Got some more guns I worked up.
Did some reading into railguns and came up with my own little ideas. Built them around the current bases of weapons to give them a realistic feel/size. The rifle is built around a AWP sniper and the other just around a normal small pistol. Open sides help reduce the heat problems. Friction is also a problem with them, so theoretically, I thought if you had rotating magnets you could essentially have the projectile hover in the middle, thus the rails dont wear out. Its a bit of a wishy washy idea though.
It would make for an interesting weapon though, game-wise. You have to spin up the magnets and then the ideas of reloading both battery and ammo. Railguns are interesting too because you don't need gunpowder when firing so you can have way more bullets in a magazine. Or potentially have larger calibre rounds in smaller guns. It would depend on how strong a force the magnets could produce though. From current science I dont think it works at all on a small weapon size. They've only been able to experiment with really big calibre stuff. Also painted up that flying fortress thing.
