AGM Gas-Blowback M4

[renegadecow]

This should show if the forward assist button is functional:

Its there (parts number 63 to 67) or at least thats what your manual says. If you remove your bolt carrier and peer inside from behind, you should be seeing the tip of #54 poking out when you push the button.

Any idea on mag compatibility?

 

Edit: I just looked at the pics and from the looks of it, at first glance it sure did look WA'ish. So Assuming the Mags are compatible would be a good thing for current WA owners. Looks good enough to plink around with before something goes wrong.

GHK mags fit, so I assume WA and all others for WA fit as well.

[pforcerecon]

Well that's a relief to hear. Also, I just checked ebaybanned, and they have it up, with both the railed and non railed versions. Hahah, and only at a $2 difference.

The other thing I was thinking, and I hate to say this, is that it looks like the WE M4 is going to become a bit of a white elephant.

Sure, it was a brave attempt and you've gotta applaud them for actually having a go and designing something for themselves.

Having said that, with all these clones of the WA gun coming out, I think most WE owners are probably heading down a dead-end street.

Sorry.

The US Army is trialing the WE GBB with its stock steel internals. Doubt they'd look at a $126 WA clone that (currently at least) does not suppport CO2 power.

 

I think that the WE is the leader in the functional and quality area- i.e. I think it's already positioned as the 'Systema' of the GBB rifle pack. I've used both rifles and the WE is streets ahead of the WA. It's steel internals and CO2 power is awsome and it recoils like real 0.22 firearm and pretty close to a real steel Canadian C8.

 

However unlike Systema, WE has priced their M4 at a much more sensible price. Systema was never worth the money but for me it was more that whenever anyone fired a Systema it reminded me of my grandmothers sewing machine.

.22 yes, 5.56 NATO no, I doubt it very seriously as even externally powered HPA GBBs don't come close. I also thought that the WA more closely mimicked the RS internal configuration, and the WE only sort of did.

 

It may be possible you're right and the army is testing them, but I highly doubt it is for the reasons you're stating (recoil and realism), I bet it is more of the fact that it has a metal body and is cheap compared to the plastic bodied WA and it's more expensive metal bodied compatriots. This AGM may change the whole ball game though, if it met the deadline for contract proposals, which I see WE, G&P, Ino,and WA doing but not AGM.

The guys are right,the tube is central to the AR GBB system,as the bolt that being blown back, cocking the hammer on its way rearward,readied for subsequent shot,the bolt needs to be returned(by the energy stored in the buffer te compressed buffer tube string) to chamber a round and getting ready to begin a new cycle. While it's possible to do away with the buffer tube but it needs to adopt a new design called short-stroke piston like the one found on AKs,SCARs and 416,where folding stock is common.

You obviously have no Idea what your talking about.

 

The piston system has nothing to do with the travel of the bolt. For example The HK416 uses a Short stroke piston and it still needs its buffer tube.

 

AK receivers are longer while the bolt is much shorter, so the recoil spring can be accommodated inside the main part of the receiver.

 

The buffer tube merely holds the recoil spring, as there is no where else to put it. And yes the carrier goes into the buffer, many people call the buffer the RECEIVER EXTENSION.

Haha, wow. the we rifle is no were near the WA as in realism and the kick doesnt even compare to a western arms with a 150% recoil spring. You just havent played with a WA that is fully upgraded with RA-TECH and G&P parts yet. Youll know the difference when you have done that.

[snorkelman]

add to that:

 

the CO2 version is only just going on sale bit premature to be claiming it's awesome

 

the internals on the stock guns look more like a mixture of brass, steel and I think a few pot metal parts?, I dont know if they have an all steel set of internals available as an option but Ive certainly not seen any photos of one

 

the only US army testing being done that I know of is the use by some US army personel who also happen to be airsofters. That dont = US army testing to me - if I bought one tomorrow I dont think anyone would be claiming my employer was testing them as a training weapon.

The Canadian C8 has a barely discernable re-coil- much lower than a normal Colt M4. The WE recoil is similar to the Canadian C8.

 

As for the US Army testing the WE- not a case of 'possible' but fact. Check out http://www.weairsoft.com/video_view.php?video_id=5

 

I think WE are here to stay at the high end and professional training market. Systema may find itself in a difficult place- I wouldn't be surprised if Systema released its pwn GBB M4. If it did I think it would be WE based!

Doesn't anyone check their facts? Seriously just research before you post. http://www.weairsoft.com/video_view.php?video_id=5

 

Also the US Rangers have been using Airsoft weapons for CQB/MOUT training for years. They even appeared using airsoft weapons on the History channel

[snorkelman]

if that video is the one your going to cite as proof its being tested as a training weapon by the US army then you're up a gum tree

 

Cos its the one of the US army airsofters on a US army base putting it thru its paces under the auspices of their garrison sponsored airsoft team - not the US army testing the gun as a training weapon Its even been crudely edited around 1.50 or so to skip out the part where he specifies exactly what the event is

 

"we train for three weeks then we get a break and do this event" "we're sponsored by" etc

 

in other words it some sort of PR exercise laid on by US army at that base every few weeks - during which the garrison sponsored team of US army personel both host the event and take part

 

If safeway sponsored an airsoft team of safeway employees and temporarily handed over a Safeway warehouse to host the event in would that = "safeway are evaluating the WE as a training weapon"

 

Course it wouldnt.

You're pretty good at making things up dude. Why don't you come up with an explanation of why men did not land on the moon.

 

Writing dribble is never a good substitute for research. You should free up your unconvincing imagination and trying doing a bit of research- it won't harm you but hopefully it'll spare us the dribble.

 

[snorkelman]

the only dribble here is your pish

 

steel internals when theres a big fooking brass cylinder visible thru the ejection port for all to see. shine on

 

try watching the video objectively if you cant see the edit that lops off a bg chunk of his sentence at 1.55 then your half blind

 

If you cant note the context of whats being discussed at that stage of the video your clueless frankly Im not going to waste my time providing you with a word for word transcript open your lug holes and have a good listen at whats actually being said in it.

I have a question in terms of the GBB m4s: With such high FPS out the box, is there a way to lower the FPS to a consistent 400 fps? I've tried searching the WA and WE topics, but it's a bit much to look through.

They are quoting that high with GG/Propane. If you use Duster it should be closer to 370....I'll let you know in a few days once mine gets here.

Duster? I am not familiar with this type of power. I should find out what propane shoots as well in a week.

ahhh, ok. Got it.

From personal experience I can reveal that, in a similar manner, the US army is also trialing Jack Daniel's, The XBox 360, Harley Davidson motorcycles a variety of porn magazines and Marijuana.

 

*EDIT*

On a more constructive (and less imaginative) note, I'd suggest somebody with one of these guns in the UK takes a look at the magazine and tries replacing the valve spring in the mag with a stronger one.

If we can find a suitable spring, off the shelf, that reduces the power to about 1J then I imagine we'll all be falling over ourselves to buy them for our mags.

Off course i'm wrong about the inner working of rifles,especially the short stroke piston not needing a recoil spring,the ones not having buffer tubes actually just designed to have it somewhere else in the receiver,thanks for the knowledge n sorry to mis-inform anyone who doesn't know better. cheers.

r

[snorkelman]

the LR300 is the most obvious example of an AR without buffer tube

 

theres a hollow gas key bolted onto the bolt carrier which extends for full length of the gas tube (it surrounds the gas tube) surrounding that hollow gas key tube in turn is the recoil spring (running length of the tube). At front of this assembly is a little clip that fits on front of the gas key tube, just ahead of the recoil spring

 

when rifle fires gas goes down the gas tube as normal, bolt carrier and the hollow gas key tube attached to it recoil

 

the little clip fitted into the notch at front of the hollow gas key goes rearwards with it and, as its larger than diameter of the recoil spring, the recoil spring surrounding the hollow gas key tube gets pulled into compression at same time.

 

when bolt carrier reaches end of its travel the compressed spring expands again - exerting pressure on the clip at front of the gas key tube (as thats sitting directly in front of the compressed spring) effectively pulling the bolt carrier back into battery from in front of it. As opposed to normal AR - where recoil spring sits behind the bolt-carrier and pushes the bolt carrier back into battery, as the spring expands back to its uncompressed length from the rear

 

End result no need for a buffer tube on LR300. The bolt carrier is shortened at the rear - as it no longer recoils into the buffer tube, just whacks against a small flat buffer fixed at rear of the buffertube-less receiver.

 

To be honest other than the fact its hollow and telescopes around the gas tube, the setup does resemble a very long AK style gas piston with a recoil spring surrounding it, so I can see where some confusion would creep in

Since the WA M4 uses a Magna system, won't the fps reducers work as how they were implemented in Magna handguns? Its just a plastic diaphragm with a pinhole to limit gas flow. A weaker hammer spring might also work.

Uhuh.

 

Only reason I picked the mag valve is because it's usually a standard spring rather than anything fancier.

My point, really, is just that if these guns are shooting hot for most UK sites we probably need to find a sensible, reliable way of reducing the pressure a bit.
