WE Gas Blow Back M4A1 Carbine

[gripper]

I tend to get it working how I want it, and then leave it the hell alone...

 

This one works great, but it's too hot for full-auto at my local site, and thus I need the RA-Tech NPAS.

 

Ben.

 

A GBB Rifle is not an AEG that you can "leave the hell alone". GBB rifles require regular maintenance, much like a real steel rifle. And parts will break with usage - just like a real steel rifle. Luckily, as with a real steel rifle, your GBB is designed for easy field maintenance.

 

So you'll have to get used to cracking open that thing sooner or later, so you can lubricate and/or clean off the dust/dirt/etc. But don't be afraid, it's not an AEG with a gearbox, screws, and hex bolts. This GBB rifle is a breeze to take apart.

 

To remove your bolt and look at the nozzle, make sure the mag is out and your hammer is de-cocked (just put the selector in "semi" and pull the trigger). Then push out the rear pin above the selector switch with your finger, pin, small screwdriver, or a pencil. Just push it in, all the way through until it clicks on the other side of the rifle. I will not fall out.

 

Then grab the top of your upper receiver (where the rail is that you mount your optics/carrying handle) and pull up. It'll make the barrel pivot down, folding the rifle into an "L" shape, with the barrel pointing straight down. Don't be scared, the barrel/upper receiver won't fall off as its held by another pin in front of the mag well.

 

Then grab the charging handle (a/k/a "cocking" handle) from the hanging receiver and pull it back. Don't worry if your charging handle falls out.

 

That silver metal thingy right under the charging handle "T" is your bolt. Simply grab it and pull it the rest of the way out, you'll have to angle it down a little. but it should pull out easily. Once you have your bolt out, just look at the nozzle in the front. If you have a version 1, you'll see a two o-rings the same size. A version 2 has the rear o-ring bigger - it looks stepped. Also, in this slightly disassembled state you can now clean the inner receiver, trigger pack and the bolt of dirt, spray in some lube, clean your barrel (you can look through it now), check your hop-up, etc.

 

To reassemble, just reverse the steps above. If your charging handle fell out, don't jam it back in straight... angle it down a little and push it in until the charging handle slips into its groove. Also, with the charging handle still pulled out, you'll have to slide the bolt back in under it. Then the charging handle and bolt will both move together until they fall back into place. Then pull the barrel up back up until it doesn't look like an "L" anymore, and looks more like an M16, and push the pin back into place. If it doesn't lock, make sure you have the selector in "Semi" and the hammer is de-cocked.

 

Afterwards, pat yourself on the back. You just took apart your first M16. And if perchance you are given a real M16 in the future (Zombie Apocalypse, etc).... you now know how to break it apart too.

 

You might also want to eventually pick up an armorers wrench and learn to take your barrel out. You'll eventually have to do this when you need to replace the hop up rubber, which will wear out faster than an AEG's. But, once again, it's a 5 minute job compared to working on AEG.

Hey this will help: http://wem4guide.wikidot.com/

 

Has everyone forgot about it already? It's well useful.

[renegadecow]

I would even go as far as saying that its disassembly is a function rather than a feature. Don't be afraid of screws and small bits popping out and disappearing; it's not happening. To further enforce how easy it is, check out this 11-year-old going at it:

*disregard the further disassembly of the bcg as hers is real

alright, i dont really have time to read all 300+ pages of this thread but um considering getting a WE M4. i know it has its flaws but are these fixable? either with replacement/RS parts or by making my own? (i have access to full shop/CAD equipment and can use it). my other main concern was accuracy, has anyone solved the hop-up problems?

thanks in advance

These guns are sick. My only complaint is the availability of parts. The stores that do stock them have horrible service so it's a crapshoot of when they will arrive, if ever. There are a few things that are recommended to change like the nozzle, getting a tightbore, the new hop up. I recommend it. There is a small group in Calgary, three of us that I know of, that have them.

AirsoftBuddy shipped my two recent orders very quickly. OTOH they haven't responded to my emails and some people have old issued that were never resolved.

Yeah, I've noticed that you've managed to get two orders shipped to you from them in the last month, and in just over that time I've had a confirmation email, and an update to "processing" email. both within a week of the order being place, and sod all else since. They've just been sent a politely worded threat of PayPal dispute. If PayPal do nothing, I'll have a chat with my bank about it.

[kojak]

Maybe they have another email address that actually gets read/answered?

[AKRay]

If they do, it's not on their website, 'cause that one's the same as the one the order info gets emailed from

[RayL]

Just open a Paypal dispute, give it 2-3 days then escalate to a claim if AB doesn't respond. I waited for my order for over 2 weeks with zero communication. Luckily I was refunded my full amount through Paypal, and ordered my parts from another overseas retailer.

 

Stay away from Airsoft Buddy, they only offer one shipping method (EMS 3-4 day delivery) which isn't cheap, and they won't ship your items until they feel like it.

[mike1964]

Well im quite desperat now after dealing with AirsoftBuddy.

And not reciving my order despite having payed for it.

 

They also do not answer my mails.

So my last resort is to try here!

 

I orderet a WE. Co2 GBB M4A1 around 11 juli and a RIS & Magpull grip from AirsoftBuddy/

William.

The RIS was out of stock, but no info here on the homapage and before i made the order and send the money.

So i had to wait until 18 august before the packet got shipped off.

Well ok...

I then made an agrement with William personaly! that he must send the packet with FedEx and NOT! HongKong post or any otheres, cause they will after arival to my country (Denmark) hand it over to locak postal company after custum inspection.

Post Denmark as it is called here, has a policy that they do not handle ANYTHING weapon relatet, thet also include airsoft weapons and assesorys.

When they get it after cleared with custums they see what is in the packet, and when weapon relatet, they right away ship it back to the sender.

So i specificaly made an agrement with William that he shuld send with Fedex and he charged me for this SHIPMENT WITH FEDEX! 160 $

 

By the 23 august i had still not heard anything and recived anything, so i contacted them and first THEN i godt a tracking number.

There i saw this:

 

Posting DatePosting TimeDrop-off Point18-Aug-200917:01Kwong Wa Street Post Office

He had send it with HongKong post and they hand it over to Post Denmark when it arives just as i told them, and they refuse to handle tha packet when they find out what is in it, and ship it right back.

 

I didn't pay 160 $ for THAT!!!

 

I wrote William and told him, and he said that when they got the packet return, they would ship it off rigth this time with FedEx.

 

He recived the packet the 27 august and wrote me that he would send it to me again this time with FedEx on the 31 August.

 

Since then i heard NOTHING from him, i recived nothing! and i have now written more than 5 mails, but get NO reply!!

ONE full month today since last reply and promise of shipment.

 

I must ask WHY!! dosen't he answer my mails?

 

Why has i not recived my order that i have payed 630$ for now close to 4 month ago???

 

The delay when item was out of stock, i can accept and thats what happens! (he could have pointet this out when i send the order!! but well ok...)

That he make a mistake and despite an agrement and something i stated severel of times! and that he agreed to and that I PAYED FOR! do NOT send it with FedEx.

Well rather anoying and stupid! butt i can live with this and a slight delay AGAIN! and forgive this... (as long as i don't have to pay extra shipment for HIS! mistake!!)

But that i am being promised the packet at a specific date and then hear NOTHING (not to mention recive nothain!!) for a whole month! despite several of mails.

That i have a werry hard time to accept and understand!

This ###### me off.

That is not a way to conduct buisniss and to treat custumors, specialy not after the long wait i have already had! and the *fruitcage*up with shipment!

 

WHY don't i get my order???

Why dont i get a reply!???

It makes me worry and makes me sligt paranoid and thinking if im being swindlet out of 630$???

Well i don't like to think so??

I hope for some explanation and that it is some mistake?

 

Going public here is my last option since William/AirsoftBuddy do not reply any mails.

[alston251]

You guys know AB and AFC is the same thing. They operate on the same shop or something. The people in the shop deals with the orders. As for William i'm not sure what he really does. But i swear i've seen him the the shop once or twice. I can recognize his M4 And any new product from AB is presented in the AFC shop few days ago.

 

I think this is because no one actually buys from their site. Not that i think you actually though.

[alston251]

From what i know they are the ones who deals with the internet orders too.

[Cephas]

Has anyone heard anything from WETTI recently? What happened to the PDW, HK 416, and m14?? Is it just me or has it become increasingly difficult to allocate spare parts, such as CO2 conversion parts.

[Reppyboyo]

Its always been hard to find spare parts.

Even the 'official we distributor' for the UK is having trouble getting parts.

[kojak]

Same thing with the "official US distributor", Evike.

I emailed Wetti last night about the 416, apparently it'll be out in 2-3 weeks, didn't ask about the KAC PDW, or the M14

[Kowalsky]

sorry to change the topic a bit, but just went through all the pages (for 5th or 6th time) and i think i didn't read anything about it (maybe i missed it, wich i doubt...). Is there any way to reduce the amount of gas released from the mag in every shot? i'm not talking about a NPAS or a TSC-rod, but something like a "low-flow mag valve", to reduce the FPS (to a constant value, no need to be adjustable) while increasing gas "durability".

 

I've found myself that i get 60-70ish shots with my CO2 mags (i get about 90-120 with GG), and i'd like to increase that amount of shots slightly (if possible). Is there any way? or do i have to carry a lot of CO2 powerlets?

 

Thanks for the answer

[HSOJGNILRAD]

Just installed A Rock River Arms Charging handle and forward assist......they work with no mods at all. Also I have the RA-Tech NPAS coming in the mail for both the M4 and SCAR. I will let everyone know the results when I get them installed.

[Bastel]

Can you say me, which part has the better quality? effect?

[CommieHunter]

Cheers that's the exact one. Other than i bought it from guns and guys.

 

Edit: I know what's wrong... The chinese replica doesn't have the bit of rail where it showed you to drill through in the pic. They just machined the whole chunk out. So you can fit it in easier...

Damn. What can i do now? Think all i can do is loc tite it down..

 

It's the second failed rail! My replica DD Mk18 rail rattles like crazy and now this doesn't keep the barrel nut in...

WE's compatibility issues are really giving me a tough time.

 

 

Part of the problem is the Chinese rails you're using. If you get better quality rails (MadBull, SOCOM Gear) you won't have these issues. It's not a WE M4 compatibility issue, either. The WE M4 uses the same threading as the real AR15 does. You just need to torque the nuts down tight enough (and do use blue loctite).

 

I've got the SOCOM Gear Lite 9 rail on my WE M4, and it's more solid than the upper and lower receiver are.

If he wants I have the 9" socom Gear rail I would trade him for his. It fits like a glove.

You could try shortening the valve knocker. I don't really know how much material reduced will relate to consumption gain, but for sure your output and recoil will be reduced as well. I'd work on a spare knocker if I were you, shortening it bit-by-bit until there's a slight felt loss in recoil and/or fps and check to see how much gain it has in consumption.

 

Theoretically though there's 2 points on the knocker that you can shorten: the actual strike face or the part that engages with part #66. Shortening the first will mean a lowering of both fps and recoil while the second may just lower your recoil and still retain your output.

 

edit:

forgot to add that you could also restrict the magazine by putting something under the rubber seal thereby limiting gas flow. Doing this will probably lower everything though but at least it's rectifiable.

I got my second order from ASB today (my first order is back in Kowloon, hopefully it comes back to California soon .

 

Pardon the cameraphone:

 

 

The chormed (who knows, maybe it's a new high-tech coating we don't even know about) barrel is nothing new, but did come with the latest hopup. The nub looks like it's angled to one side and it lacks the 2-bump design of the green rubber. Also, it's a miracle the barrel wasn't bent in transit since it arrived in a plastic mailing bag with only bubble wrap to protect it. My old 262mm chrome barrel is going up for sale.

 

Part #59 is the whole reason I took my gun apart, the previous owner had a homemade replacement installed (which eventually also broke) that was supposed to be an upgrade. $150 later this is what I'm most excited to see, a stock $1.50 part! Are there tougher ones out there, or a way to keep it from snapping?

 

EDIT: LOL I just read the sig in the post above mine--I have a bad habit of ignoring sigs what can I say? PM inbound....

 

The bolt stop plates showed up today from Airsoft123--it took three weeks but hey, free shipping! I only got six for some dumb reason so I'll mark the mags they go in and keep track of any failures to lockback. I ordered the "new" steel bolt catch too, but since I don't have it yet I can do a little objective testing before and after.

 

 

I haven't dismantled any of my mags far enough to see where "CO2 Valve Part 2" goes yet, but I will tonight.

 

 

Here we have "Steel Made Part #61 and #66", which seem to indeed be machined out of something. Not sure if they will improve function, but steel is good, right?
