>>33527495
you'd have to put contacts up the whole rail, which might get messy, but not a bad idea.

So I don't detail the thread, I'll put my idea here: A falling block pump action shotgun that feeds from a tube magazine in the buttstock. It could be a cheaper design than a budget pump gun of today, or at least that's the point of it.

>>33527479
Downsized M14s in 6.5 Lapua. I guess it'd be in between an M14 and mini 14 in size.

A revolver that you can change cylinders like magazines. Sure it's not a good idea but it'd look cool.

piston* dammit

Cut down .50 BMG brass to make rimless 12 gauge shells, design double stack 12 gauge gun/magazine

Sten submachine guns were made on relatively crude equipment for a pittance back in the day.

I'd think that someone would have come up with an updated design that would use modern available magazines and easily available parts.

The problem with assembling the old Sten parts kits was not the receiver-- which was just a piece of steel pipe that you could cut with a dremel-- but the tricky welds on the barrel assembly and ejector. I think that if you could come up with a Sten-like legal semiauto that you could assemble with screws, bolts and threaded parts, it might be close to the popularity that the AR build business enjoys.

>>33527569
I had an idea like this but the cylinder acted like the enbloc clips in a garand. Barrel is on the bottom similar to a unica and no bridge on the top so you pop the cylinder in from the top and start firing then when the cylinder is empty a tap pops it out automatically and you can just drop in a new one. Like a unica/fosbery it'd be an autorevolver.

>>33527479

Electronically-controlled revolver using specialized ammunition that contain multiple shots per chamber, effectively doubling or even tripling the capacity of the revolver wothout sacrificing the power of the cartridge or any of the other advantages of the revolver.

>>33527880
How would the rifle know to eject on empty?

It'd have to feed from the cylinder like a magazine instead of a revolving chamber like on normal revolvers to even be feasible.

Which seems really beyond impractical, but probably a very cool Forgotten Weapons episode.

It'd have to be insanely complex, with locking the rotating cylinder and enbloc-style ejection of such a heavy piece of metal.

Unless it just fed from a lightweight revolving, cylindrical enbloc clip.

A clip loaded Shotgun. Using an M14 or SKS action. You could clip load it from the top or replace the magazine. It also has a nice low bore axis.

What if you had a gun with no grip, and no stock?
To replace that, there would be belt and metal connecting your arm to the gun, and trigger operation would be similar to an animatronic bike chain hand.

The simple idea is that it's a literal hand cannon.

How would this gun be classified under current legal definitions?

Take an M4 and put the magwell on the side, bend the mag at the top to feed at 90 degrees, integrally build it with an m203 where the magwell was.

Doesn't do anything but i use to build clay armies with toothpick guns around the time COD4 came out and and i was into Stargate SG-1/ Atlantis. So a chopped back AR/P90was the desired builds. I was WAY too poor to know what a hobby store was due to no internet and basic bitch cable so fight me if you think making clay men and women is weird.

>>33527788
The problem with Sten repros (and similar submachineguns) is that they fire from the open bolt. It makes them a shitload easier to built, but the ATF decided that they're too easy to convert to full retard, so now you're not allowed to build them in burgerstan. Closed-bolt firing only, desu.

Gas operated handgun.

>striker fired
>short-stroke T-shaped piston in a gas-block housing underneath the very front of the barrel
>piston forces slide back ~5mm

>cam track on inside of slide lifts up the locking arms
>locking arms then slot into the slide, with residual chamber pressure / recoil force pushing the breechblock and slide back to cycle the weapon

It'd be a practical way to make a gas operated pistol that's smaller than a deagle but can handle a variety of high power rounds, such as .50 AE, .460 Rowland, 5.7x28mm, hot 10mm Auto loads, .38 Super, etc. Being a short-stroke piston design, it could still run on the gas from lower power rounds like 9mm or .45 ACP, too.

The inherent accuracy of having a fixed barrel and frame-mounted sights will mean plenty of potential for a good target pistol.

I remember reading about how some guy had a revolver which could fire a range of calibres. The cylinder was sprung in such a way that the breach clamped around a the brass. So use a similar system in a solid stick mag that traverses horizontally (like the bastard gun in metro 2033) and you have a SHTF gun that can fire whatever ammo's available.

>>33529409
The only reason that worked was because there's a couple of handgun cartridges that have a similar case and bullet diameter - 9x19mm para, .38 special, .357 magnum, maybe one or two others. The main thing that differs here is case length, rimmed/rimless, and operating pressure, which is something you can shoehorn into a revolver with enough engineering wizardry.

There's no way in hell that you'd be able to make something similar for rifle rounds, and there's a reason why no one has done this before: there's no actual wizards who are qualified gunsmiths.

Bottlenecked, high pressure rifle cartridges don't fit in some universal chamber size, and aside from 5.56mm being a common bullet diameter across a few rifle rounds, you're going to require a magical diameter-changing barrel to go along with your magical geometry-shifting chamber and bolt face.

>>33529473
Yeah obviously you'd be limited to a similar range of cartridges. My idea was more about adopting the same principle for a carbine with a larger mag capacity, not a magical devil-gun that can fire anything from .22 short to 40mm grenades.

Idea 1 design a 3D printable sabot round that uses 3D printable metal infused filament for the dart and a different plastic for the sabot casing and is propelled by 22lr blanks used in nail guns.

22lr nail blanks can be purchased over the counter at a lot of fun hating places like aus without the need for a gun licence. buy using a sabot setup the bullet could be designed to use over the counter pipe as the barrel while still having the high velocity property's needed to make a 22lr round useful. A round that works in over the counter pipe would help turn 3d printed guns from a novelty to a useful weapon.

>>33529758
Better off just using nails or something for the core.

>>33529766
A nail does not have the correct aerodynamics for the dart but if you embedded a nail as the core of the dart while using another plastic for the aerodynamics you could get the best of both worlds.

the idea is the bullet/barrel could be used in a bullet hose style gun like this

Actually, now that I think about it, you could just put the gas tube around the mag tube, like on a shotgun.

Should I pick up Blender or CAD to learn to make concept gun models? CAD seems to have a much larger barrier to entry.

I want to design an auto-indexing revolver that uses a gas piston to cam the cylinder rearward and cycle, so the cylinder can sit forward in a proper gas seal without needing any extra trigger action. Basically modernizing the Nagant revolver by reversing the action.

>>33529566
>Yeah obviously you'd be limited to a similar range of cartridges
Not even that. Unless the case geometry is very damn close to matching another cartridge, then you won't be able to safely fire it. The chamber must match the cartridge - otherwise you'll get case blowouts, improper seating and sealing, massive amounts of fouling, excessive throat erosion, and extremely unreliable extraction.

See this picture? This is .222 and .223 sitting next to each other. Firing .222 in a .223 chamber will blow out the shoulders and neck, maybe resulting in it getting stuck in the chamber, which can result in serious extraction problems for even a bolt action rifle.

I like the idea of a gun that'll fire a multitude of different rounds, but there's so few rounds that are even close to similar that MIGHT work in any semi-practical way. You aren't going to be able to pick up a handful of .308, .243, 7.62x39, and 6.5mm swede and toss it into the same gun. It does not work like that.

That's not even touching on the fact that recoil impulse and gas pressures can vary wildly between rifle rounds (making your hypothetical gun cycle reliably would be a nightmare), and the bolt face would need to change between them as well in order to properly extract them. Having a bolt that pushes as far into the chamber as the differing cartridges allow would also mean you'd need some way of locking it for every varying depth, so that wouldn't really work either.

Unless you want a gun that can fire, at best, two or three different cartridges - two of them unsafely - you might as well carry a couple of AR-15 uppers around with you instead.

I don't normally like to stamp down on creative ideas, but this one is just stupid, dangerous, and impossible to implement.

>>33529473
hmm...

I wonder how bad an inverted adjustable reamer would do?

With the reamer flutes being the lands, adjustable for diameter. The grooves would remain the same depth more or less without some real magic.

The main benefit of the revolver is its reliability and mechanical simplicity, not it's power.

Electronic firing introduces a lot of complexity and possibly unreliability if you have any power or contact issues.

To maintain the power while tripling capacity of, say, a 45 colt, you'd have to have a cylinder 4 inches long, and that would weigh a fuckton.

A smaller AR cartridge designed specifically for home defense and short range defense. that is still more powerful than a handgun cartridge but not as powerful as 5.56. Basically a modernized version of pic related.

I really don't understand why smaller carbines are not more widespread. They just seem so damn handy to me. Easier to use and more accurate than a pistol, less loud and powerful than a rifle. Yes a standard AR CAN be used to defend your house, but it's too damn loud.

That's a pretty decent Idea - you should cover the power rail with a rubberized coating, and tightening down the accessories forces spiked contacts through the rubber to the power rail lead under it. It would keep it water proof of done right

I'm not sure what the right cell size it, but I get the feeling the titanium would act like a fishnet and the PE would actually stop the bullet.

Alright, so I've thought of a bit of an expansion to this idea, and probably a solution in search of a problem- instead of having the forend move back and forth to cycle it, you move the whole gun back into the buttstock and out. You'd need a release somewhere to unlock it, and a spring in the stock. I'm thinking if you made this work it'd be insanely fast in the right hands, as you could use the recoil of the gun to help cycle it.

>>33534687

>>33528955
Bullet button no longer work as a loophole here in CA. Any semi-auto rifle that can accept "removable magazines" is now classified as an assault weapon. You have to re-fuck it so the mag can only be removed via opening up the receiver.

I should have said "whatever ammo is available from that range". Fair enough, my bad. Was exaggerating.

>>33540119
See above. A pistol calibre carbine is exactly what I had in mind. I never said it would be an SMG, I only said the mag would advance in a way similar to that of the bastard gun, with the mag forming the breach, as in the case of the revolver originally mentioned.

So the magazine would look similar to pic related, with each breach capable of holding one of a range of different pistol calibres, and would advance horizontally through the carbine via manual cycling. I hope that's clear enough.

A rifle with a P90 style magazine that fires 5.56. In order for the gun to not be thicker than a Glock, the magazine will be mounted on the side instead of the top. Each side will have a combination magwell/ejection port, so the only thing that needs to be done to swap sides is to swap out the bolt. I'm even thinking of ways to make it so you only need to flip the bolt 180 degrees.

That's a weak round though. Crank the pressure up to 45000 psi like the .327 and it'd be much better.

>Crank the pressure up to 45000 psi like the .327 and it'd be much better.

would it be possible to get those results without making the case to long? it still needs to fit in the gun without making the grip all weird.

i have an idea for a weapon /k/ but i want to copy right it and sell it how can one go about doing it??

>>33544441
The case length has nothing to do with its max pressure. The .32 H&R is already a bit too long for an automatic, so shorten it by a few millimeters, and ramp up the pressure.

Basically this, except for break action shotguns. It would sit right behind where the barrels tilt out but would hold 2 shells, so you just press on it and it goes right in.
I know it's retarded but still contributing to this thread.

>>33545317
Simple, but I like it. What if you went bigger, had a spring loaded speed loader thing strapped to the action that could hold 4+ rounds.

Wouldn't it be unsafe if you unlocked the stock and then the recoil kicked it back, unlocking the locking block thing too early?

always pondered the use of an electrically powered ejector for things like civilian semi-auto shotguns.

would be neat to allow for shotgun shells that might not have the gas needed to properly cycle a gas system.

but then there are other ways to get a semi-auto shotgun that can still use other methods for cycling.

Hand grenade, with a small rocket motor in the base.

You point and trigger the motor and it flies off in a more or less straight line and explodes on impact. Spin stabilized due to a spiral nozzle.

This way you don't need to have a heavy ass under slung grenade launcher on your rifle. Some space magic grenade rifle with targeting computer. Vehicle or heavy mount Mk 19. But you can still hit a target with a grenade out to some range way longer than throwing range.

For really advanced tactics you could fire it at an angle and rain fire down like mini mortars.

>Fuck your barrel life

>>33549372
That just sounds like the worst of both worlds. You get less effective grenades for the same weight you'd have with a normal hand grenade, but it still would be really inaccurate compared to something you could shoulder.

And before you say that it has some fancy targeting built in, the XM25's counter defilade 25mm grenades are WAY simpler than what you'd need and were still ridiculously expensive to develop and field.

>>33529588
Not an issue with rimfire guns, which most at the time were.

>>33549448
You add half the weight of the grenade but can get out to a target a few hundred meters away.

The problem with a dedicated grenade launcher is that it's way heavier than a slightly bigger grenade and takes up a moderate amount of volume.
The XM25 is a failure and a waste of money, too heavy, too few rounds.

No targeting just spin stabilized.

This is just a modern version of a rifle grenade only without goofy rifle attachments and grenades you can also just throw but when fired will have better accuracy.

>>33527479
A big-game-hunting-capable AR-15 with a cartridge based on .460 Weatherby brass trimmed by an inch or so to fit the standard mags; the energy should be about 70-85% of the parent cartridge, given the same bullet weight, which would put it around .458 Win Mag levels. The barrel and bolt are gonna have to be redesigned to handle the pressure, heavier profile and stronger materials, but other than that there shouldn't be any other parts that need to get swapped out. To handle the recoil, the gas port could pushed out past rifle length or the gas block could be adjustable and ticked near closed to reduce the gas pressure.

Except it'll be inaccurate as hell. Spin stabilization keeps a trajectory consistent, it's not auto aim. It only improves precision, not accuracy.

Gyroscopic stabilization works in rifles because we can line up 2 points (e.g. sight posts) and then direct the projectile down that line. Your grenade doesn't have that.

How do you even expect to launch it? Do you throw it like normal but it's rocket assisted? Or hold it out like a roman candle and let it take off from your hand?
Because either way you're only increasing the range of the projectile, and removing the already minor aerodynamic effects on precision (minor because grenades fly slowly and are heavy). You're not affecting the accuracy and the accuracy of both methods is shit.
Doesn't matter if you make a 5 MOA rifle be able to shoot 5km, its still a 5 MOA rifle.

How about a low-cost, ship- or ground-launched missile designed to provide close support to ground troops? Sorta like a Hellfire, but capable of coming out of a tube and flying 50+ miles on its own before surgically pulverizing a target.
