Now, if you take a railgun and replace the fatman's launching mechanism with it... You'd have a weapon that far surpass a metal gear's ability to launch nukes... Sure in theory the metal gear can launch a nuke from anywhere, but it's a big heap of metal compared to a portable sniping nuke gun. No a railgun has a very different effect than a cannon... and I guess you are right about the scope, didn't think about the render distance
