Looks like it belongs to a game like Grand Theft Auto

Your comment made me forget what the AUG actually looks like, I had to look it up because that ACR replaced it in my brain

Stop that

Don't make me think about that.

Thanks for clarifying

Not to be confused with the bushmaster or Remington ACR.

I had always wondered. Thanks

Same. I want it to be reliable so bad. It's such a sexy gun otherwise

@@LDSG_A_Team well it’s a prototype, a production rifle probably would be much more reliable

Every gun has malfunctions at this point of development

But instead you melted an AUG, cooled it back down, and got this thing.

I bought AUG and it was still in a box in hot car. This is what came out.

uhhh no it doesn’t. sorry.

Dude. Yes it does. This is the epitome of melted dog shit

Yes I think you're right that's pretty similar to what I was thinking

It's got the g36/ f2000 rail and the grip and scope of a steyr aug

Yeah right, the gun looks really garbage

It's like something you'd see in a cheesy futuristic movie from the 90s.

mfw VAG-72...

It's been a while since I've read the book The Black Rifle, by Edward Ezel (spelling?), but I thought it was stated in that book that the purpose of the slow rifling was to cause the petals of the sabot to separate reliably and consistently from the flechette, so as not to effect the accuracy too much. But the corkscrew flight path makes at least as much sense as that, and I know that some air-to-ground rockets have had spin imparted to them for that reason.

I think the flechette design could be improved using modern design to provide far better stability and dynamics using Engineering AI techniques for accelerated generational improvements, then using industrial 3D metal printing.

​@@user-yv2cz8oj1k there is no need to use AI to design something that simple, a half decent engineer whose been properly briefed on what you need could design one in traditional cad software in like, a day.

@@justcallmenoah5743 There isn't a total necessary use, an engineer can knock out something basic, but AI can give options to a set of requirements to provide design options a human engineer may not think of, and can provide iterative generational designs to provide rapid development of improved designs.

@@user-yv2cz8oj1k dude, it's a dart. What possible design variations would there be over what an engineer could think up relatively quickly? Want multiple variations about fin size, count, and weight? Just add parameters to your model, takes about 5 minutes total and you can generate new models with any number of parameters in milliseconds. Want variable infill, which would only really apply to 3d printing, although it could be a useful technique to have lower infill at the back, allowing the penetrator to stay dense while dropping the total weight, parameters, about a 5er. How about variable thickness across the width of the dart, or maybe even variable length, each a handful of parameters. Basically my point is that the design of a small metal dart is so simple that you could devise an incredibly customizable and tweakable model in basically the same amount of time it would take to make a one off model of a single idea. AI would be entirely unnecessary for something this simple.

It is the Pallet Rifle for the Evas

That’s really Interesting!

great story! Any chance the Singaporean rifle was the SAR-21 used today by the military? It's a Singaporean-made bullpup that resembles the AUG somewhat; used it for two years during my service.

@@glenn.c It was probably an SAR-80, which was an AR-18 clone made by Chartered Industries Singapore (now ST Kinetics). They hawked it around a couple of countries in the 80s, but they didn't get any large orders outside of Somalia.

Ahh yes, the Austreyr

I was an infantry instructor in the Austrian Army for several years in the 90ies, so I trained hundreds of guys on the AUG. In addition to that, my dad was a General and for most of his career, he was responsible for choosing, testing and selecting equipment for the Austrian Army - among many other things, the AUG. He used to tell me this story that you could bury the AUG in sand, leave it for a while, and when taking it out again, it’d still fire without a hitch. While neither the M16 or the G3 passed a similar test. Don’t know the veracity of this, or if it was just an anectote, but in my experience, both in hot summers and very cold winters, the AUG hardly ever failed or misfired.

I remember a lot of articles like that at the time - there was also an emphasis on less-lethal weapons because the envisage future conflicts were Somalia-style policing operations. It was the heyday of Metal Storm and airburst 20mm grenades and so forth.

Well, for a cat...

Futuristic weapon

Cat It’s so fackin ugly

Seems almost like an open-bolt action.

I would love to see someone remake this mechanism to fire brass, they would be cheap to produce.

Now that you say it, yea!

Heck yeah! This is probably lo y do to them not being allowed to have em, so they are great at "ogling" and drooling over firearms.

@@mikestavisky8009 I do feel in this specific case it was chosen because of the flechette thing, as it needs to go through hard to penetrate energy shields. Pointy=better penetration is my guess for the reasoning at least Might just becuase it looks cool and futuristic

A flechette firing weapon makes sense at an Eva's scale because it would need to penetrate armor and a lot of it. If the ACR's flechettes were scaled up to weigh 660kg instead of 0.66g but maintained their muzzle velocity of 1450 m/s, they would have kinetic energy of 693 MJ, twice that of the USS Iowa's 16 inch guns firing 1225 kg shells at 762 m/s. Of course it doesn't compare to the positron rifle charging up from Japan's power grid (187 GW) for 30 minutes, then letting it off in two 4-second shots (effective power of 42 TW), but still.

@@d.akross3639 i had an extremely similar line of thoughts, especially since the pallet rifle is intended to take down an Angel's AT field before going in for a killing blow if I remember correctly

The G11 was only three burst mode. That was the whole point. Ian explains the recoil effect in the video.

@@IainDelaney what?? no, it had semi and full auto

​@@IainDelaney Don't you remember the part of the video with the selector lever?

Ah yeah, that old "we don't kill, we incapacitate" motto. Our NCO repeated it like a mantra, the guy on the shooting range always told us "it's fine in training, in an emergency, nobody cares about it." Where were you stationed? Ex-recon company from Bleiburg here.

Is this the 5.56mm doctrine that states by injuring one enemy you incapacitate another 1-2 enemies because they now have to give first aid?

Give me a nice ACSS optic or a good old fashion cross hair any day. If I want to aim to wound let me aim to wound not just hope it goes somewhere inside of a 21 MOA ring sheesh. nuts you guys trained that way, I remember first getting a look at an AUG's optic and being baffled how people managed hits with it, but it seems to work really well in the hands of Austrian armed forces so who am I to bitch? if it gets hits it fits. Thanks for the background information on the Donut of Death Mister Klug.

@marissa bolino Regardless of how you feel about it is a genuine doctrine used by genuine militaries. It's not the first time militaries have espoused stupid beliefs in saying that what makes you the one to tell them their wrong?

Such is the neverending arms race between offensive technology and defensive technology. We are at a turning point in history where defensive tech, kevlar body armor and the like, is beginning to really take control and shape the future of that arms race again for the first time since the era of ye olde platemale

well this thing could possibly solve both problems, flechette design does wonders for AP capability and makeing round go fast is one the ways to extend range

300m is about 3 football fields, assuming a McDonalds cheeseburger.

brockhampton so did I lol

Me too i think thats the aug a3

Andrew Burke I was thinking the same thing. This rifle looks like with some improvements would be a great rifle. I love how simple the mechanism is.

@@frankdindl790 One improvment I could think of was maybe making the flechette out of tungsten, make it a bit heavier and give it better penetrative capabilities, bring it up to maybe 25 grains

TheOzTurkish With the AUG’s donut of death, if you aim center mass you are gauranteed a hit at 400 meters and below. Great system!

nirfz it was 15 years ago since I last shot one, it might have been zero at 200, I'm pretty sure it was 100 though

There are no points marked, but you can still hold off by mentally picturing them. Been a long time since I last shot an F88 but I never had any problems with hitting what I wanted to (then again, nothing I ever shot it at was making a conscious effort not to be shot) out to 300m. During the first firepower demo I saw with the rifle it was being used to engage point targets out to about 800, obviously with very good weather for it.

Using the F88 sight, zero at 100, at 300 shot fall is at the same point of aim. After a few shoots I learned to aim about half a reticle (donut) low off the point of aim to hit the csm at 200.

When I was a member of the Austrian Armed Forces ("Bundesheer" in German) around 2000 we used the Steyr Aug and they (the instructors) told us, that Austria and it's weapon manufacturers were not allowed to use crosshairs in optical targeting for international legal reasons according to stuff related to WW2, so the ring was used. Don't know if that's really true.

It's a scaled down model

Evangelion used ze G11 though lol

He isn't talking about the JSSDF rifle. The EVA rifle was based on the ACR

Leonov Martinovich what do you mean by "based on"? Isn't that real?!

Giant humanoids piloted by emotionally stunned teens aren't real fren

maybe, but doubt it, they are designed to survive chamber pressure so it would be kinda wierd if you could deform them with spring tension

No.

yeah, whats going on back there?? my interest in the door situation is equal to that rifle.

@@philiproszak1678 this comment is why I'm here. What is going with that Door?

@@Jasonliggett69 yeah man, you're asking the right questions.

When I look at it, the first thing I think of is how that extractor-free action could easily be adapted to caseless rounds--without all the complicated clockwork of the G11.

@@smorrow How does a rotating rather than sliding chamber aid the hyperburst?

@@smorrow Interesting. I wouldn't have thought the magazine being horizontal was necessary--for instance, the AN-94 (which has the magazine and action recoil together for the same reason as the G11) used a more conventional out-the-bottom magazine, albeit with a weird internal configuration to improve cartridge presentation speed.

Are you saying metric is superior, shame on you. (:

Using Imperial measurements makes Jesus cry. And this guy sux at Maths/ Unit Conversion (which is why America crashed one of their Mars probes).

Yes please! I have no idea why they exist. I have been looking but can find no advantage over the conical bullet

@@tulipalll extreme velocity and armor penetration relative to the weight of the projectile. It's the same reason why APFSDS rounds are shaped in much the same way. As a couple of additional benefits, due to its shape and very high velocity, it has a tendency to dump most of its energy early in a soft target and will sometimes shatter in the process, giving you more stopping power and less overpenetration, which seems counter-intuitive, considering its relatively better armor penetrating capabilities. The other couple of significant benefits are extremely lightweight ammo, especially with the polymer case, and much less bullet drop, again due to the very high velocity of the projectile. The downsides are mostly due to the nature of flechette-type round at this size and with the goal of cheap manufacture. As another commenter pointed out, the slow spin given by such shallow rifling is actually to compensate for any slight manufacturing imperfections in the flechette, not to stabilize it in flight, because it behaves more similarly to an arrow or dart in flight than a bullet. Any slight difference in the size of one of the fins will give the flechette a curved trajectory, so by giving it a slow spin, you instead turn it into kind of a corkscrew trajectory. Depending on how significant the corkscrew is, this can actually affect accuracy quite a bit. The only way to really compensate for this is the same way they account for it with the large APFSDS rounds used in modern Main Battle Tanks: Precision Manufacturing. You have to machine each round with extreme precision, which is justifiable for tank rounds because they're big and expensive and fired from a smoothbore cannon, etc. It is not as justifiable for an infantryman's rifle cartridge, where you want your ammo to be cheaply and quickly mass-produceable. TL;DR flechettes have better ballistic properties in theory, but have downsides that cost too much money to fix in practice. I do wonder if flechette-type cartridges are more viable now, given the last 30 years of advancement, though. Especially in regards to the durability problems with the polymer case that Ian mentioned, as well as the precision manufacturing issue I mentioned above. Are we able to mass produce something like that more cheaply now or not? Only time will tell.

Because the APFSDS concept just doesn't scale well to small arms. 1. Shotguns trying to fire a bore appropriate APFSDS projo would almost invariably explode due to the pressures involved with driving the projo to the velocities where the concept works better than "traditional bullets". Shotguns are invariably designed with much thinner walls in the chamber and barrel, because they operate at pressures under 12K PSI as opposed to over 50K PSI for a 5.56x45mm. If you build the shotgun to that pressure standard, it would be ridiculously heavy...and the Cube-Square law means your pressures for a "shotgun" sized projo will be higher than the "rifle" version - there's a reason the Rheinmetall 120mm runs near 100K PSI. So, your shotgun would likely have to be designed around a chamber pressure of [gazes at ceiling, SWAGs it] probably north of 65K service pressure. That's a LOT of meat you need to avoid it grenading on you, especially wrapped around a 12 gauge sized cartridge... 2. Bundles of flechettes (such as you find in some artillery and rocket rounds, and has been trialed in shotguns and 40mm grenade launchers) doesn't work, either, even when using the exact same flechettes you use in your artillery rounds. There's a variety of reasons for that, but every time we try it, we find it *at best* no more effective than plain old buckshot pellets (and generally worse). 3. For precision fire, the APFSDS simply doesn't scale down very well, because almost imperceptible imperfections that don't matter on the APFSDS projo for a 105mm or 120mm tank round are fatal to accuracy and terminal performance on a projo small enough for an infantry "rifle". And you really can't do even the level of QA inspection on them that the tabk rounds would get, due to production volume and cost - you're trying to crank out *billions* of rifle rounds before you even field the gun, whereas the total production volume of a tabk cannon round is much, much lower.

@@geodkyt 1. "...to the velocities where the concept works better than "traditional bullets"..." I don´t understand this, can you please explain further ? Let´s say you do take a traditional shotgun and make undersized ammo for it like an APFSDS. You use the same pressure as before. An undersized round should be lighter and given the same pressure should reach higher velocity and because it has less impact surface should penetrate better, give the material is hard like tungsten or similar and the rod is long enough for stabilization resons. 2. Yes I thought so too when I saw the Russian flechette bombs, most of the small darts don´t hit in the right angle either and they seem to be too short to be stable enough, I too wondered why they don´t simply use balls instead. They probably made them and didn´t bother. 3. Yes that is a very good reason, the quality would have to be superb which is not feasible for a low cost item like simple bullets.

The ACR optic could be switched from 1.5 to 3.5x by twisting the eyepiece.

You might be surprised to find out that the U.S. military is now strongly pushing development of polymer case-telescoped ammunition (PCTA) very similar to the Steyr ACR's, but loaded with conventional bullets instead of flechettes and using standard centerfire primers. Look up "Textron," "LSAT," and "CTSAS" for more information.

I was gonna say something to this effect. This rifle's operating mechanism looks like it would be a good base for a PCTA rifle. Attempts to use saboted ammo usually suck in small arms because we can't manufacture the ammo consistent enough for good accuracy compared to larger weapons using sabots, or small arms using conventional projectiles. Currently used rifle actions don't do great with telescoped ammunition, so simple designs like this with few moving parts and seemingly low reciprocating mass during operation are interesting.

'PCTA' yeah right. Imagine this kind of ammo gets adopted. During the change over troops will say, "do you want circumcised or not?"

That and we dont always see the military prototypes as their happening

The telescoping ammo and the XM-25 with its airburst capability. There is defenetly a progress.

They might not have been fielded by the US Army in 1996 like they envisioned, but at least they can rest easy knowing it helped defend humanity from the Angels in 2015 in the hands of monstrous demi-human chimeras.

I'm pretty sure the mechanical designers of Eva were looking at the ACR program for their vision of future military units since the Eva units use giant Steyr ACRs and the JSSDF soldiers in the movie use HK G11s

+Strikerrr Common in sci fi to use the next hot flavour of thenmonth gun. SG used P90s, nowadays everything uses Kriss Vectors.

There is nothing better than the M41-PulseRifle

I'll go with the FN SCAR 7.62×51mm NATO for the JSSDF

As long as no length is lost from the cartridge on firing, and the chamber isn't longer than the fired case than it shouldn't matter what orientation it is when fired. It'd be a similar concept to a full length ejector on a revolver, but with less to get hung up on.

Maybe the cartridge is thick enough that it can't move through the chamber unless pushed?

Why Jay . I think so. It must be a tight fit. Thats why when all the parts raise their temperature due to sustained fired, that plastic cartridge ( nylon I suppose) may be subjected to some deformation or sticking into the chamber. These are all suppositions. Cheers!

Steyr makes very reliable guns since way more then 100 years. I am sure the gun itself with its mechanisms are flawless, if there were problems, my bet is on the not finished refining of the ammunition specifications and not optimised production line for that unique type of ammo.

I was thinking the same just now..

Bunkyboy 91 no because the rim locks against the barrel and brass itself expands and stays expanded until it cools whereas this polymer case probably wasn't very intact when it exited the front of the chamber

Maybe not too standard; If the firing pin breaks, and you're not sure what happened and cycle manually, you'd have a tip of a bullet pressing against a primer.

Steyr patented a rising chamber mechanism for bottlenecked cartridges. It would eject downward behind the magazine. patents.google.com/patent/US4739570

The madsen rifle (rekylforsøgsgevær) functioned in sorta this way with a rimmed cartrige

Well they're used for anti-tank rounds because of the speeds they can reach. I would imagine that if body armour improves, flechettes or atleast saboted rounds would become more common.

A lot of anti armour rounds are apfsds aka a heavy metal flechette surrounded by a sabot.

I'm not exactly sure what you mean, but isn't a flechette just a long metal dart?

Ah I see what you mean. My point was that those darts could be down scaled to rifle size to defeat body armour. Thanks for clarifying.

Such a polite interaction!

the LSAT got the idea from the Steyr ACR, both round and action.

Same here. One accidental full burst ONCE for a full company. And that guy was an idiot anyway.

in my serve time in austria i could easily fire single or auto. i prefered prefered to shoot doublettes, which was very well doable. push trigger through for a short time, so that 2 rounds are triggered. so you have 2 pretty accurate rounds heading to the enemy, the third one would not be accurate enough anyway. Only flaw with the trigger mechanism was, that its too hard to push. if you pull the trigger to the pressure point, and then above, its so hard, that your gun will move a tiny bit. so high precision firing for long distance shots is not easy with this gun. It may be, that the australian trigger pressure points are way softer, then in austria, so that a bauer lounging with sausage fingers, with the sensetivness of an crocodile may trigger full auto more often by accident?

Also referred to by the infantry as the "Numpty Button" or "Idiot Button"; Because only idiots needed it

The LSAT is basically this in the action and ammo.

replace with long-ogive spitzer boat-tailed round.
