WE 4.1 Hi-Capa Problem!
 

For some reason, my GBB has a ton of problems and I suspect they all have something to do with the slide.

1: Gas is expelled like there is no tomorrow. The first three shots expel a ton of gas, and then the next shots have next to no gas expelled.

2: Slide doesn't cycle completely when firing.

3: When mag is empty, it still shoots and cycles, but the cycles go like halfway and don't reach the catch, and therefore the cycling isn't stopped.

Any and all help would be greatly appreciated -.-"

EDIT: Also, I just lubricated it, so I don't think its that thats a problem.

Nozzle may have cracked. Very common problem in WE hi-capas.

Thnx for the input! I'm looking into it now.

This gun has been fired a total of 4 mags x 30, so 120 times.
I kinda expect a gun to last at least 400-500 rounds on original parts. -.-"

I just did a quick google search on an upgraded nozzle and can't seem to find any. Could you point me in the right direction? Or is it non-existent?

100% agreed. Sounds like a cracked nozzle. Upgraded aftermarket nozzles that fit Marui will fit WE as well.

Take it apart and check the nozzle for cracks.

I just received a bunch in stock. Message me if you want one, and I'll send you details. Haven't had a chance to post them up in my sales thread yet.

You have been PMed, ILLusion.

Also, I can't seem to take the damn assembly apart without using a method that seems like it would break it. Argh. No amount of googling will do me any good and I have given up for now. Because I am sleepy and tired.

The assembly should just drop right out after you've removed the screw from the back of the slide, and the top of the rear sight. Confirm it's cracked before we look in to buying a nozzle.

The other potential cause of the problem is a non functioning floating valve, but the design is generally very reliable. Chance of failure is very low, but you can check that at the same time you check the nozzle. If you see no crack on the nozzle, then you can go deeper to check the floating valve.

Oh thats how! Thnx!

The nozzle has no apparent cracks.

I think I'm just going to send this back to the place that I got it from because they said that there was a 3 month warrenty for GBBs.

Thnx for all the help and I think that now I have a general idea of where the problem is to be found.

I also forgot to mention in the openeing post: After I expelled all of the gas and refilled it, it would barely fill for about 3 seconds before gas started to leak. Is that a problem?

Yep. That's a problem. It's also probably because it's a WE... but that's for another post...

So are you saying that my mag is a lemon and that I should get it replaced? Or is it easily fixable?

Check one of the few mag sealing guides on this forum. It's a common problem with WE magazines.

Search for "gasket" in the Doctor's corner - look for a thread made by "z0ng", and another made by "coachster"

Ah, thnx, I'm going to attempt a remedy now.

EDIT: On second thought, I'm going to let the peeps who I bought it from look at the whole gun and the mag first so that I don't end up accidentally "fixing" the wrong problem.

EDIT 2: Upon further diagnostics, it cycles fine and locks up fine when the mag is empty, but normal cycling and locking only happens sometimes. Other times, the stuff that I mentioned above happens...

I just thought of something that I didn't think of before.

If the mag is too cold...does that cause a problem? Because after firing off 30 shots, the mag feels just about frozen and then the gun itself starts to get cold. Around the second time I use the mag, it starts to screw up...

This is typical of cooldown effect.

Looks like we'd overlooked it. This is content for GBB 101.

Wait, so it's SUPPOSED to happen?

OMFG -.-

Some guns/setups and propellent types will suffer from it more than others. Firing in rapid succession does not help.

Ah, I see. I just did some research on it, so I see how it makes sense and would happen.

I guess no more than one clip at a time then!

And now that we're finished with GBB 101, let's move on to Firearms 101:

LOL. I know, I know.

But you know what I meant. :D

Time to revive this thread with another problem -.-


If my hammer is not straight and is kinda tilted when looking from the back...does that mean anything?

When I say tilt, I mean that when it's uncocked, it tilts to the left. When cocked, it's tilted to the right...

I don't know that much about hammers, but I'd guess that something that holds it in is loose. This might mean that something has shifted when the gun was firing? (All speculation)

If I helped... then you're welcome :) If not, then sorry I don't know :D.

Also, next time I would buy a TM pistol. You have to pay a bit more, but then once you start buying all of the replacement parts to get your WE up and running with lower performance than the stock TM or even the stock WE, you will end up paying more for a worse gun.

Ah, I never bothered to update this thread lol.

Turns out the mid-frame was cracked.

Instead of creating a new thread, I decide to revive my old one.....

So......problem with gun...
I already googled and search on the forum. But nothing.

When cycling, the slide doesn't always go all the way back to neutral. Sometimes, it just stops like halfway, but it isn't due to the hammer getting caught on the internals.
The nozzle seems to jut out when this happens and it takes some effort to push it back into the slide.
The slide racks just fine without the mag inserted, but doesn't even cycle the first time unless I push the mag into the gun.

Any and all help is appreciated...

Do you lubricate your nozzle/oring at all?

Yeah, I just lubricated the whole gun.

I've also noticed that the hammer takes more effort to cock than it should.

Just read the entire thread. The biggest problem seems to be that you cheaped out and bought a WE instead of a TM.

Its not even worth it in the short run.....I cannot understand peoples attraction to cheap guns. YOU GET WHAT YOU PAY FOR.

I'd sell that POS and buy a TM.

/endrant - alex

Too little too late....on buyin a WE......all I want to do is to fix this POS so that at keast it is usable.

I mean, if I sell it, it won't sell for much, so I might as well just spend a few bucks and a least make it work. And buy a better one after....

You might be able to sell it as a parts gun...

Can you provide some pictures of the guts of the gun? that would help a lot.

Pics of internals. Not really good due to bad camera....and no anti-shake feature...but hopefully you can tell~

So when you have a situation where the slide doenst return all the way forward does a good tap on the front of the barrel fix it? For instance the slide jams half way. If you smack the muzzle it immediately returns to battery?

Nope, it doesn't return to battery if I smack the front. However, if I push hard on the rear, then it goes back to normal.

Maybe the nozzle is jamming up on the magazine?

Check your piston head. I bet it's broken. :)

The piston head seems fine....the oring was slightly unseated when I pulled it out..is that a problen?
Also....should the oring on the piston head be protruding from the head by like 2 or 3 mm?

That's precisely the problem. Basically the oring gets out of place and jams up the nozzle. This results from a cracked piston head or a loose oring. Do you have a pic? There's a "cup" type and a normal oring type.

I cant find my camera for some reason right now....so I looked for it online.

It is this one: http://begadishop.com/catalog/produc...oducts_id=5581

It certainly does not look normal to me....

That's the cup shape. Change your piston head to an oring type and you'll be fine.

Thanks for the help!

Time to fix this dumb problem....
