushin.

so would a marushin shell extractor be better? im guessing they're impossible to find?

Could always contract someone to make a custom extractor lol

I had one once..
 

Adjust the hop-up by flipping up the rear sight.
To make a custom more accurate hop-up and ONE piece barrel can be accomplished with a keen mechanical aptitude and lots of patience.
-I had one drawn up but, since I sold mine I didnt decide to keep it..sry
If you reload with the muzzle pointed down its less likely to jam.
File down/smothen out the gouge marks in the shells as they become weathered from use, it helps keep the shittier ones cycling.
The biggest performance inhibitor is air leaks. Its a better re-enactor functional prop, than a game ready piece.
Sell your soul for a tanaka, you'll like that much better!

+1 on the Tanaka. The gun rocks out loud. Ask Lawdog how i pegged his knee with iron sights at like 100ft with that gun and while wearing a full face mask at Flagraiders.

In the end of these problems for potential buyers who want k98 here's my recommandation:

Are you going to skirmish with it?
Yes -> Tanaka
No -> Yugo M24 Mauser 7.92X57mm (firearm)

Are you going to shoot someone with it and expect they come out relatively unharm?
Yes ->Tanaka
No -> Yugo M24 Mauser 7.92X57mm (firearm)

Do you have a firearm license? PAL is sufficicent
Yes -> Yugo M24 Mauser 7.92X57mm (firearm)
No -> Tanaka

Are you willing to pay big bucks for a k98?
Yes -> Tanaka
Maybe ->RC (Russian Captured) Mauser k98 7.92X57mm
No -> Yugo M24 Mauser 7.92X57mm (firearm)

Here's the price list for those who don't know:
D-Boys k98: $375-425
Tanaka: $1000
RC Mauser k98: $600-1000
Yugo Mauser:$350

sry gotta say this.


Back on topic. Shells will dent really easily. and apparantly the real 7.92X57 shell casing is more solid than the D-Boys one..conversion is gonna be near impossible.
Shell extractor is crap, it wont always eject, basically when you recharge the gun, pull the bolt back half way, if no shell is coming up, push it all the way in like you would to close, and let it loose as the spring would push it back. Let it slide back to 1/2 way, see if its out, if not repeat. (some shell will take 10 times to get it out) as for the piece holding the bolt, email RSOV they can sell replacement for $6, I purchase it before from them. Finally, the shell needs to be lube or it will jam, use silicon grease, lithium grease works too. Appply enough to get the slipperly feeling, but not visable.

either become friends with a machinist, hang it up for looks or lose it. Those are really your options.

I just put some silicone oil on the shells... and all problems went away.... I fell reall stupid now...

you should only feel this way cause you bought a Dboys Kar98k to begin with :p

TANAKA FTW!

but really, glad to see that you got it fixed. is this fix only with regards to shot accuracy? what are you going to do about the shell ejecting issue?

no, this is the shell jamming/extracting/ejecting issue, done 20 cycles without a hitch now, the hopup seems to be fixing itself...

how can silicon oil fix all that? http://www.airsoftcanada.com/images/..._confused2.gif

I imagine the shells had to much friction on each other aswell as the extractor.

ah good. point. i never thought of that.

silicone oil also engorges the orings, reducing air leakage.
Its a temporary fix, but you cant keep oiling everything on the field. Nor (personally) do i like to handle oil covered shells. Call me prissy, but thats just me.

Nice find, they are not much good for gaming and the rounds are costly but it's still a K98 and the best version Dboys has to offer (Gas/Wood)

The extractor design is a poor one, its not grabbing the base of the shell well thats why.

But Honestly, you really should get a real k98, not an airsoft if all you do is plink. Surplus ammo are still available, its not too bloody expensive.

well i found out why it dont shoot for shit, the hopup is torn to hell... no clues where to get a new one...

you'll have to make one, and get a one piece inner barrel.

one piece? the one in there is two piece? how is that even possible?

Get a hopup rubber that is the right thickness/consistency of your old torn one, maybe slightly softer. The two piece inner barrel has different diameters, scrap them thats why its will shoot 3/5 decent shots.
Measure the length of your 2 piece inner barrel and cut and machine/order or buy and install the new one piece inside your K98 and you'll have a much better working rifle

I didnt notice any seam or anything in my barrel when i took it apart, are they all 2 piece? and like i said, how can a 2 piece barrel even work?

well, still not sure what is meant by 2 piece barrel, but i made a new hopup, going to test

Where did you get your kar98 cause I have been looking for one

Probably in the classifieds.

The dboys is a piece of junk; however, i found an interesting thread on how to make it into a decent springer (no more shell ejecting); it requires a lot of work and a VSR-10.

Yup, that's what I am going to do with mine sometime in the future.
