    It's not very nice that we are moving weapon properties data all the way through weapon selection, combat component, and then this node.
    Ideally we should be able to get all this from weapon, muzzle and magazine directly.
    But ATM this is not possible, therefore it's done this way so that the values are consistent with what weapon selector is using
    to evaluate weapons and targets.
