Is it possible to zero a standard issue rifle with standard issue sights in Mars, given the reduced gravity? How?

Is it possible to zero a standard issue rifle with standard issue sights in Mars, given the reduced gravity? How?

How about the moon, not only with reduced gravity but very little drag?

I have the feeling that in the future we'll need a sight adapted to the planet we'll be shooting in, and I'm worried I'll need to spend more money than expected.

Is any company making future proof sights?

    you won't zero your gun
    the computer in your scope will

      this but more advanced
      it will just werk in every environment once you tell the scope what planet/gravity/atmosphere you have

        The scope will have a barometer and a gravity measuring device. You won't have to tell it, it'll know.

    A commonly used rule of thumb is one guard for every 50-100 people.

    If the colony is large enough, you would need armed guards. I think the XM7 would not look out of place on the surface of Mars.

        and if there isn't any xenos we will just have to create them

    We haven't even been able to land on Mars, yet you already want to go inside it? Slow down there anon. Also what is this question? You zero it the same way you do on Earth. You turn the dial. Shoot. Adjust. Then tell buddies what you got so they don't have to waste ammo.

      That doesn't work anon, because the markings are the ones that match the drop with earth gravity and drag

        So don't give a frick about the markings and just keep turning the knob until the bullets hit where you're aiming. Bullets get further away from your point of aim? Turn the knob the other way!
        Then again, if you have to be told to do this instead of mechanically following the manual then you sure as frick won't be going to Mars before they've made sights with markings and manuals specifically for Mars use.

            No, he's right. It's imperfect and I absolutely expect the US to design optics that are planetoid-specific or have adjustable holds, but picking a 50/200 or 36/300 zero and landing five or six inches high/low in that range is already standard procedure. With thinner/no atmosphere and less drag you'd see even less drop, so it would matter even less.

              You'll have a non-monotonous drops, it won't work. You can have two distances at the same marking and one in between below. Especially on the moon where you can shoot over the horizon.

                How do you accurately shoot something you can't visually see?

                It will work the same way it already does; place sight on center mass, fire, know you're going to hit within 5-6" of elevation which is good enough for combat accuracy.
                >You can have two distances at the same marking and one in between below.
                What? The impacts in between your zeros are above, not below. Picrel. Don't lecture me on physics when you're literally inverting a parabola.

    In practical terms you do it in exactly the same way as you would on Earth. Pick a range, shoot at that range, dial in the sight so it is at the spot the bullets keep hitting.
    Now with no gravity the bullet will no longer follow a parabolic path, but a straight one. This means you can no longer have the bullet's path and the line of sight intersecting twice, they'll just intersect once instead, at the range which you've zeroed for. Closer than this you need to aim above where you want the bullet to go, further out you need to aim lower. Or you just zero for infinity, ie you make the sight line and bullet's path parallel, and always aim an equal distance above where the bullet's supposed to go.

      mars and the moon both have enough gravity to not make it infinite
      fun fact, you can shoot way way over the horizon on the moon

        Could be, I gave generalized advice instead of celestial body-specific because I don't know how exactly it'll play out here or there.
        Though that said, whether or not it's actually infinite isn't what matters, it's whether or not there's significant bullet drop within the ranges you have any hope of hitting shit at that does. If you're trying to hit something a mile away with a 2 MOA rifle then whether you have no bullet drop or an inch of bullet drop isn't going to be terribly important to you.

          won't we just have perfect smooth bore barrels?
