Post the idiotic ideas you have for weapons that you would make if you had either the skill, time or money.
For me I would make a double barreled Sola pistol like those retarded AF2011-a1 pistols. I would call it the Sola
angel because it would kind of look like it had wings when it was firing.
Pic related but with 2 barrels.

A Mini M1 Garand, Pedersen, M1903, M1917, SMLE, Gew98, M39, M1941 in 30 Carbine
I want to make a HMG with a centrifugal stabilizer
my idea was to have a golf ball in a gas system, so that hot gasses cause it to spin in the system when the gun is fired
I think it would change the recoil characteristics enormously, the gun would "pull" a lot more, and jerk a lot less
I see it as also usefull for weapons with specialized gas systems, like low gravity or underwater
The most compact shoulder-able rifle possible. I mean the smallest thing you can physically shoulder and hold with both hands. The ergonomics would have to be like this pic. Right hand on the angled grip, left hand on the horizontal grip. The grip has to be angled like that so that you're not forcing your wrist to turn. It'd be like holding a megaphone.
You might need a suppressor or face shield if it's in anything bigger than pistol caliber.

AR-15 with a folding stock.
My idea will totally fucking work, too. I was called a retard and told to learn engineering, but fuck them, I can do it. I figured it out. Let me draw some things up and prove it.

>>28035682
I always wanted to buy a cheap shotgun/bolt action and chop down the barrel and put a pistol grip on it. Horribly illegal, but a 12 gauge SxS pistol or a bolt action pistol would amuse me to no end.
>>28036265
it already exists anon.
AR 15 with folding stock idea. This shit will work.
>>28036301
Not a retractable stock, but a folding stock. Same feel as shooting an AR. just with a folding stock.
>>28036301
Just googled it. How does it fire without the bolt flying out and hitting you in your speak hole?
My idea (>>28036320) lets you fire whether the stock is folded or not.
>>28036320
That....Has a few flaws, but that's actually pretty fucking cool.
>>28036329
>AR with folding stock
So an LR-300? Haven't you played stalker anon?
A gun with a spinning barrel.
Just one barrel attached to a motor, making it rotate.
Not sure how much that will fuck up the trajectory but I want to see
>>28036412
Any physics/engineering/intelligent guys here know what this would do?
I'm genuinely curious
>>28036434
in the opposite direction of the rifling or the same direction?
>>28036447
Same direction.
Opposite would just cause the bullet to spin less, if any at all right?
>>28036462
>Opposite would spin less
I assume so, or depending on spin speed would make it twist the opposite way. As far as the same direction goes, it would probably give it the equivalent of a higher twist rate I imagine. So like, not the much difference, as too high twist rate tends to not be a bad thing.
>>28036485
assuming the barrel is rotating relative to the bullet
>>28036367
I was thinking it may work better if there was a buffer tube on the other side too. Pretty sure that'd work too.
Actually, this gives me an idea for a bullpup AR.
>>28036390

Sorry senpai already exists.
http://www.lawtactical.com/ar_folding_stock_adapter_gen_3_m_p/99312.htm
>>28036412
I was trying to think how this would work.
What I came up with:
You would have to have a free floating, lubricated barrel (black cylinder) inside the actual barrel (gray cylinder).
You would have to have magnets (blue) rotating to cause the black barrel to rotate.
The red cylinder is the actual bore through which the bullet would travel.
>>28036499
look up the lr-300.
>>28036320
its been done
>>28036198
Don't you mean 7.62x25??
>>28036545
I guess you could have a little friction wheel motor rotating the inside barrel too.
I'd make striker-fired da/sa machine pistol system, which could fire 5.7x28; 4.6x30; 9mm; and some new crazy caseless calibre bullets both on the ground and underwater, and could handle dust and dirt stuff very easily; and would also come with big barrel which could be sawed off when needed (so that it could be bought in countries such as Russia).
That's the gun of my wet dreams.
I actually reflected the idea of attempting to do engineering stuff a bit.
>>28035682
A three barrel bolt action rifle, where all three rounds are chambered with one cycle of the action.
I had a dream where the concept came to me, but the closest thing I've seen to it so far is double barrel bolt action. Three barrels might just be ridiculous.
>>28036542
>>28036553
Well then, fuck folding stocks. Bullpup AR FTW
>>28036107
That's the shortest action. Give it an 8 inch barrel and that's what I'm talking about
>>28036673

Bullpup rifle that ejects from the bottom beside of an off centered magazine (like a bren, but in the bottom). It would have an ambidextrous charging handle, and just for the lulz a safe action trigger.

I want a mash up of the clover leaf revolver (pic related) and the fitz special: https://en.wikipedia.org/wiki/FitzGerald_Special
A four round revolver chambered in .44 special with a 2.5" barrel, bobbed hammer, and cut down trigger guard. I want it in stainless steel, no rear sight, and a gold bead front sight. I want rounded smooth grips made of high grade African ebony.
I want custom made Safariland speedloaders to go with it.
>>28037461
This is so specific that I want to make this for you.
I could make the grips (woodworker for ten years), but not the gun.
>>28036232
>CHUNNNNG
>>28037461
>>28037480
I didn't specify, but unlike the original cloverleaf, I'd want this in double action. Any idea how much it would cost to get a manufacturer to make a one-off gun like this?
>>28037461
look at the clover leaf revolver, it does not have a trigger guard.
A recoil operated 5.56 that uses AR lowers. Piston ARs are popular, so why not recoil operated?
>>28037591
You are absolutely right. The only feature I was referring to was the capacity. In re-reading my post, I should've simply said "four round revolver" with no mention of the old cloverleaf.
A blowback 308 pistol.

a revolver in .46 magnum with the express purpose of having a suppressor compatible revolver
Fully automatic rifle that shoots miniaturized HEAT rounds for anti-vehicle purposes
Basically the keltec rdb but I for some reason I thought the ejection port would go in front of the magazine well instead of behind it.
>>28037678
So a M2 with Raufoss?
>>28037633
Yeah, unless you mistyped .380, you're gonna have fun with that. Someone smarter than me did the math, and a straight blowback .308 Winchester would require an 11-pound bolt.
My insane idea? For some inexplicable reason, I find ultra-long-range shooting intriguing, so my thought is something to make that a little more...interesting. Take a 20mm or 14.5mm, using a smoothbore long barrel with extremely slow-burning powder, firing a subcaliber discarding-sabot slug made of osmium-iridium alloy, with as high a ballistic coefficient as possible.
>>28037584
the biggest issue is the travel distance of the cylinder. You would need a long and hard trigger pull for it to work, I'm talking Nagant level or above trigger.
>>28037687
>search Raufoss
>penis becomes 200% erect
>>28037584
I'd assume a few thousand. I don't know, though.
You could probably mill most of the parts yourself.
>>28036545
Make a naval gun's barrel rotate fast enough and you can give it any spin you want.
No more fucking with rifling on massive barrels, right?
>>28037690
>extremely slow-burning powder
How about black powder?
>>28037699
I see no reason why that'd be; not saying you're wrong, but rather I'm ignorant. Can you explain?
>>28037721
>attach gun barrel to center of windmill
>>28037737
I realize it would only be mildly useful if you wanted to fire different weights and lengths of projectiles from the same barrel, but still.
>>28037725
with a normal revolver you have all of the rounds relatively close to each other, but if you have 4 shots the way the angles work out there would have to be a 90 degree angle between chambers which makes the double action much more difficult to make.
>>28037757
Oh! Now it seems obvious.
>>28037719
If I had the knowledge and the tools.
>>28037724
Except anon, black powder burns far faster than most smokeless powders. Black powder is an explosive. https://www.youtube.com/watch?v=tTAKr3Y2EV0
>>28037781
smokeless when confined in a gun barrel should "detonate" to my knowledge, instead of a super slow burn.
A combination AK-57 Uzi radar laser triple barrel double scoped heat seeking shotgun.
>>28037789
Nope. Detonation blows up guns, powder charges burn, albeit at very high pressure and quickly by any timescale you can actually perceive. A low-velocity explosive like ANFO runs at 3200m/s (or about 10,000fps) when detonating, C4 goes at more like 26,500 ft/s.
>>28037789
and that is not what you want. You want a slow even burn to get the highest achievable speeds.

A gun that uses gasoline or diesel as propellant.
A rifle that is the shape and size of a 3ft 2x4 that fires a modern day 50-70 cartridge in matte black
The sights are tritium pistol sights that also have a flip up for range and wind adjustment but fold into the upper of the gun so that the whole thing will just look like a matte black steel 3ft 2x4. It'd have to look inconspicuous enough though that I could keep it in the corner behind my front door and nobody would even give it a second passing glance.
It'd be my home defense rilfe

You could always get a 2x4 and drop an existing rifle into it. Just resaw the 2x4 in half, route (or drill) out a cavity for the barrel and reciever, glue it back together, then route/drill out cavities for the sights.
>>28038074
Sort of, yeah. But I'd have to make the ammo myself and I'd like the rifle in the bullpup design with only the tiniest little slender trigger sticking out the bottom of the rifle. No trigger guard at all and a rubberized business plate because 50-70 government in a modern cartridge with modern powder would have an assload of recoil. The cartridge being in a 86-120gr range depending on the loads I'd be firing
rifle that uses a helical magazine filled with caseless ammo
Make ammo specifically for the Taurus Raging Judge (the one that shoots .454 Casull)
First one will be captive-piston ammo, like what the Russians had in the Cold War and like the US's QSPR. The large bore and long cartridges will give the piston extra travel and room for gas to expand.
Second ammo would be gyro jet ammo. Looong rocket ammo. I can be rocket-only like the original or it can be boosted with a regular powder charge.
>>28038321
shit, while I'm at it, make a new gun just for this. Use a 6 o'clock barrel but with a simple hammer group like the OTs-38. Less ugly of course, looks should be more like the the Chiappa Rhino.

Do not reject the divine inspiration of the /k/ube
A revolver with a 10 inch barrel situated at the 6-o-clock position of an eight-round cylinder, which would be top swing. Cylinder gap closing mechanism to reduce fireball. Built to fire .500 magnum.
You'd either need the arm of a god to fire it accurately, or have a robot arm instead.
A top break revolver that has a gas seal similar to a nagant, but in .22lr or .45ACP.
To use conventional brass. the cylinder would have to be cut short. The bullets and maybe 1/10th of an inch of casing would be "sticking out" of the cylinder, and would move forwards. When cocked, it'd be a full chamber, but half would be on the cylinder and half on the barrel.
It's super retarded but it'd be awesome.
Or, since double action would require retard strength, use a lever-action type of lever to cock it. A top break revolving mares leg with a gas seal. Perfect for suppressed stupidity.
>>28035682
>sideways Luger
How the fuck is that a bad idea? I love it, and now I want one...
Would make a revolver designed to fire caseless flechettes. If you stick the primer onto the back end of the flechette, I'm certain it could be done.
Also make an airburst rocket propelled munition. Something the size of a LAW.
Also, a rotary mag on a .308 so you could machine it to be cheap and accurate.
>>28041764
>rotary mag on .308
It's been done. Steyr SSG 69 (generally considered an excellent rifle) and some versions of the Savage Model 99. Rotary mags aren't cheap to make, though, and tend to be limiting in terms of what loads you can use in them.
>>28038321
One more idea with this- make replaceable sub-caliber pepperbox cylinders. Then you can swap cylinders to shoot 9mm, .22, and other smaller rounds. It'll have poop ballistics since the bullets just pass through the barrel but it'd work.
>>28038835
>>28038859
I imagine with telescoped caseless ammo, having the magazine feed and index like the SRM16 or X-rail would work best.
>>28038321

How about a spinning smoothbore barrel, that's slightly subcaliber, so that the bullet has some friction as it's travelling down the barrel? I mean it's a lot easier to make a perfect smooth bore barrel than perfect rifling. Add an inertial wheel to the barrel so it adds a lot of stability to the gun and it might be highly accurate.
I want a wh40k style bolter pistol/rifle.
By which I mean some kind of new low velocity high mass un-necked cartridge, like a giant 45 (in terms of appearance and functional principal; big ass heavy subsonic in a relatively short case), like a 80 or 90cal

Single shot rifle with automatic shell ejection like most artillery pieces. Just because.
Revolver rifle that has tube magazine in the buttstock.
So imagine Colt SAA. The magazine feeds new rounds in to the cylinder on the left side of the frame and the gun ejects empty brass from the normal ejection port on the right. Ejector would be built into the frame. Maybe cylinder could have a camming groove so the rotation of the cylinder operates the ejector. Naturally the original ejection rod would be useless for this. Maybe it could remain in place to clear stuck cases. I'm amazed if this has never bin dun befo.
