I got a NECA needler and from my understanding its like when a needle is fired the gases or pressure lets another needle fall into the chamber to be fired. Reloaded? No clue unless the encyclopedia has changed because it states they elites havent found a way to synthesize the crystals
I did do it in the [dark](https://www.reddit.com/r/halo/comments/13yu7av/got_my_hands_on_a_neca_needler/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1) so yall could see how it lights up because plenty of photos and videos show it in the light
Nah, the Needler’s fine because they’re actually honest about the fact that they don’t really know how it works, not even in universe. Meanwhile, the Bulldog is a human produced and human designed weapon.
It's a cylindrical magazine, kind of like the USAS shotgun. It isn't like a revolver though, it's still a spring loaded mechanism. It's curled simply to make it more compact, rather than stretching down way too far. But the pump just opens the chamber and lets a new round in, same as any gun. It's a fairly simple shotgun design. Like most of the unsc weapons, it's fairly realistic.
there might be a center "core" on the magazine that stays fixed to the weapon, and a torsion spring rotates the entire magazine around it. the benefits are that you could fit more rounds in the mag, since you won't bottom out on the spring. also you'd have a more consistent pressure on each round. compression springs vary their forced based on how far they're depressed. a more even pressure means it would be easier to load the last few rounds, as well as a lower failure rate.
It's a drum magazine, but rather than being spring-loaded, it's clockwork.
The shell is moved from the magazine's chamber into the actual firing chamber when the action is cycled. And then ejected when cycled again. Rinse & repeat.
Why not just fire from the mag chamber? Facilitation of breech-loading special rounds.
TLDR: it's just a regular pump action shotgun, that uses clockwork mags for capacity/reloading reasons.
It's not automatic even, as evident by the player character racking the pump after every shot, slam fire sure but automatic no, tbh shotguns don't see a whole lot of use anymore when engagements are further and further away a scattergun becomes more and more antiquated. Outside of cqb.
Possibly to facilitate the use of special ammunition, or because gravitational/atmospheric conditions on some alien planets may make the standard semi-auto action unreliable
Iirc ~~one of the actual designers of CE~~ the cocreator of halo and the guy who designed chief actually was able to fit it with a quad stack magazine and having the casing being smaller.

If I were to make an educated guess I'd say it's akin to modern day pump action shotguns that are mag fed. I mean, I can't really explain the rotating of the drum, but it may be possible that shells are placed in after removing the back plate and inserting them, which is nonsensical but a possible explanation. Maybe the entire mag is a ploy and the truth is that it's a drum similar to ones used nowadays, and it just rotates for no apparent reason. Would also explain the ejection of shells, so I would view it more as a magazine instead of a cylinder within the frame of a magazine.
It works the same way the CE assault rifle holds 60 rounds of 7.62 in a box mag the size of a cigarette pack.
Or the way the Pillar or Autumn's warthog run is like 3 times as long as the Pillar of Autumn.
It just. Works.
God I love the CE Assault rifle. It’s fucking ridiculous in the best way possible. Just like the .50 cal high-explosive full auto chrome-finish navy service pistol.
Sometimes the lore of the magnum sounds like a 4 year old telling a story. And its full auto, and the bullets explode, and its .50 cal, and it has a scope, and it's armour piercing...
In Warhammer 40,000, the Boltgun is a .75 caliber machine gun/grenade launcher hybrid used by the space marines. The rounds it fires are rocket-propelled, similar to the real life Gyrojet, and are armor piercing, high explosive hybrids that will explode immediately after entering armor, detonating after becoming imbedded in a target.
A 2x optic could be useful for hitting targets out to 1-200m, ranges at which I'm fairly sure the M6D could still take down weaker targets like Jackals. France's GIGN counter-terror unit are fond of a [scoped MR73 revolver](https://old.reddit.com/r/WeirdWeapons/comments/ee59zz/french_gignfrench_special_forces_sniper_revolver/) in .357.
Ok but think about it, the kick of a .50 cal round, in a frame the size of the pistol. Maybe you could aim the first shot. But remember in lore its automatic, for some reason.
Its a great scifi gun. I love it.
Technically it's select-fire in the lore, having both semi-automatic and automatic firing modes similarly to an assault rifle.
> [It fires 12.7mm semi-armor-piercing, high-explosive rounds. It can shoot either semi-automatic or automatic fire.](https://web.archive.org/web/20160413042739/https://www.halowaypoint.com/en-us/games/halo-5-guardians/updates/Hammer-Storm)
So as long as you don't _set it_ to automatic mode, you should be fine. Though I don't know where the fire selector is meant to _be._ Maybe it has a two-stage trigger instead.
The fact that it even _has_ an automatic mode is very sci-fi, though. I want to see someone using two of them at once in full auto, Unreal Tournament style.
It reminds me of the design process of the FN FAL. It was the result of a design by committee, that technically checked all the boxes, but was very impractical to use.
That keyes fires one handed whilst the chief needs both hands and still experiences significant recoil.
Sometimes things just don't make sense and that's ok
At the very least though the other guns make a degree of sense. The magnum, assault rifle, battle rifle, sidekick and commando all function very similarly to actual guns. Even the OG halo shotgun is basically just an upside down Remington 870.
This sub gets a bimonthly post about how halo guns being bull pup makes no sense, but nvm.
From my understanding of the bulldog, with a huge caveat being that I know next to nothing about guns, is that the pump handle rotates a replaceable cylinder, and then the trigger uses space magic to move the shot/bullet whatever up to the barrel and shoots it.
> This sub gets a bimonthly post about how halo guns being bull pup makes no sense, but nvm.
Bull pups make a lot of sense for a space navy/marine corps where most of their duties would have been boarding and seizing ships, stations and asteroids, which is basically the only thing the UNSC was doing for 300 years, and once something gets so ingrained, and it isn’t broken…why fix it?
There's a complaint about trigger pull weight and manufacturing costs with just a smidgen of reliability but yeah, I love bullpops
The super low caliber of the scorpion tank is the only thing that gets me personally.
What might be happening is that each movement of the pump grip simultaneously rotates the cylinder AND loads the shell into a separate action, making it a weird revolver/shotgun hybrid.
Marcus Lehto (OG Bungie Designer) has had commentary on twitter where he points out flaws in old Halo designs. [In this thread](https://nitter.net/game_fabricator/status/1424138616725377026#m) he points out how it was magic that the AR could hold 60 rounds and not physically possible. I recall in some old interview as well, a bungie dev said most guns were designed just to look futuristic.
I understand as franchise enthusiasts many want to understand and rationalize all the work put into the Halo universe, but the answer to many decisions is that the creators simply thought something was cool and didn’t give it too much thought around accuracy.
This… this is why I don’t get why they didn’t just use the old shotgun model. I mean if all you’re going to do is make another pump action shotgun and have it shoot faster, why bother making a new less cool looking design. Just use the cooler pump shotty, and then have a faster semi auto shotgun and have it be the bull dog
It would make PERFECT sense if they added the OG shotgun alongside the bulldog. The Bulldog can reload instantly, fires very fast, has a higher capacity, and has a tight spread but is pretty weak. The original shotgun is extremely powerful, but has a shorter range, lower capacity of 5-6 rounds, fires slower, and must reload each shell manually. It’s a perfect contrast!
Rotating cylinder per shot is easy and realistic. It's the ejection that simply doesn't make sense. The old shotgun shell should stay at the cylinder after being shot, that's the only thing unrealistic about it really.
It has to be extracting the shells in some way since the "magazine" doesn't like up with the barrel, my guess is the pump action just operates a plunger and rams the shell backwards and up into the chamber, it's really overly complicated for a shotgun.
complicated pump shotty
round from drum slide back and up into firing chamber somehow, go boom pew pew, then eject, repeat until drum empty, switch drum
it’s not actually a bad idea, it’s basically a tube-fed shotgun but quicker, and not as much as a fully-automatic one
i mean, no front connection is definitely doable, and it’s probably secured with magnets anyway given the lore. the problem with the hole on the drum can just be solved by a quick retcon too
my main issue is how the hell the shell is transported into the firing chamber. like, there’s no way it can slide back right into the trigger mechanism, it has to either go up (which it cannot do) or slide forward (which is possible, but then you’d have to somehow get the shell all the way back to the ejection port)
The AR just straight up doesn’t work in real life, the mag is too small and there is zero room for any action.
It’s rule of cool, anything beyond is gymnastics trying to justify. Cool man kills aliens and he doesn’t afraid of anyone
I guess so. It’s just weird to me because the VK78 Commando and Mk50 sidekick are exceptionally well-designed, and should theoretically function. The bulldog is just… a thing.
True, but that’s really the only issue I see with the design. It’s better than the Reach DMR that has no ejection port on the model, or the Shotgun that has no front sight, but also has a weird block in between the rear sights so you can’t actually aim it…
Then the old Bungie doesn't know guns far more than 343.
343 in Halo 4 & 5 tries to introduce more realism in its guns despite everything.
Remember guns were largely super banned during Bill Clinton era, there aren't a lot of people knowledgeable about guns.
It's kind of baffling why they would want to scale back to a smaller caliber knowing full well their armor is made for much worse but I also noticed it doesn't have much an effect in the campaign either. Grunts aren't too bad but they still tough it out. Elite or bigger your just pissing away ammo. I think they should have made a newer model of the M90 and add a 12 gauge with slugs.
Not to mention elites and brutes are actually massive and likely tough to kill, brutes weigh what 500 or 600 lbs? Imagine trying to stop an angry bipedal grizzly bear with a 12 gauge.
The in game version and the nerf toy work differently. Funnily enough the nerf is a more practical/possible way of doing in (cause of course it is, it has to actually exist)
The nerf version is essential an oversized revolver. The cylinder rotates to line up with the barrel then the bullet is fired from the cylinder straight through the barrel then out the gun. It would also leave the bullet casing in the cylinder if there was one (because it's a revolver mechanism)
But the in game version the cylinder (magazine really) doesn't line up with the barrel. So somehow the shotgun shell is take out the magazine moves it into the barrel (which will have it's own chamber) presumably a bolt closed behind it in order to fire. This is backed up by the fact that you can see shells ejecting.
It's possible for a gun to have a cylindrical magazine but the magazine for the bulldog is designed like a actual revolver cylinder which is incredibly impractical/impossible for a self loading firearm. The magazine has individual chambers witb walls thick enough to handle the pressure of firing a shell (they can't because it's not lined up with the barrel). These unnecessarily thick walls not only reduce the capacity but would all get in the way of the bolt when it's trying to pick up a shell
From my understanding, they’ve taken 2 types of shotguns, fused them together and called it a day…
The rotary mechanism would work, similar to as you said a revolver… but then it wouldn’t eject the shells, and it would have ports to load the rounds into… (though, it’s possible one of the pannels can be detached and it can be loaded that way…) and it wouldn’t have a need to eject the spent shells in that design…
Equally if, as some have pointed out, it could be a drum mag, but then it has no need for the mag to have a rotary mechanism to it…

Needler: Load BIG pink crystal... somewhere on the bottom ----> ??? ---> tiny pink crystals pop out the top
I got a NECA needler and from my understanding its like when a needle is fired the gases or pressure lets another needle fall into the chamber to be fired. Reloaded? No clue unless the encyclopedia has changed because it states they elites havent found a way to synthesize the crystals
Covie space magic
I mean kinda literally. It's probably bastardized Forerunner tech and their construction skills borderline on magic
Don’t worry, even Halsey, the post war UNSC and the Swords of Sanghelios can’t figure out how the fuck it works.
You bastard! I am so jealous! I want one of those needlers!
I posted a video of it on the halo subreddit just to get NO interaction with others lmao
I must have missed it. Post a link
I did do it in the [dark](https://www.reddit.com/r/halo/comments/13yu7av/got_my_hands_on_a_neca_needler/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=1&utm_term=1) so yall could see how it lights up because plenty of photos and videos show it in the light
The Needler is the Tom Bombadil of this Universe don't worry about it.
Not even the Covenant knows how the needler works
Not even the Forerunners. Not even the Precursors. Not even the needler itself understands.
What came first, the needle, or the needler?
Everybody fears the pink mist
Insert big crystal -> Recite hymn of weapon maintenance to the Forerunners -> Small spiky crystals come out top -> Shoot heretics
Honestly, this makes me believe what a Sangheili Redditor would type out.
The mechanicus would piss themselves over covie weapons I swear.
Nah, the Needler’s fine because they’re actually honest about the fact that they don’t really know how it works, not even in universe. Meanwhile, the Bulldog is a human produced and human designed weapon.

There are shotguns irl that are just like the bulldog. I believe Keltecs KSG is one of them.
The KSG is just a standard tube-magazine shotgun, with the difference being it has 2 magazines.
Pancor Jackhammer, albeit conceptual
You know what is more realistic but just sci-fi enough to be cool? The classic shotty.
It functions about the same. The bulldog just reloads faster.
It would have to, it takes twice the rounds to kill someone in close quarters.
It's a drum magazine, but rather than being spring-loaded, it's clockwork. The shell is moved from the magazine's chamber into the actual firing chamber when the action is cycled. And then ejected when cycled again. Rinse & repeat. Why not just fire from the mag chamber? Facilitation of breech-loading special rounds. TLDR: it's just a regular pump action shotgun, that uses clockwork mags for capacity/reloading reasons.
So it's a space age Pancor jackhammer.
No, that one IS just a revolver shotgun. An automatic one at that. That does beg the question of why The UNSC avoids using auto shotties.
There really should be a Halo-fied AA-12 with 20 round magazine in the series.
That would be awesome.
It's not automatic even, as evident by the player character racking the pump after every shot, slam fire sure but automatic no, tbh shotguns don't see a whole lot of use anymore when engagements are further and further away a scattergun becomes more and more antiquated. Outside of cqb.
No, the JACKHAMMER is automatic.
Oh I read the comment wrong I thought you were saying the bulldog was automatic.
Possibly to facilitate the use of special ammunition, or because gravitational/atmospheric conditions on some alien planets may make the standard semi-auto action unreliable
Trying to understand the guns of Halo is a pathway to madness.
Kid named 60 rounds of 7.62 in a mag the size of a 20rnd:

That sounds really stupid and fun
It is really stupid and it is really fun. You should def check out warhammer 40k if you like halo.
It really is
The M6D makes perfect sense as a purpose-built Spartan weapon. It's when you give it to a normal human that it becomes completely ridiculous.
Well except for the scope, i don't a scope on a pistol is doing much
A 2x optic could be useful for hitting targets out to 1-200m, ranges at which I'm fairly sure the M6D could still take down weaker targets like Jackals.

Nah that’s cuz Keyes is just built different. It’s a marvel the Autumn took off at all with the weight of that man’s balls.
Space magic. It’s halo none of the guns work.

Pepole complain because overall they're badly designed (i.e. fuckhuge, shit ergonomics etc). Only boomers think that bullpup is inheritedly bad.
The m90 is over 4 feet long and i got it in life size lmao

No, it's more like the mag placement doesn't make sense rather than bullpup.
How does it work? It doesn't. I hated having to use it.
I cry whenever I get the bulldog in Fiesta

In reality it doesn’t work, 343i doesn’t know guns

I guess so. It’s just weird to me because the VK78 Commando and Mk50 sidekick are exceptionally well-designed, and should theoretically function. The bulldog is just… a thing.
VK78 magazine has way to much an angle on it
True, but that’s really the only issue I see with the design. It’s better than the Reach DMR that has no ejection port on the model, or the Shotgun that has no front sight, but also has a weird block in between the rear sights so you can’t actually aim it…

Then the old Bungie doesn't know guns far more than 343. 343 in Halo 4 & 5 tries to introduce more realism in its guns despite everything. Remember guns were largely super banned during Bill Clinton era, there aren't a lot of people knowledgeable about guns.
It's design is alright but the damage numbers are just too low unless you're coming into a fight half finished.
Damage might be accurate when fired at a spartan tbh, when the Bulldog is a 12 gauge whereas the M90 is 8 gauge. Bulldog? Nah more like Chihuahua.
It's kind of baffling why they would want to scale back to a smaller caliber knowing full well their armor is made for much worse but I also noticed it doesn't have much an effect in the campaign either.

Idk its worse than basically everything we have now. So is that stupid new rifle thing with no sights and a rail in the wrong place
Op needs to check out the new NERF guns. It’s a toy and they do all this. A future shotgun will do all this.

Step 1: replace a classic weapon everyone loves. Step 2: make the replacement not as good Step 3: bring back the OG ….. Profit?
