    So recently I learned that electricity flows better in cold metals because the atoms in the metal don't move as much creating less resistance in the conductor. My theory is that "In colder weather, AEGs should preform better in cold temperatures than in room or hot temperatures"

    You would be correct in saying that however it isn't that much of a difference.

    There probably won't be a noticeable difference but there will be some improvement.

    Not to mention the greater risk of fracturing your gearbox because it's brittle from the cold.

    The lower temperature will lower the resistance of the wiring a tiny bit, but not nearly enough to compensate for the voltage drop in the battery pack. Batteries will typically lose some voltage when they get cold, and this will have negative effect on performance. It will be more noticeable with nickel based batteries than with lithium based batteries.

    A substantial increase in electrical conductivity, to the point where resistivity drops to zero for all practical purposes, in a material does not occur until it has been supercooled to almost 0 Kelvin.

    If you're supercooling your AEG to 0 Kelvin, then something is wrong.

    Someone should acquire a tank of liquid nitrogen and do some tests. :D

    The average range of temperatures you're dealing with in airsoft isn't big enough to see anything close to a real difference, especially not once you consider the fact that, just by firing the gun, you're causing the wiring to heat up.

    Your wiring is pretty much the least heat-sensitive part of your gun. Cold is bad for your bucking, temperature changes will cause expansion and contraction in your barrel, potmetal and plastic bodies grow brittle in the cold, etc.

    The wiring in your gun, on the other hand, will gain about a 4% increase in resistance from an increase in temperature from 68f to 86f, with the difference getting smaller the higher you get. And, once again, that's only for the initial draw, the moment the electrons start to move the temperature rises in the wire.

    This thread made me happy. Thank you.

    Enough liquid nitrogen for testing would cost just as much as a PolarStar.

    Yes but it will tensify your spring
