Oh, and protip: the magnetic coils in a gauss gun need to get exponentially further apart in order to impart more acceleration onto the slug. After a certain point, evenly-spaced rings becomes inefficient because most of them aren't really doing anything to the projectile. You should use many smaller coils rather than a few large ones.
I take it you are learning that you can't just make up a gun now, yes? Effort must be put into the design or nobody will look twice.
E: Also, the way that bar is shaped and where it's attached mean that it is doing literally no reinforcing at all, nor is it alleviating any stress from the gun's own weight.
