WE Gas Blow Back M4A1 Carbine


Recommended Posts

I actually have a PDW but since the trigger box is the same between the two i thought i'd ask here. Is it possible to lighten the trigger pull? I've heard that this is a "realistic" pull for an m4 but for me after years of AEGs and a KJ m4 it just seems too heavy for me and it's making my double taps feel wierd :-S

 

Cheers

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

My friend (Krydel on here) bought a WE SCAR about a month ago, was out of stock in the UK so was ordered from Taiwan. It still came with a gen 1 mag, which obviously almost immediately began to leak and he's in the process of selling. I took it apart, it really is an awful design.

Hi guys...

 

I've taken the plunge and bought an OB XM177e2... Love it, great fun etc...

 

Quick fix needed please, I'm aware it's a known issue (by searching on the various forums), but nowhere seems to explain the actual fix.

 

I'm using the 20 round mags, and one of them doesn't want to sit properly. The magazine feed lips don't clear the feed ramp (correct term?), so the mag won't insert fully without a good smack (which seems to be the generally considered 'fix'). Whilst I'm not afraid to put a reasonable amount of force behind seating a mag, with the bolt locked back, I can see it's a good 1mm+ of overlap to overcome with brute force, and I'd rather not ruin the feed ramp, or excessively smash the mag lips (which are already showing wear from the couple of times I've given it a whack).

 

There is no obvious difference between this one mag with an issue, and any of my others which seat fine - So there's nowhere obvious I need to file down. Can anyone suggest a fix, or is this just one of those things, and I have a defective magazine?

 

Should I take a file to the front of the lips, or will that cause further issues?

 

Any help very gratefully received :) Thanks in advance.

I saw this issue a couple of pages back, and it does indeed appear to be (very slightly) raised at the back. By about 1mm (so enough to tilt the feed lips out)

 

Stripped the mag down and reseated the top section, but it refuses to sit flush. Tightening the screw further is risking stripping the threads... The metal used for the screw itself is very soft!

 

Unfortunately unable to take a pic right now, but I think I've found the issue... Just not a way to fix it yet :P.

 

On another note. Do these 20 round mags take 20, or 30 rounds?? The manual states 30, but I've read that trying to force more bbs in than you should, will almost certainly break it, so I'm loath to find out just by trying to load 30 in.

 

Appreciate the help though... Ironically I went gas, as taking a gearbox apart just never goes well for me! :D

Give it a little tap with a rubberized tool, like the grip of a screwdriver and it should pop down, tightening the screws does not help, you need to tell that mag lip where it belongs with some authority !

 

:)

 

Just make sure you tap the flat back end so you dont break the actual lips.

In answer to my own "how many rounds does a 20 round mag hold" question, I've confirmed the answer as 20, despite what the WE manual says.

 

Luckily I managed to find this out before running out of patience, and breaking something :P

Just ordered a new WE HK416 pre-upgraded from RA-TECH.

Would anyone recommend any further upgrades over the following that come fitted:

 

  • WE 4168 Open Bolt GBB Rifle
  • RA Precision inner barrel 6.01
  • RA steel CNC hammer
  • RA steel CNC sear
  • RA steel CNC trigger
  • RA TECH WE Valve Locker
  • RA TECH WE firing pin base
  • RA Hop Rubber
  • RA TECH Open Bolt NPAS

I know this is the M4 thread but internally it's essentially the same!

I just picked up a real steel AR15a2 upper receiver tonight. Over the next couple weeks i plan to modify it to work with my WE m16a3. Doesnt look like much work is required, just a few notches cut and a little grinding.

 

Ive never understood why its impossible to get an M16a2 when practically everybody makes an A1 upper.

 

No love for my generation i guess. But Hopefully this turns out well.

I had no idea a real steel upper could be adapted to work with airsoft components. That's certainly not something the laws of most counties would ever allow.  :no:

Yea, show us some pics if you get the gun up. M16 is a neat rifle.

 Today I finally broke down the RS upper receiver. I had gotten a Bushmaster DCM competition upper for relatively cheap. Only problem was it had a heavy national match barrel with a DCM free-float tube installed, from the factory and the barrel nut was on tight as hell. I had the appropriate armorer's wrench for the tube but I had to borrow a receiver vice block from the police department (We're pals, I make their body armor carriers).

 

Since it was a bushmaster upper though, I had to use a propane torch and an 18 inch breaker bar to get the damn barrel nut off. took the better part of 2 hours or so. So now that the barrel is off I can start doing the modifications necessary to the upper receiver.

OK, so, today I was able to do the modifications to the upper receiver. It fits the WE perfectly now, And the barrel indexes up perfectly as well.

 

On,ly issue is that the chamber doesnt have an index pin like you would find on a real AR15. So, since theres no inner lip on a real upper receiver to set the headspace, I have to add an index pin myself. Im thinking to just use a grub screw.

 

But heres what it looks like assembled, just the chamber can wobble around so its not fireable yet.

Problem isnt modifying rs parts to fit airsoft guns, the problem would be modifying airsoft parts to fit RS. If i can legally buy an AR15 upper, theres no reason I cant legally chop it up and stick it on a toy gun. However, If I want to take a toy gun receiver and stick it on a real AR15, and it works, thats an issue.

 

Of course, a WE receiver would explode if you attempted to fire a 223 round from it.

Whow, it looks nice! Do you have a Prime lower receiver on it? Is the outer barrel a stock one, or a steel version (it has a grey color)?

 

Another thing, does anyone have a complete list of RS parts that will fit WE M4/M16? I know quite many external parts fit. I was mainly thinking about hammer, fire selector and trigger.

everything on that is stock aside from the Bushmaster upper receiver. However its an older WE closed bolt, not a newer body.

 

I know that almost all RS furniture is compatible with the WE, but Im unsure about the buffer tube itself.  I also dont think you will be able to use any RS internals, as WE's have their own trigger pack that drops in.

Brigg - have you had a look at Turok's "real steel" WE M4 build over on GGi? He even manages to use a real lower receiver (lots of mods, but it fits), and he's done some great pictorial guides on how to do the mods.

 

The following real-steel parts, from my own experience, will fit:

 

Buffer tube and nut

Stock plate

Buffer

Forward assist assembly

Ejection port cover assembly (slight mod to receiver so ball detent on ejection port cover clips into place securely)

Fire selector (with modifications)

Charging handle (with modifications)

Z-M Accuwedge (reduces slop between upper and lower receivers, but needs serious butchery)

To be honest, Having installed the open bolt kit into it today, I wouldnt bother putting any other RS parts onto it. I wanted an A2 upper because WE doesnt make one. I dont see any reason to use any RS parts beyond that unless they are somehow going to improve performance.

 

Also there is absolutely no space or slop between the upper and lower receiver, it fits like a glove.

I tend to use real-steel parts where I can because they're either better quality, better designed (or manufactured) or in some case the same price as the WE parts (so why not go real-steel in that case? A prime example is the awful forward assist that WE use. I can pick up a real deal DPMS one for the same price, and it doesnt have a nasty looking screw in the middle of it. The cheap and nasty WE stock tube is another example as well, it weighs three times what a real steel Milspec stock tube weighs. And don't get me started on the dire quality of the WE charging handles...

 

I've got 4 uppers and two lowers, some have some slop in them and some don't (well, none of them do now I've chopped up a couple of Accu-Wedges lol)
