WE Gas Blow Back M4A1 Carbine


Recommended Posts

Hi guys

 

I have been keeping an eye on this forum for quite a bit now, I think that I might step up and order one on payday. Any UK players got one and whom did u get it off?

 

I see that Ehobby now have the in stock for $320 ($80 del) and I have never had an issue in the past with these guys! Or should I go for a deal with Airsoft Buddy $430 with spare mag & custom receiver!!

 

(should I get a spare Part 122 with the order and should I stock up on green or 134a gas?

 

Many thanks for your replys.

 

Order from AB. His email correspondence is slow going but his customer service is better than most retailers. Nab a 5 pack of #122's, you'll need them eventually. The WE M4 will not cycle properly on 134a. Pick up some GG.

Heres my latest custom job, a WE GBBR version of a Colt Slab Sides Carbine. If anyone knows a pla ce that could machine me a proper outer barrel, I would like to get in contact with them and have a pr

Heres my custom WE M733. I have a modified RS Bushmaster upper receiver as well as RS buffer tube, castle nut, stock, stock plate, pistol grip, front grips, front sight, and some various other small b

Hehehe, Im with you Hwagan. I dumped my LM4 like a bad habit a few months ago and switched back to the WE platform. Used the extra money to get myself a trademarked M16, slapped a RS A2 upper receiver

I noticed that the space between the delta ring and the receiver is a bit much, would there be a problem in fitting RS and other delta rings?

 

 

Hi Brian. I have fitted many different style barrel nuts (all real steel) on my WE. All fit fine with no problems.

 

 

Also,....

 

Sorry for the atrocious typos in my previous post. I was typing in a car on a mini laptop!!!

So that means you can fit a systema cnc'd lower on? As stated that the lower is from a ptw, and upper made from a rs

 

I don't know. Don't think upper fitting implies lower fitting, esp. the trigger group.

 

If the Systema upper fits, does that mean, at least for the US folks, a real AR15 upper will fit? Will it work? I'm not quite sure how the brass chamber cover attaches.

What I did to fix the BB's rolling out issue is constrict the Black Breech rubber sleeve using a layer of thin super glue on the outside of the sleeve of the muzzle half of the sleeve, wait for it to dry and put it back into the barrel. The Layer of super glue is just enough to constrict the sleeve and slow the BB before it falls out onto the hop rubber.

AH! There you are.....you did the nice little diagram on exactly where to thin out the green hop piece, correct?

 

But you also had the bb's rolling out the barrel, correct?

 

I recall your user name, once you mentioned the CA glue as your quick fix. I remember reading that way back.

Slu,..

A bad and "un pc" topic, but yes I have a RS upper, and it can be made to work with the WE.

Can't see why it's "un pc",people over in the States have being modding RS uppers for their PTW's for a while now,and as far as i am aware once modded cannot be used on RS firearms again.

Another way to look at this,at least you now know that you can mod the Prime mur-1 designed for the PTW to fit your WE.

Ill correct myself: It can be "un PC" on this forum.

 

The last time I saw people showing/posting/mentioning how to convert real steel RECEIVER parts for airsoft use, the posts were deleted.

 

Wasn't it Arnies back in the day who wouldnt even allow you to post or mention a velocity (FPS) higher than 350fps? lol! Like some biblical law was broken!

If thats the case then question is how easy is it to convert the WE receiver onto a real steel...

 

Differnent trigger group,wrong materials (the upper wouldn't take the pressure).The lower probably woudn't take a RS mag.

The list is endless.But i think this topic is going in the wrong direction.

Suffice to say that if you have the know how and tools you wouldn't need a WE to convert.

The BB does in fact roll out on the highest hop up. I may try this tape mod, but I am not sure if it will fit properly with everything.

 

About the Oring seal, what you are saying is making sense, however, this was doing the same thing when I tried my lower 350 fps nozzle WITH the stock 122 ring. The bb's still roll out of the gun. So I am not sure if it happened beacuse of the pressure. I noticed it only after I grinded down the Hop Up the first time, that the bbs rolled out.

 

 

 

Evil, can you explain the super glue mod further? Does it keep the bb solidly in the gun? Even when shaken around and about? Can you be more specific on how you applied the glue?

 

I am still unsure if the BB is indeed held in at the rubber black sleeve or at the hop up. Anyone sure of either?

 

 

 

 

Hi Kai

 

Try shimming the green rubber piece. Plac a small piece of tape on top so that the bearing can press it further into the innder barrel for more hop. Something like that. get creative like we have to be when AEG hopups arent giving enough "hop".

 

Just curious? With the hop set at 'full on', you still have bb's rolling out?

 

Also place a piece of tape around the barrel where that missing brass ring used to be. Just try it. Ill explain why later.

 

 

Sale-

I undertand what you are saying.

 

But with the Escorts, it was always the interia of the heavy brass bolt and nozzle slamming forward that just sent the bb (any weight bb) down the barrel. If the hop rubber wasnt set high, it would just roll right down and out the barrel in the loading process.

 

As for trapping air on the forward stroke, this is what I have been saying all along in PM's to others regarding #122.

 

The #122 washer has to be smaller than the cylinder - the store bought O-ring is not. And it creates two problems.

 

What it is doing, is slowing down the return (wont return easily like a Nine ball style seal for intance) and at the same time it is pressurizing the cylinder on the return.

 

The back pressure reenters the nozzle vents until the valve slams closed. Then the pressure is forced to escape in other places. Not good.

 

The "same size" O-ring is a static seal that is obstructing things on both the way back, and the return forward. (I would say the reason for failing valve heads)

 

The gun needs a dynamic seal to work properly. Thats what WE gave it. Is there a better design? Probably. But all things considered, the WE seal works best so far.

Phew,

 

Airsoftbuddy shipped promptly but boy has it taken a stressful few weeks to get the customs side of things sorted. That being said I don't have a UKARA membership since I only play events organised by a legal but non UKARA registered site. I would imagine the whole hoop jumping legal process is a lot simpler if you have a UKARA membership number.

IT has arrived :P:P:P

 

Initial visual impressions out of the box are very good i.e. pass the Kleenex. This is a very realistic weapon. Everything is rock solid although the retractable stock has a loose fit. I should point out that this is similar to most AEG standard stocks and I am only drawn to it as it detracts from everything else. I plan to fit a nice VLTOR or MagPul CTR so I am not too bothered. Colt markings are some of the best I have seen on any M4. Magazines sit solid in the magwell without AEG "waggle". Every action must be done with purpose i.e. loading and removing mags, pulling the charging handle, pushing the bolt release etc. I have tried the charging handle a few times and it’s still in one piece so far. My forward assist seems secure at the moment too.

 

Not fired yet and don't intend to until I know I have done everything possible to avoid all known issues. So I have a few quick questions for the chosen few with knowledge.

 

1) Should I strip down before use?

2) If yes, how far should I strip down and what issues should I look for?

3) Should I clean off all the factory gloop?

4) If yes, what would you recommend for the cleaning process?

5) When applying fresh lubrication what should I use and where?

6) Any other pointers appreciated

 

I am a WE M4 newbie but very pleased to be learning :D

So how long does airsoft buddy take to ship/deliver? I ordered some parts from him last week and I'd like an estimate...

 

Hi Wraith,

Once I paid for my last order with AB, I had it in less than one week on the eastcoast. Dont know if this helps, your mileage may vary.

 

Kai,

I really dont think pressure is the reason for your "bb rolling out the barrel" issue. I just mentioned that back pressure is a genuine issue with using a tighter O-ring (pressurizes the cylinder on the return when it shouldnt be).

 

I suppose it could be, but more likely your issue is the hopup not reaching down far enough to ultimately stop the bb.

 

This isnt a plastic AEG loading nozzle that only moves back and forth a 1/4"....like the Escort system, its a heavy brass bolt/bolt carrier/loading nozzle winding up from 6" away and slamming the bb next bb in the mag, forward into the breech.

 

Ever play pool/billiards? :P

 

Just shim your hop rubber, or turn the hopup higher until the bb's stop rolling out. You'll figure it out.

Well, I tried putting tape on part 117, and it did stop the bb, but also slowed the rate of fire down and sometimes interfered with feeding. I took it out after a while and for some reason, bb's dont rolle out anymore. Weird. I also found that the little brass ring I lost was actually just stuck up in the outer barrel, and linked up naturally when I put them together.

 

Even though it isnt rolling out right now, I still want a deeper reaching hop up rubber as I can clearly see that these new ones are much shorter than the old. Im hoping it isnt just silicon oil holding bb's in the barrel, but I put about a mag and a half through it, no rolling, even when I swing about the gun up and down. William is looking to see if there is in fact a difference between hop up rubbers as I can see. Ill just order a new one from him to be safe, maybe a new 117 too. We will see.
