raycast spawn problem

Hello, I'm working on a game project in school with a couple of classmates. I'm making a gun script for our FPS shooter and I have encountered a problem. The problem is when I'm shooting my raycast casting points get's further and further down for every shot and I don't know why. The raypoint don't move (The object where I start my raycast from). Any one that has any idea what the problem may be? I have pasted my code in the post.

Thanks in advance.
