IMR by AlexJJessup IMR by AlexJJessup
Concept I worked on at Sledgehammer Games for Call of Duty: Advanced Warfare. 

Property of Activision Blizzard, Inc.

*Edit* A number of people have asked how this works. I'll give a fairly detailed description, but remember this is a FICTIONAL design! All you would-be weapon designers, chemists and engineers, feel free to comment away but this is a design for an entertainment product!

The tube in the back contains "liquid matter." There are two parts to this, the first being a plastic material that makes up the bullet half of the round. The second part is unbonded aluminum and copper oxide. This is the back half of the round, and it is the explosive propellant. Aluminum and copper oxide either burns or explodes when combined depending on the ratios; this is how thermite is made. So the 'liquid matter' tube feeds these ingredients to the printer, which is the removable black thing on top. The printer isn't really a printer, instead it casts sets of four rounds at a time. Remember, each round is front-half plastic, back-half explosive thermite. The rounds look like a blue cylinder, nothing fancy. 

After a set of rounds is cast, the four bullets get pushed up to a storage area in the front, where they are queued to be fed into the magazine. The magazine is the black tube with the brass charging handle. When the user needs to reload, the tube is rotated out and pulled back through the queue area. As it is pulled through, the printed bullets get loaded in, all lined up facing forward. This magazine tube is basically a combination of a shotgun tube and a P90 magazine. 

Once the bullets are loaded in the tube, they are spring pressed towards the back of the tube, where they are forced out a hole in the bottom into the chamber beneath it (a bit left of the barcode). When a bullet is in the chamber, an electrical primer ignites the back half of the explosive thermite, which in turn sends the front half through the barrel and towards the target. A small vent system clears the chamber of smoke and dust before the next round is loaded. I imagine that by the time you've exhausted the liquid matter tube, you would probably need to clean the chamber out, since tiny bits of melted plastic/matter would start to inhibit the operation. 

As for bullet ballistics, that is a complicated science and I'm no expert on it. I imagine that between the bullet being printed with varying density, and the heat of the thermite burning, the projectile could be engineered to become aerodynamic as it leaves the barrel. Sort of how a projectile from a rail gun burns off matter from the friction with the air until it's essentially an aerodynamic spear. Except that this would be moving at a slower speed, but the material of the bullet would be forced into an aerodynamic form because it's a) weaker than the metal from a railgun and b) heated by the thermite already. 

The liquid matter tube does contain a limited supply of material to make bullets with, probably equal to 10-20 magazines. Maybe less. But the purpose of it is not to have unlimited ammunition. A soldier carries the ammunition he needs for a mission, not as much as he can carry. Navy Seals take a surprisingly low amount of magazines on missions. The goal here is to a) remove the need for magazine storage on your vest, and b) to make the operation and reloading even simpler and faster for the user with less training. Speed reloading an AR15 can be blazing fast, but it takes a LOT of practice. This design, for the duration of a single mission, requires nothing other than what it already contains.

Though personally I only think this gun is ok in-game, the concept of a gun that literally creates ammo as you fight through the use of a 3D printer is mind blowing. You really bring that concept to life. Thanks man. :)

Really nice gun. I played it all the time on AW... till the gameplay was going bleh. May I ask a suggestion, please? Could you guys go back to old school cods? Like back in COD4. But I love the design of this weapon.

This would actually be a pretty workable weapon if the tech existed if you put it in a slightly different role; there isn't much advantage to liquid propellant or printed rounds in an AR with a fixed muzzle velocity and only one type of projectile: all you get is the lower density of liquid which makes your ammo physically larger for a given mass, and I'm not sure there's much benefit from dropping most of the contents of a soldier's chest rig into his weapon since it would result in an AR as heavy as a support weapon (back-of-the-envelope for 600 rounds of 5.56mm with 62 gr projectile and 26 gr powder is seven and a half pounds) and a gun that would require technician-level training for even a basic field stripping. I mean never mind the results of a stray bullet hitting the propellant tank D:

But in a sniper rifle with a computerised futurescope that could identify targets and if you had a way to rapid-prototype something like copper or tungsten (say by loading the gun with blank rods and running them though a teeny-tiny CNC lathe), you could basically handload every round and make a projectile ideally suited for every target. Would also be good in a shotgun with formed shot, flechettes or slugs since you could select the next round on the fly or have your gun computer do it for you. If the comp is smart enough it could even be set up to automatically form less-lethal rounds if it can't tell if the target is armed or not.

I don't think thermite as propellant would be a good idea, though: even if it didn't physically damage the gun, you'd need a plastic that wouldn't melt from exposure to the propellant to the point of fouling the barrel (especially if it isn't a smoothbore) but would melt when exposed to the 3D printer's heating element, which would mean you'd need a gun where the action needs more energy to run than the propellant generates. I imagine troops in the field would call it old smokey.

With an electrical primer you might as well use ETC (plasma) ignition which would give you the benefit that your propellant could be something that's inert under most normal circumstances, which would beat trying to deal with a metal-oxide fire if someone hits an ammo store. Hell, some theoretical ETC propellants you could actually spray them on the fire to put it out :)

As for the ballistics part, I think you're thinking of pyrophoric substances like depleted uranium which are self-sharpening because they burn down due to friction as they pass through armour, and that's not what a railgun does: the projectile is always a dart, it's just surrounded by a sabot so it fits in the armature and because the projectile isn't made of a conductive substance. The huge trail of fire in railgun test videos is the conductive armature separating as the projectile leaves the barrel and / or friction turning air into plasma at the tip of the projectile. I don't think heat applied to the back of a projectile could be used to reshape the front of it.

I mean don't get me wrong, I get what you say at the top that the brief was for a gun that regenerates ammo and if you knew a real way to do that you'd be off to the patent office rather than handing it to Activision.

The AW weapon I'm most curious about is the Tac-19, though: what exactly is that one supposed to be doing, is it a sonic cannon or something?

Great read, you hit so many points that I've considered when I first used and delved into the IMR. There is so much potential to where this fictional firearm can lead us in terms of futuristic weapons. (The CNC lathe idea is interesting).

I can agree on the exposed propellant tank, both regarding the weight and the obvious danger it poses being uncovered. However I guess we should consider the fact that most infantrymen in the AW universe are wearing exo-skeletal suits... Fairly surprised myself how this firearm doesn't rely on electrical initiation as a more effective primer mechanic, but like what Alex said, he isn't an engineer nor chemist on this matter.

With regards to the Tac-19, I think it's a concussive/sonic wave gun, considering the fact that enemies are violently forced to the ground when you score a kill in multiplayer.

Well, they do wear exos, but they're just the strength-booster type that attaches to the outside of the limbs, body armour is still pretty similar to modern and it's not like you're a tank in-game.

I love the way this weapon looks, the theoretical design is great too. I wouldn't have listed the tube as liquid matter though as all liquid is matter, maybe as propellent or just spray the elemental formula of the gas. As for the printing of the plastic rounds I think that's a great idea and we already have 3d printing I'm sure that tech will only improve. Even unfilled plastic rounds ready to be filled would bee safer to carry in the field for soldiers and weight much less than conventional bullets. If the plastic rounds were impregnated with charged metal fragments you could imbed the same charge into the rifling of the barrel with the same same weak charge to get the plastic round to float once chambered, perhaps even spin, granted once the round was fired the back end would flare out and touch leaving some  plastic behind, but if would be much less due to the repelling charge that floated the round and it would lower the friction and heat produced. I'm glad to see you guys don't just want them to look cool you put some thought into it great work.

This is really nice. The description is fantastic, too, and just reflects that extra bit of effort. On the realism note, I'm very skeptical of plastic being used in a lethal rifled bullet. Even if it were mixed up with metal filings for increased strength it would probably shatter/decompose under the chamber pressures. Even if it survived firing, I can't see plastic being any use against body armour or cover.

Hard SF-ness aside, I love the overall aesthetics of the gun. The slanted look gives it a very agressive feel - I can see it will handle best when the operator is leaning forwards, promoting a highly mobile style of shooting. Also interesting to see they way you've built the gas system into the actual upper receiver (at least, that's what I assume the forward-most post is for), which is both practical and cool looking.

I have to wonder if the artist is assuming plastics of the future will be able to endure firing. The first plastics weren't nearly as strong as they are now, so who's to say future plastics won't be as strong, or stronger than steel?

HSAR Featured By Owner Mar 15, 2015  Hobbyist Writer
It is, I suppose, possible (although extremely unlikely) that materials science would be able to sort out that problem - high-precision high-speed projectile manufacture in the field. But the problem is that you're placing constraints on the technology that need not be there.

Consider a world where technology allows for that. Then think how much more advanced body armour technology would be by then. Sure, you might have plastics that are better than current-day steel, but we'd probably have something for armour that was even better by then, capable of standing up to whatever new stuff we'd make normal bullets out of (which are, again, almost certainly better than something manufactured in the gun).

I should note that this is at a pretty high level of hard SF pedantism, and of course artists are allowed to take liberties with their assumed technologies.

Vernon682 Featured By Owner Edited Mar 16, 2015
But then what if conventional bullets are then outmoded by that armor? That leaves only the AE4, EM1, and the EPM3 as the only ones that cause damage, maybe by then said bullets have some sort of explosive core that ruins the armor, and the 4 round burst of the IMR is so the first bullet kills the armor and the last 3 are the killers. It would explain the 4 round burst, but then I'd have to explain the AMR-9. Maybe it fires such a big burst to compensate for the bullets lack of power. Or maybe the armor is normal because the IMR is like a working tech demo and armor hasn't had a chance to catch up to the bullet it uses.
This is over the top levels of pedantism but it's an interesting thought experiment thinking about the tech that goes behind this currently implausible rifle.
