That small allen wrench that came with the package.. get it. Now, to adjust it, look in the magwell in the tiny space above where the mag goes. Shine a flashlight down in that area, and you will see a tiny screw. Screw it in to hop up, and unscrew the screw to hop down.
Also, a crack in the seal won't be the problem for this. That would only decrease FPS.
