Guns in space

That'd be a complex ass system lol

small arms use in EVA would be impractical. unless you can use magnet boots on a metal surface with enough mass that the velocity of the bullet would not affect it too badly.

But as far as I know modern astronauts don't use magnet boots in any capacity. Seems like only a sci-fi concept as of now.

Considering even basic electronics in space rely on some form of radiator to reject heat, as there's no atmosphere to convect/conduct it away, you'd absolutely need a similar system on a firearm.

1atm is not a lot of pressure compared to the pressure of the gas inside. .22LR is rated to 24,000 psi . 1atm is only 14.7psi. Round to round is going to vary more than that.
Maybe gas trap might notice a difference, maybe, but normal gas operation won't.
All guns have their own oxidizer. That's what the Saltpeter in classic black powder is for.

We watercooling again boys.

The retarded block magazine gun would actually be useful in space. The block would absorb most of the heat and could be discarded.

1. There is gravity. Not as much as down here on a planet say, but a shit load more then the empty spaces between galaxies.

2. There is also inertia. Without macro gravity the bullet isn't going to slow down much worth thinking of until it actually hits something. Even if that takes years or centuries.

But there's oxygen underwater, fish have gills for a reason.

Just wait until the first ND on a spaceship/space station.

SAFER, the current smaller/simplified MMU used on all EVAs nowadays, can already arrest basically any spin automatically. You could literally just use it as is.

"Space" is actually a scale between unimaginably cold and mind bending hot. The troupe of people instantly freeze drying when thrown out the airlock is not 100% accurate in all circumstances. Sometimes they'd pop like they where in a microwave.

It's also worth noting that the lack of any kind of medium to transfer that heat other than radiation makes temperature measurement in space somewhat misleading for the average person.

If there is ever some kind of space station open to the public and thus requiring some formed of armed security, they'll probably have special bullets like air marshals use to prevent hull breach every time they actually have to use them.

It's not accurate in any circumstances. That's just not how a vaccuum works.

You're not thinking hard enough user. Fill the shroud with water and hook it up to a PC watercooler, duh.

Would the explosion in the gun cause the how spaceship to explode due to the high amount of oxygen?

you think spaceniggers breath 100% oxygen in space?

Electronics are a lot more thermally sensitive than a rifle. They need to stay much cooler which is a hell of a lot harder. You only need 6.25% as much radiator area to keep something in space at 600K than you do to keep it at 300K.
Meanwhile dumping all your ammo will get you up to almost 1000K at which point you're radiating 124x as much heat as the 300K object.
The Lewis is forced AIR cooled user...

This is a good starting point on the subject:
assets.documentcloud.org/documents/3038458/The-Meanderings-of-a-Weapon-Oriented-Mind-When.pdf

Not 100% but it’s higher than earth I think and it’s pressurized.

Wouldn't all you'd need is a slingshot?

Earth is slightly above 20%, and I’d imagine space stations are the same or slightly above or below.

No no no, no trying to save face. You never said anything about conversion and filling the finned shroud with water is not better than just using a from scratch water cooled gun. You dun goofed and posted the wrong gun. That's alright m8, happens to us all.
That said I'm not sure water cooling would even work like it does here. With no gravity, the steam doesn't escape and all you've done is made a big thermal mass with inconsistent transfer. You're not actually voiding heat any better without adding a pump and radiator and complicating the system. At that point just make it a big tank of wax like the LRV.
Kek it's an increased fire risk but it's not quite that dangerous. All the apollo missions and every EVA we've done have been pure O2. In space, it's only at 1/3 of an atm. Apollo 1 before the fire was at 1.15atm.
Nah the ISS is sea level pressure, mixed gas. All space suits and a bunch of past missions have been pure O2 though. It has its pros and cons.

You could completely counteract the momentum of every round of non-linked ammo carried by an entire infantry squad with a single MMU.
With 3, you could do the same for every single round carried by all 9 men.
Unless you're giving spaceborne infantry a significantly larger loadout than ground troops for some reason, MMUs, aggressive muzzle brakes, and holding onto/bracing against/pushing off your surroundings will be more than adequate.

Why are we having this thread once or twice a week all of the sudden?

Just a fad. This particular one repeats every so often. Same thing happened when Space Force was first announced.
Probably started this time because of those Boundary shillposts.

Space force thread is fine, but having the same retarded questions answered every week is too much. There should be a good screencap or pasta.

Fucking oath. Sometimes there's cool discussions in these threads, so i keep reading them but there's always the same bullshit.

And its always-fun opposite
>Balanced Recoil eliminates recoil/won't push you
I'm sure I've missed some but god those have to get corrected every thread. Usually multiple times. Its worse than caseless threads were someone will, without fail, bring up "no ejection port" as a pro and "overheating" as a con.
Worst part? Space infantry is the least relevant part of space combat. Why not threads about Mars as a battlefield or the Moon? If you're going to have to deal with retards anyway, at least have some variety.

russians are only consuming ussr heritage and make nothing new. say hello rogozin.

>yfw you realize that all rifle sights won't work on Mars because the gravity is different

A lot of them will be fine because your point blank range will also be 3x longer. For a lot of them that's about their ideal useful range anyway. Higher magnification scopes will need something though.

The Perfect Space Rifle is as follows, prove me wrong.
>polymer cased telescoped ammo - lighter to save money on launch and dV in space while also running cooler than brass and being more cookoff resistant
>AUG style hand guard to fit bulky space gloves
>AK style safety/selector lever for same reason
>belt fed for minimum reloading during EVA
>constant recoil for easiest thruster compensation and bracing
>progressive twist and polygonal rifling for for most even barrel wear while hot (I.e. always)
> can you chrome line poly barrels?
> reversible asymmetric muzzle brake - slightly more on one side to help prevent spin from shouldered rifle being off axis. Flipable for lefties.
>relatively high muzzle pressure to better use brake
>red dot because paralax is a bitch with no repeatable cheekweld
>nonmetallic frangibles and suppressor capable for nonEVA combat

>Bullpup
Space environments will not make them any less shit than they are now.

switch out the lubricant for dry, non-graphite lubricant and you are good to go.

That's a good idea. It could be like the guns in mass effect. Ejecting the magazine cools the gun.

Earth's orbit is alway filled with bullets. Debris flying at 8000 meters per second compared to a bullet at 3000 feet per second.

I didn't say bullpup. Pic was just was an example of the hand guard.
Besides that one PKP variant how many bullpup belt feds are there anyway?

Assuming that the gun would only be used in space, wouldn't you want it to be as heavy as possible to help reduce the amount of push the recoil has? Something like a hotchkiss chambered in something like .223

Something like this?

The entire principle of gunpowder creating explosions to propel something requires a fast reaction in a small space, a reaction far too fast and far too enclosed to work without an oxidizing agent. All ammunition for guns EVER used self-oxidizing reactions.
