WE Gas Blow Back M4A1 Carbine


Recommended Posts

I'm not sure how your logic works,

NPAS is a flute valve, it sits in the nozzle.

last time I check, nozzle must be able to seperate from the hopup chamber so that bb can be insert into the barrel.

I think that answers your question

 

No, this did not answer his question, it was useless...

 

 

 

 

yes, NPAS has nothing to do with the adjustability ot hopup

 

This response directly answered his question...

I was trying to tell him that he ask a pretty simple question that most should figure it out by logic...and for those who drank to much alcohol the bottom line is there for them.

Attention WE users:

 

I am working on a project with a fellow machinist to start producing some higher quality reinforced parts for the WE gbbr series. In order for this project to get started we really need your input, ideas, and support. As of right now we have a slightly modified and stronger metal part #59 for the m4 based trigger units all laid out , but we need your interest to finally get it going and for these high end pieces to start being produced. Please PM me if you would be interested in such a part

.

Also please post or PM me with other parts you WE users would like to be made. I know Ra-tech and CWI have come out with a few upgraded parts, but have heard mixed reviews on them, so I would really like to know from you what changes need to be made and exactly what parts specifically would you like to be reinforced and produced. For starters we are only looking at putting together some of the smaller parts, so sadly no complete bolts will be on our schedule, but maybe with your support and ideas you can help that become possible sometime down the road.

 

Thanks,

 

COBB

As my M16A3 is out for delivery today, I am trying to think of everything I need to do first before I start loading and shooting; I have read many different variants of maintenance methods for the various WE platforms, and although the methods use different brands or lubes and cleaners, they all seem to follow a basic principle...maintain, maintain and maintain. Do any of you have a link to a tried and true maintenance procedure that is known to be an excellent care guide for WE gas blow backs?

 

I'm looking forward to disecting every piece and cleaning and lubing it all back together...

I took my M16A3 and chrono'd it yesterday. There was planty of facts to consider, as well as notable issues. Here is video of the chrono test session:

...and here is a short video of a concern I have with the bolt carrier group:

Can I please get some feedback on the BCG concern?

regarding the bcg "issue" some say that its better to sand it down so it doesnt catch while it is retracting. but for me its better to leave it as it is cause its a sign that there is a good tight seal between the nozzle and the hop rubber thus making sure that you dont have air leaks. no air leaks means all gas is going to the barrel.

The mag that came with my WE SCAR leaks. I mentioned it to a retailer & he recommended a dip test.Take the outer cover off the magazine & dip the whole magazine under water & look for the bubbles{incidently i haven't got round to doing that yet as i bought CO2 mags off him}.I did strip my mag to have a look at it before testing & was surprised to find that the whole of the spine side of the mag is removable & held in by screws.Apparently there's a large O ring inside which is very easy to put in wrong.It was recommended that i grease the O ring before putting the mag back together,test it & repeat the process if it still leaked.I was under the impression that it was the top valve that was leaking & i haven't found out one way or another at the moment.I'll have to give that a go tomorrow.

I ve had many leaks from m4 mag. Mostly from the main seal

,Not only that there is more chance of leakage but also orings

Are very prone to splitting up( epic Design fail.rlly). So I developed my

Own way to remedy this problem.

Instead of ordering the same oring as a replacement.

Buy a proper industrial orings of 2 mm diameters (they r sold in metres

In my country)replace the old 1 with those, cause they r

MUCH tougher add some lube and its all set. Mine have had no

Single leak since then. U can also try some mods, (there are plenty of em)

, Gd luck

i also use those big orings too. its a bit hard to install at first cause youre pretty much trying to put a round thing in a square canal. i switched back to the stock ones cause the round orings are too thick and is causing the backplate to bend outwards.

 

theoutlier,

 

can you give me the exact oring size you are using?

 

tia!

DRAGON64, the back of the plastic nozzel part has a O-ring on it, the BCG sits like a cap on that, then you fill the cap with expanding gas, and the nozzel can't go forward, so the BCG is pushed backwards and the nozzel stays forward untill the BCG goes so fare back that it opens the piston cup and the nozzel hits the retening parts, only then will the nozzel move back.

 

Now that you understand how it works you can see that your concerns are meaningless.

its a rounded 2mm diatmeter oring.ofcourse its gonna be difficult to install, but i used the special kind of adhesive (same kind i used to glue the 2 ends of the oring chords together)But i guess u can use super glue?. Few drops of those on the backplate and it stays in place. I also have heard some pple with good result on a 1.5 mm ones. so i suggest u try different sizes. Also to help with the installation, always use superlube on the orings and cclamps to hold the mag together.

 

Others use silicone gasket to seal their mags.

Not tried this yet.

 

Seriously considering swapping over to the 20rd vn mags as the 30rd ones are a pain in the *albatross*.

 

i tried using bare silicone gaskets and had a horrendous results. But it does good job if u already have oring in place such as this one as it seals all the small gaps the leaks could sprung from.

Hi guys. No matter how ridiculous I may sound, got to brig this up: got my M4 converted into open bolt (CO2) and also had to change the mag lips. The OB lips seem not that tall and slightly narrower than those for CB. The default bb loader seems not to work anymore with the new lips. The WE open bolt kit comes with a strange piece of plastic (square with a hole in the center), which I initially thought that would work like some sort of adapter for the bb loader. Well, it seems that I was wrong (btw, anyone knows what's the actual utility of that part?). Question is: how in the world you load now a mag (it seems to me that the bb's are now placed in a single column instead of two)? Any suggestions? Thanks in advance.

I hope you changed the follower in the magazine as well? Otherwise the bolt wont hold open

@ManMarin3: thanks. will try that. I assume you put the pistol mag adapter on(?).

 

@rolling-thunder: I assume the "follower" is the plastic part placed on the top of the spring, which is holding the bb's, right? If that's correct, couldn't miss it as they come in pairs (pls see below):

Yep those are the ones.I've added a picture which i took so a friend could compare Closed Bolt with the Open Bolt magazine parts.

I found the loading tool that you get with the gun to be useless,basically i seem to do what everyone else is doing.I use my standard AEG mag speed loader on an angle & fill the mag that way.
