KWA M4 ERG (Electric Recoil Gun)
 

KWA M4 ERG

Frankly, IMO, it just looks like Marui's "recoil shock", maybe a bit stronger. Again with proprietary mags BUT normal AEG mags work, which is nice, but the gun won't stop firing if you don't use the KWA mags.

As far as electric blowback goes, my money is still on RS' magnetic design.

nice improvement!Cuz TM's recoil m4 has a crisp plastic body,the stock is pretty wobbly.
I bet this one is the most skirmishable AEG if ur a regular milsim guy.

It has a metal body....

I would wait for RS... this is just a improved version of Marui's recoil engine.

kwa always come with metal,unlike tm.

But I'd admit some jp companies have made their plastic look/feel more than just some alloy used for toy guns.Unfortuantely tm doent fall into that list.

When was the last time you've seen a recent Japanese gun?

All the most recent AEG's that TM's been making have been Aluminum...

Wait what? :confused:

Do you suspect TM is going to start making their M4 Recoil Engine AEG without metal bodies?

Anyhow on the topic: Looks great, will definatly buy it when it comes out UNLESS, the RS has greater recoil and is more durable & accurate (essentially just better all around), and can take standard Mags as well.

This is just a modified TM Recoil Shock M4 with a fancy name. And just like the TM version, you can use standard mags but the TM requires an adapter. The RS will look much nicer but if it's built like the TOP shell ejecting M4, it won't be able to handle too much power. I'm just guessing from the pictures I've see, but I do hope RS have a solid design for the gearbox.

On the subject of the RS, anybody hear when those are supposed to be out?

As nice as those RS blowback AEGs look, we've yet to even see an actual WORKING model. Until that happens, I'm not holding my breath.

i'm not keeping my hopes up either but RS has A LOT of pressure on them right now, with that design being called the "gasless GBBR" and such. They usually come out with solid guns and all seems to point out that way with their new design.


EDIT : here's another video of the thing with another test fire (and corny slow-mo shots to boot), just skip to 12:30 mins.

the modify recoil kit kicks more than that

Imo, KWA needs to stop toying around and release the civilian version of their LM4 GBBR

Don't blame KWA for the LM4 delay. It's the BATF that's dragging it out. Government: why solve real problems if you can micro-manage airsoft guns. Stu. Pid.

The LM4 delay has nothing to do with the BATF it was there doing in not releasing it, they also were never told that they couldn't bring their gas gun into the USA, they just wanted to hold the rights to an airsoft GAS Gun that was approved by the ATF and permanently stop the importation of WE and WA guns. Furthermore if this wasn't the case they would be shipping legally into canada also but they continue to turn a smug eye to us as a legit market

Where the heck did you hear that? :/

So, am I the only one looking fordward for the arrival of this AEG in Canada ?
Althout I'm no a big fan of "magpulized" AR's, I would buy one of these.

Would wait for Real Sword still... if that ever comes out.

I know, but I've been waiting for their QBU-88 almost three years.. I wouldnt hold my breath for RS AR since we havent even seen a working prototype. In the meantime the KWA ERG seems like a viable option.

Again, something I'm looking forward to picking up and posting thoughts on here.

Heard a rumour it should be out beginning of 2nd trimester

I didn't know we were counting time by pregnancy gestation period nowadays.

And the PTS ERG?

Maker is Yih Kai Enterprises on the gun....is that Ares?

Hey Guys, I won one in a contest, and let me just say WOW. I have yet to game it, but holy balls batman this gun is sweet. The kick back is amazing I'd rate the blowback juuuuuuust a little under that of a GBBR. And as for the proprietary mag thing, meh I have Ares M4 mags that are 8 bucks a pop and no worries there. Like mentioned in countless reviews the only downside is that the rifle won't stop firing when it's empty. I will buy a set of mags specifically for that gun, but that'll be for next spring.

Looks like you're gonna lose that bet.

Anyone own one of these yet? With fairly extensive testing?

I'm curious to how accurate it is. How reliable it is? Is it upgradeable or does it need to be upgraded? How's the hop? What's the recoil like? Anyone know when the cqb version will be here? I'm a fan of the shorter style coming from a mp5.

I'm torn whether to build an rhop'd m4 from the ground up or settle with one these and a sweet recoil engine.

magic box is making parts for the ERG line.

I tried one that was tuned by them and Im ashamed to say that the AEG kicks harder than every single GBBR I've owned. The only problem is the trigger response, its still not as snappy as I would like it to be and the magazine capacity is extremely low, 30/50 rounds is simply not enough for airsoft

Maybe because you to have 150 bb's per magazine. /cheater

Yeah, had my eyes on this after I sold my KWA LM4. TA has them for $500?

Went a different path instead ;)

I will be bringing in a small shipment of CQB length ERGs. Watch the sales thread for details.

Interesting - a quick-change spring gearbox design that actually works.

Looks like I'll have to get one to mess with.
Too bad the mechbox looks like it ONLY accepts standard-ratio gears...

i got one :) wanna buy it lol

I can safely say that this gun is bonertastic

1) Has it been molested?
2) $400?

But seriously. Has anybody upgraded the shit out of this thing yet?
Thinking aloud - I wonder how the buffer spring interacts with the main spring - does it speed up piston return time? Does it add spring force?

well, I lied I had 4, one has been tuned my Magic box and the other 3 are just stock.

other than MB, I dont think anyone has modded these before, their trigger response is horrid tho :/

i brought in a few of these because the Scouts didn't see very well, but turns out I had all but one sold before they even arrived. So I've got 1 left. If you're interested email/PM me. Price will be the same as the Scout model.

Trigger response with MB parts still horrid?
Was the gearset replaced?

Stealth, just get a BOLT. Less proprietary, and REAR WIRED!

While I haven't tried the Bolt yet, here's what I liked about the KWA ERG series.

* Actual quick-change spring system - remove the buffer tube a la real steel and swap springs
* Feeds every single round out of the mag
* Improved balance, weight and feel over any other AR15 AEG on the market
* Magpul-licensed body = authentic trademarks
* Backwards compatible with standard AEG magazines
* Stops firing upon last round (only if used with ERG magazines)
* Relatively cheap ERG magazines compared to PTS PMags
* Configurable 30/60round magazine capacities
* Relatively strong recoil (given what it is)

This system has some serious potential - ditch the recoil feature, up the ROF to 30+, add a computerized AB FET and the platform becomes VERY attractive.

But the recoil is what makes this ERG unique :cool:

I agree with you.
I wonder if the system can do 30rps though. Will have to screw with it over the holidays/January.

I'm curious to see if this is actually possible. I'm sure playing with battery, and motor you can get a fairly high RPM for this. I think the limiting factor will be the Recoil function of this, but eliminating the recoil will just defeat the purpose of this gun.... if that was the case, you might as well be starting off with a G&P Magpul M4.

A G&P Magpul M4 does not even begin to compare to the KWA RM4...

The recoil isn't the only thing the ERG has going for it (see post 36)

I don't understand the point to ramping up a guns RoF to 30. Can someone explain to me what the actual benefit is? (No offense or sarcasm meant, I'm curious).

From my perspective, 15rps gets the job done just fine, you're still going to hit your target with weight of fire. Heck, semi-auto is, more often than not, fine. I just don't see the point in emptying your mag faster and increasing wear & tear. Am I missing something else?

Faster rof = faster trigger response in semi. Fastest you can get practically is a 10:1 dsg on 11.1 battery. Can be stupid rof but 5.xx turns of motor is one shot.

Anyone know which magpul rail sections would fit on the hand guard?

These? Looking to mount a laser.
http://store.magpul.com/product/MAG406/103

Yes, that will fit: There are several GTA retailers that carry full sets of different lengths of MOE rails for hand guards in black and DE for very cheap. I got a set of each for $10-15 each (can't remember exactly).

Thanks Zack

I've got a Bolt, it's pretty awesome. Haven't chrono'd yet but she gotta be pretty close to 420fps and around 20rps on an 11.1. Very tight grouping and strong recoil, fells like most gbbr's. No quick change spring but fully upgradeable/downgradeable. All of my mags feed without issue although a couple are a pretty tight fit. Only negative is the ejection port cover is shit, I'll replace it at some point.

I can't say enough good things about this platform.
Even the hop-up unit is great - holds adjustments and has very positive click-adjustments.

KWA has unveiled the next generation of ERGs will have rear-wiring, similar to the Marui Recoil SOPMOD series. KWA-only trades though.

Just wondering has anyone done any upgrades to the RM4?

I have, so has stealth, not much you can do though, barrel, hop up, motor, thats about it

Ain't nobody got time for dat. I made my own

http://i1349.photobucket.com/albums/...psf09d24fb.jpg

I love KWA guns, huge fan have a beast of a sr10 myself, but can the rof be increased at all? 15 rps is low. Im torn between buying the ERG or waiting for the Tippmann M4 coming out in mid summer. Less moving parts and things to break.

Rm4 is an amazing gun!

GBBR that looks great did you ditch the recoil engine in the buffer tube??

Anyone know what upper receiver threads it use?

Standard AEG for rails. Confirmed.

Electronic recoil Gun is a superior performance and unbeatable reliable gun set KWA. It has the fire power airsoft enthusiast for that has an intense airsoft operation that has an outstanding value.
Features:
It consist features of a full alloy metal upper receiver.
Full metal alloy lower receiver.
Polymer hand-guard, grip and magazine.
Semi/Full automatic.

Hi, I know i'm reviving this but I thought this could be the good place to post this.
I wonder how much FPS people get when they change their springs.
I recently tried to tweak the fps of my pts ERG and I tested a couple of spare springs. One thing that I noticed is that with a light springs (m95) I was getting FPS close to what I expected (a bit more than 300 fps with a cqb barrel). However, the recoil was also pretty less present. When I tried to get the FPS up I noticed that the springs with higher rating (m120 m130) were producing recoil but was getting a lot lower FPS than usual. I'm getting a about 350 fps right now with a 130 spring wich I was usually getting about 420 fps. I just wonder who else tried to change their springs and how much FPS they get. I know spring rating can change but it could give us an idea of what spring to use for 350/400/450 fps.

The ERG's use a Linear spring, while most springs available for sale are non-Linear.(longer springs with closely spaced coils at one end.) If you put a non-linear spring in the ERG it will decrease the felt recoil drastically.

I bought a couple CQB ERGs that were shooting 370fps, I installed an Orga 6.23 widebore inner barrel and it brought my fps down to 348 making it perfect for indoor.

I have also ordered the proper Linear spring right from KWA before, fantastic customer servive and helped me get exactly what I needed.

Thanks, Considering I have only non-linear springs right now this could be an explaination.

I used a m190 in my scout and that got it shooting right around 410fps
