Main Military Weapon of Your Country. MMW A10

[Triplebaconation]

Bullpup, overgassed long-stroke piston equipped with BARS, fitted with a mid-eject system. Manufactured with relatively loose tolerances, and a reciprocating charging handle. Firing a .338, 300 grain subsonic AP bullet.

Penetration seems a bit low, with all sorts of ceramal, nanostuctured polycarbonates, impact hardening fluids and such armor technologies in sight.
Energy increase might be necessary, but in that case BARS might not cut it, imgine weighing three times less, and Martian people are likely to be higher due to the low gravity, meaning more leverage.
My fault for not dating the project it'd be around 2120 or such.
Ejection at all might be problematic since dust can be kicked up by steps, cartridges etc.
It would be able to function for some time,but not too much, simulated Martian dust got into spacesuits as well.I'd go for a caseless solution, or perhaps gyrojet.
Could some sort of gyrojet work?

Recoil doesn't have anything to do with weight.

is of much sex.

[Ares Ascendancy]

Middle East sand is worse from what i can tell. M16s and AKs work fine in that.

It got into stuff that was supposed to be airtight. I think its hard to über,but I believe it is about equal practically speaking.

It has,practically speaking. Recoil won't increase, the effect of it on you if you weigh barely more than the third and remain the same height, will increase.

Um, wut. Recoil has everything to do with weight.

Recoil is the felt rearward acceleration of the gun, as a reaction to the force propelling the bullet forward. Now. that force first has to act upon the gun before the gun actually begins to have noticeable recoil.

Meaning, the more your gun weighs, the more force has to be exerted by the bullet in order to overcome the tendency for objects (the rifle) to stay at rest.

Physics is awesome.

Heavy 8.58-9mm bullets are very good at penetrating armor. And you can load it with a saboted APFSDS round for extra lulz.
Increased energy shouldn't be necessary.
By then you should be using railguns or guided HE airburst munitions.
Not really. With loose tolerances and the action described, dust will be irrelevant.
Gyrojets were notoriously vulnerable to dirt. I imagine mars would be hell on them.

I swear they increase the weight of guns to soak up heavy recoil.

Knowing dtn, he's probably splitting silly hairs as regards actual recoil force and felt recoil/muzzle flip, etc. It's pedantic and irrelevant. I suggest you don't bother with him.

...which is basically what he said.

You are again not completely right,but you are near to it. You speak about mass. Mass is a bit more important factor than weight. Mass is the tendency to stay at rest. Weight is the force whit which the object is dragged down by gravity. An object of 5kg mass weighs 50 newtons at 1 g. It would weigh about 18,5 newtons on mars with its 0.376g.

Urrrp. Thanks. I keep forgetting that there's a difference between mass and weight.

Damn you, gravity, y u b different everywhere?

Why were gyrojets vulnerable to dust? Gyrojets were designed in the 50ies, if I recall correctly. Maybe this issue can be sorted out.

Also with the recoil problem, you have not taken account the soldiers on mars will most likely be robots, and have thrusters attached to them to help them manuever around easier, they could either be too heavy to be blown back, which is unlikely because it would be really expensive to get them into space, or they would counter them being pushed backwards with the mini thrusters.

They might even use laser weaponry, as the russians were developing, but cancelled, a pistol which used flash bulbs to project a laser, rupturing enemy astronauts suits and messing with enemy cameras nd sensors etc.

Easy to make this mistake in English, this distinction being so rarely used in regular speech.

Dust kills lasers, so they are not the ideal martian weapon even if powerful. But my country will use them to some degree later on. Now we are talking about early colonization era c. 2120. No industrial potential for mechs, and suits are easy to reinforce against weak lasers. As well as no capacitor technology for handheld lasers much above a kilojoule. With dust and ablative protection thats not so much.

The pressure generated by a gyrojet requires a ventilated barrel. This allows shit to get into the mechanism, and generally produce large quantities of anti-lulz.

Pre-acelaration, by an electorthermal mechanism/good ole explosive propellant, could counter that easily. The rocket would engage after it is about 20 cms from the barrel, thus a solid barrel will suffice.

Gyrojets also had lulzy low velocity inside of ~30 meters, and lulzy low accuracy past ~30 meters.
