WE Gas Blow Back M4A1 Carbine

[redline]

WARNING!! Guys, I just recieved the Knight's style trigger guard....and it broke my lower reciever. I don't know whether I'm just dumb or what, but I've replaced the trigger guards numerous times on various AEGs and even real steel..but either the trigger guard was off or just bad luck.

 

As I was pushing the pin through, it went through the first hole just fine..techinicaly the guard should have been alligned since the front end was already hinged in. I'm guessing the quality of the hole on the trigger guard was off, causing the roll pin to come out the other end at a slight off angle, missing the exit hole of the lower's other side. I tapped it down, but felt it tighten. I kept pushing and "ping!"..the other side of my lower broke off.

 

I put the stock trigger guard back in (fit just fine) and used metal epoxy to glue the broken part back onto the lower.

 

Totally bummed. Anyone have succuess with that aftermarket trigger guard?

Bloody hell mate!

You're not having much luck at the moment

[yehaw]

Same thing happend to my PTW with a real steel magpul trigger guard .. i broke my receiver. So i just bought a PRIME lower and installed it without any problems then.

So it's not necessarily the trigger guard.

 

Anyway, you should use your pliers to push the pin through .. don't tap it in with a hammer.

The trigger guard I bought was supposedly for the WE...so

Yeah, I know. Tell me about it.

[yehaw]

i'm just saying that even RS parts are sometimes a tight fit.

 

it's also possbile that the receiver is out of spec (0,00X inches might be enough) so that this

techinicaly the guard should have been alligned since the front end was already hinged in

isn't the case.

 

 

 

And because WE and Systema have a die-cast receiver, they tend to break much easier than a PRIME receiver which is CNC'ed out of one solid block of aluminium.

The same happened to me with a STAR M16A3 body, since that i use a pair of pliers too instead of the hammer for that kind of pins.

My new steel nozzle assembly

 

 

 

Three out of 4 braze nozzles from 4 WE AWSS in my team have been broken. One guy broke twice before switching to steel.

[accuracy]

Accuracy,

Mine has it too. Not as dramatic (or oily) as yours, but if you look closely at my right side mag well, you will see the "2 color" thing going on,

 

ROTTO

 

wow i'm surprised someone else had this problem.

 

maybe it had something to do with their annodization process.

 

btw- is that a RS 551 on the WE?

 

 

 

Mmm...well I'm kinda annoyed now! I wish I never asked

haha

 

i hope yours at least wasn't carelessly put down on a rough surface.

 

Mine came out of the box looking like this, so it most surprised me.

 

i was just relieved that at least the deflector on the receiver wasn't scratched as well.

PM sent.

 

If these o-rings are so rare and difficult to get, perhaps you could send (or sell) spare-ones... Just an idea.

I think these are rather critical for optimal functioning of the gun. OK, other o-rings are there for a purpouse too of course, but most of those are available it seems.

 

Can someone tell me if the dimentions of these o-rings needed on the "A and B type Steel Nozzle Assembly, NOT the "CO2 ready ones" are the same dimentions of the original WE part #45 ?

 

I really hope Wetti will be able to help us out here.

 

Thanks in advance!

 

Reply PM sent. But in fact that particular O-ring is NOT a critical part. Many customers here who's running the gun on low power would voluntarily take off that o-ring for netter functioning. That front o-ring is there to provide extra sealing only; the gun can function perfectly without the piece.

Well I was a bit disappointed with the initial condition of mine.

Lots of wee marks and scratches all over the receiver, all stuff that would probably happen anyway but a bit annoying.

 

Plus the forward assist was missing and on closer inspection I discovered the forward assist spring was missing too!

 

The guy in factory who was responsible for that part was slacking that day

 

EDIT.

On another note I have decided to attempt the inner barrel change for the first time today.

Is it just me or is really tough to get the short barrel back into place?

I guess AB gets the Steel Nozzle Assy's from TS-1? And I read even TS-1 didn't send out the o-rings yet?

So ALL Steel Nozzle Assemblies sold so far are useless?

I've bought steel noozle assembly directly from TS-1, and it had o-ring.

[newcomer]

Has anyone ever considered using carbon fibre inner barrels?

[Involved6]

Hey WETTI, I did a topic search, but could find no mention of this (at least in the keywords I searched)

I am thinking about making a "VN"-style M16 out of the A3 model when it is released, so I had a few questions:

- Are the upper receivers able to be interchanged with real steel ones?

- Are there plans for a VN/SR25 "Short Mag"? I know that the super-short mag project was canceled, but have heard no mention of VN mags

- Is there any "maybe next year", etc. Information that could be given about a VN model? To modify the A3 to a "true" VN version, I am looking at almost $250 additional dollars... I might hold off on such a project if there was even a slight chance that one would make it out eventually.

 

Thanks!

I just learned how to disassemble "everything" (except lower receiver) because I wanted to see what kind of hop-up I have.

 

It looked tough but it went rather well.

 

Look here for a takedown guide:

 

WE M4 GBB takedown guide

 

When putting things back together, the only thing I had to find out by myself was putting the gas-tube back in.

You need to turn the delta-ring so the opening is on the upper side, and one has to turn the delta-ring-spring so it's opening is on the upper side too, so the gas-tube can pass both and can get into the opening in the upper receiver.

 

Succes!

 

 

 

P.S. Something completely different, and perhaps Wetti (if he finds the time :-)) can answer:

 

My WE M4 has a metal bolt-lock (a magnet sticks to it, so I presume it's metal?), but the hopup is still old version.

 

What 'version' would this M4 Gbb be? A 1 1/2 ?

Edited April 12, 2009 by lukvdh

[lukvdh]

Completely off topic:

 

anyone (Wetti....?) knows if WE is planning to make AK GBBs too?

Thanks for the PM.

 

And thanks for this info on the o-ring.

I tought all pressure would be lost if the o-ring isn't there.

Again learned something new :-) !

Oh dude. I just ordered one.... So I guess I gotta be really careful with this.

 

[jkpics]

If you hit it with a hammer it will break, airsoft guns are like that.

Hi Accuracy

 

Yes, it's a real steel #50sc a.r.m.s. SIR - bi-level (new model).

 

If you take that front upper rail off (like I did in the pic) the eotech lines up with the iron sights.

 

Bolted right on with no mods. And the color is right on the nut.

 

 

 

[4boost]

I have some slight color variance as well. You might want to try a basic soap and water cleaning on the receiver (be sure to uninstall everything from the receiver so that all you have is the receiver itself) and then wipe it down with whatever silicon oil you are using (I use RC shock oil). Once you have a uniform coat of oil on the receiver (nothing seriously thick, just apply the oil to a rag and then wipe down the receiver) , take a clean microfiber cloth and buff the excess oil off. That should give you a nice uniform and deep black. The color variance is still there but you'll have to look for it.

[rottenotto]

Thanks Boost

 

And the big thing is the microfiber cloths....accuracy.....a microfiber will mop up all that grease on your rifle like it wasnt even there.

 

Your gun will have that nice dry, matte, anodized appearance again.

there are some new spare parts available @ airsoftbuddy:

Could be anything up to the last 'ver' that uses the brass nozzle.
