Looking good Si.,

Its appears to be a complete clone of the Maruzen design, any chance of some daytime pics out in the back yard? just gives a better idea of the finish on it, if its good enough i might pick one up and use the Maruzen silencer and outer barrel in it instead.,

ED E

Yeah, I was using the photography bench but the lights are old(like 20yrs) and are knackered. If the clouds clear later I'll stick it on the garden table and get some shots of the trades:)

IS this using normal green gas ?

ED E

Yeah, Ultra-Air and Propane.

Cant get the chrono to read properly, its a piece of sh1te.

Stercus Accidit

Just received my one today, lovely little thing, really nice weight, and seems quite simple internally, after my last niche gbb the luger, thats a big plus in my books.

It seems to de-cock consistently, and lock back consistently. The issue lethal mentioned ie. letting out a bit of gas when de-cocking, doesn't happen with a bb chambered, or at least it happens with such little power it doesn't dislodge it.

Authentic takedown, solid feel, great little thing.

Edit: I have already taken it apart as far as the trigger assembly to tweak a part, after using the safety, the double action didn't always catch the hammer and pull it back, there is a small level in the hammer that catches the sear, I simply gave it more angle to swing through to catch more. If anyone has an issue with double action not catching the hammer, I'll post up pics of what I did, hopefully you won't need to.

Have you worked out what those tiny bits in the bag are for?

Also, I cant manage to get the gas chamber out

They are for yore ma.

My bits were too big.


I havn't had a look at them, they are o-rings and so on, I am gonna concentrate on a crisper snap on my hammer and a few extra fps, I got 190 with .25g's, whatever that is in joules.

Loverly brapper tho, I feel very suave, shaken not stirred and so on.

Inari

Could you do me a favour? I'm interested in the PPK, and was wondering A) If the barrel is threaded, and if so, where you can pick up the piece to allow you attach a silencer. Reason I ask is AirsoftEire carry the outer barrel + silencer...but if the barrel's pre threaded, I hold a hope to be able to pick up the piece + a silencer to fit:)

ED E

It is threaded, havent found a silencer yet.

Harakka

Got mine yesterday, unfortunately not so lucky. Gun is not cycling, slide locks back everything seems fine but won't cycle. Have been trying to discover the cause without much luck so far. On the silencer front, Redwolf are selling off the silencer/barrel combo for $19.50.

Stercus Accidit

Might be the slide catch?

Pull down on the trigger guard, and pull the slide back and up to take it apart. The slide catch is on the left side, check it has its little spring arm pushing it down.

Checked that, it seems fine. Locks back with mag inserted; remove mag, stays locked until released. It just won't cycle the slide when fired. Has me baffled tbh .

Have you got bbs in it? If its empty you have to remove the mag, pull slide, re-inster mag. You cant just cycle it empty like on an M9 or something:)

Yep have tried it with bbs, fires the first bb and thats it, slide won't cycle to reload the next.

Sounds very much like the slide lock spring isnt sitting right. Its tricky to fit, but without it working the slide lock can engage with a full mag.


Its the bare shown here below the chamber.

Harakka

Just tried it with the slide lock completely removed, exact same as when its in place. When it's fitted it springs back down when you manually lift it so I assuming thats correct - flat side of spring at the bottom. Just noticed that the loading nozzle is moving freely back and forth, that's not right is it?

That is fine, they are designed like that.

Could be simple friction or something catching, or as lethal said, the return spring. Where are you based, a shop techy could sort it I'd imagine?

Harakka

Must be something like that, as I can't see anything that could cause it. It works fine when racked manually. Probably will have to go that route, but I'm in Kerry so no-one locally. Gonna try and track down a copy of the maruzen manual first might give me an idea, thanks for all the help .

Stercus Accidit

Good luck with it. The default questions, are you filling it with gas with the can upside down, and are you using green gas come to mind? I imagine you are though. Check for burrs on the slide rails, the paint is a bit caked on in places on mine.

Keep at it anyway and try to figure it out, let us know how you get on.

Harakka

Yes to both the gas questions. Have also had a look at the frame and slide and can't see anything that could cause the problem. When you rack it the movement is fine, no resistance or snagging. I did notice that the rearward movement of the slide when fired is only a few mm so something definitely not functioning right. Thanks, will keep working on it.

Stercus Accidit

Maybe the hammer is light striking, could be a stiff valve on the mag. Spray some silicon oil into the opening and around the striker valve itself while thumbing it in and out, may help.

ED E

Do you have a chrono?

I'm thinking gas chamber issue.

Harakka

Yep, I have. I didn't even think to chrono it ; but I'm thinking along the same lines as I've tried most everything else I can think of. Considered light striking after what Stercus said so stripped the mag and valve and cleaned and oiled the striker valve but it's still the same. Will chrono it later and post the results, hopefully it will be a step towards sorting it!

Stercus Accidit

Can you post an image of the striker valve and the rubber gasket on top of the mag?

There are a couple of possibilities I have found from messing with my one that could be the cause.

Will try and get a couple of photos of those up soon. Just chronoed it, ranged from 174-211 over 5 shots on green, something definitely not right.

Harakka

The best shot I could get of the valve:



The o-rings on the valve are fine, despite how the photo looks

ED E

Did you open the top piece? That spring is sitting vertically, it should be horizontal.

Also, I'm having leaks from my fill valve, the rings started to fall apart as I pused them out. Gonna grease it up now and see if I cant get a good seal, then to try the chrono again.

Need to get myself a new gbb so looks like it will be one of these babys
Whats the accuracy like on them ?

Thats something I'm about to do. Got some KJW targets here, I think 8m is a good range?

Damo 2k9

Sounds good
Report back to boards hq :P

Highest chrono reading:.32J .........:rolleyes:

How is it so low?

Think we have a breakthrough, its been like that since I got it, I did open it but never thought of changing the alignment of the spring. Going to change it first thing tomorrow and see what happens. Thanks for the help

Top of the mag is wrong I think.

Take off the clip holding down the rubber gasket.

Take little plastic frame out of gasket.

Take out brass tube and spring.

Put them in so the spring is at the back and brass cylinder at the front.

It should cycle now.


When you re-install the striker valve, put it in so the brass is flush, then in a little further, not until it stops turning.


Alternatively it could be that the striker valve was over tightened, and you don't need to change the gasket assembly at all.

Try adjusting the depth of the striker valve first.

Harakka

Quick update. You're were both spot on about the top of the mag. Refitted as you said, Stercus and tried it, cycled fine! However, thats only half the story. After firing two rounds it was back to square one, that's when I heard the rattling in the mag, took it apart and the upper piece of the fill valve was bouncing around inside :rolleyes:. Still trying to get it sorted, about to give up on the mag as a lost cause. Going to try and get a Maruzen original.

Stercus Accidit

You can reassemble the inlet valve unless it broke.

ED E

Mine's been leaking again. I thought it was the fill valve. After I takedown and reassemble I've found it isnt. Its the seal on the base plate:eek: Goddamnit.

Stercus Accidit

Little bottle of brake fluid, soak the rubber for a half hour, retry.

It engorges the rubber, car brakes cant afford to leak you see.

Dex told me that one ages back, and its always worked.

ED E

I reseated and greased it to see and it worked, I think. Pretty sure there's no leak but I'll submerge it later to verify.
