Quote HistoryQuoted:
For weightless and vacuum infantry warfighting, handheld lasers are the key. No recoil, which most projectile weapons will have an will cause all kinds of problems in a weightless environment. The laser doesn't have to be very strong, just strong enough to put a hole in the enemy infantry suit; at that point the vacuum would stop or kill them. In a weightless environment, the technology has probably advanced to the point where a single man could carry the weight currently required for laser weapons. Weapon of choice would be some type of automatic shotgun loaded with high velocity flechette rounds. I imagine that hitting an enemy that is jet packing around would be very difficult, and a cone of death > a fine stream if death. |

It will be awesome to magdump and watch as your upper receiver melts into a slag pile. No atmosphere, no heat dissipation. Radiators might help a bit (maybe an extra 5 rounds), but you would need some type of active cooling on any high heat chemical reaction in space.

Well, maybe by 2017A4 we can cobble up something...oh, wait, that was last year. Ok, maybe we could invent some sort of liquid cooling system by...2117? But only if weight can somehow be minimized. |

The ISS has to keep the temps habitable for humans. And has to dispose of vast amounts of solar heat, when in the sunlight.
No humans have to live in a barrel of a rifle, and the temps will decrease in cauchy sequence. Faster when hotter and gradually slower as the differential changes. |

That's just over a minute. With a suppressor, which will if anything, increase the heat retention.
I don't think heat is even in the top ten issues of designing a space rifle. |

Lots are missing the mark. You don't really need a rifle for use actually out in the vacuum of space. That doesn't make sense. What you do want are personal defense weapons for use on board ships and inside of planetary habitats that have controlled atmospheres. Sort of like naval combat. Sailors aren't out swimming around shooting at each other with rifles. Sailors are on big ass ships that have their own ship borne guns. But ours is gonna be forging through the air lock in the vacuum closing with and destroying enemy cosmonauts.

1. Make sure you zero your weapon to infinity because there is no bullet drop.
2. Will need an overly aggressive compensator or as suggested earlier, a suppressor. Gas coming out the barrel will be disruptive to the AO if in the confines of a ship. Recoilless rifle might be an option since weight is not a factor. 3. Why not attach the weapon to your arm and instead of a scope, use a mini camera with as a sighting device. Output is small vid screen in helmet or eyepiece. Your eye doesn't have to mate up to the weapon. 4. When all is said and done, for CQ combat a squirt gun with acid might do the trick better than an AR.

You'd probably want something liquid-cooled since there is no air to cool the gun in a vacuum, there is only radiation, which won't cool the gun quickly enough. Would have to use something that stays liquid at very cold temps. |
