@3vi1-D4n

I know nothing of it's inner workings. If you have spare moment, could you take a pic or even describe it a little more specific what to do to it?

ok, thanks..

 

its not a problem at all cause its not interfering the function of the rifle I was just wondering that after 200 rounds the material will degrade so fast.. but the material is very thin on that place in deed..

disassembling

the thread in front of the.. front sight. with the short inner barrel installed is that the place for the flash hider.

 

the disassembled front sight.. 2 pins and a screw holding it in place..

 

G&P barrel nut and delta ring installed

 

outer barrel disassembling

 

 

hop up / inner barrel

as previous stated, the inner barrel is whobbling a bit due to missing spacers.. so I put some tape around the inner barrel..

 

..and it works

 

 

the hop up hole at the back of the inner barrel

 

the whole hop up unit..

 

.. and closer..

 

.. and disassembled.. as you can see on the right side, the hop up is pressed down by a ball bearing^^

bolt carrier

 

 

 

 

 

 

bolt stop function

the bolt stop itself

 

here is the bolt stop function deactivated by the mag..

 

here, its activated

 

now, the bolt will stop behind if the mag is empty

 

now, it will not stop

I've disassembled the gun and made some detail photos I'd like to share with you. The photos are (very) big and I hope there are some new details for you..

 

 

Firstly, I encountered "some" wear out within the mag well as you can see on 2 photos, while I've only shot about .. 200 - 300 rounds..

 

Can anybody check his rifle if there is wear out, too? Lupus, Jin15... etc?

AirsoftBuddy, maybe you can send this to WE,.. ?

 

It seems, that the inserted mag is "pressing" against the mag well and from the other side the mag release spring that is "rubbing" against it.. especially when releasing the mag you are manually "rubbing" that spring against it..

 

 

overview

the WE sign on the front sight.. one of the few markings on the WE M4

 

the spring & buffer wich can be found in the buffer tube ( uh.. where else? )

 

markings on the top rail of the upper receiver

 

the upper receiver, back.. seems to be very thick and stable

 

thick bolt carrier.. seems to be very good material

 

the bolt carrier half inserted

 

 

function

here is the hammer..

 

.. and thats how it works.. the hammer is .. hammering against this pin..

 

.. and on the other side, the pins releases the gas from the mag..

here you can already see the wear out I've stated above :/

 

 

here again, the wear out marked^^

Also, I think this may have been answered but is the flash hider 14mm+ meaning I can pop on any G&P compatible flash hider?

yep, I have my old phantom flash hider on it that was on my old G&P M4

 

 

However, he did say that when we order extra magazines from him that he would include the WE produced steel bolt catch for free for those who have bought the pre-steel-bolt-catch version.

great!

"small" update..

 

I've glued the forward assist know with "power glue" .. hope it will stay in place..

 

 

 

The G&P free floating RAS fits perfectly as you can see here

 

 

[WE Gas Blow Back M4A1 Carbine]

my M4 just arrived

 

the forward assist knob and the spring were already "not in the right place" when I opened the box.. so I'll try to glue the knob back in place.. but I#m not sure if glue will hold the knob with such a big spring behind..

 

-> but wow, what a sound..

-> the mag leaked just a few seconds before it stoped..

[WE Gas Blow Back M4A1 Carbine]

ah, ok! sounds like a very small problem.. at first i thought "what? the whole knob came out?!"

 

[WE Gas Blow Back M4A1 Carbine]

ah Lupus78.. can't remember, but is the forw. assist functional?

[WE Gas Blow Back M4A1 Carbine]

According to SAA, WE already ships their new rifles with steel bolt stops.

I'd wish, WE would give all who bought an "old" version a free new bolt stop..

How many old versions could be out there already?

[WE Gas Blow Back M4A1 Carbine]

would it be possible to adapt a RS bolt stop to fit the WE M4?

it looks like that you just have to remove a bit?

[WE Gas Blow Back M4A1 Carbine]

maybe u should read the last 20 pages.. if u want to buy it, it could be important to make a decision.

I can't identify the broken part in yehaws last picture.. what is it?!

 

Would be interesting to know which parts can be replaced by original M4 parts.. especially internals.. trigger assembly, fire selector, charging handle, dust cover, ... ( http://www.ftfindustries.com/AR15SmallParts.htm <- for example )

 

 

 

 

/me is still waiting for my own M4.. should be here next week..

[WE Gas Blow Back M4A1 Carbine]

ahh....ahh!

 

yes.. my picture shows RS M4 parts.. I think the charging handle is the same as in/on the WE M4..

[WE Gas Blow Back M4A1 Carbine]

I'm confused .. why do you posted it then..?

[WE Gas Blow Back M4A1 Carbine]

would be interesting to know.. a RS charging handle costs about 20$ too.. in US.. here in GER i found one for 60eur..

[WE Gas Blow Back M4A1 Carbine]

Does a RS- charging handle fit? And.. how the... can it brake?!

 

edit:

it seems so:
