Post upgrade G&G M4 gearbox lockup

I just upgraded my stock G&G Combat Machine 16 Raider with a Matrix M115 spring. When I fired it, the gun barely cycled the first time and locked up the second time. As I was taking out the stock bolt, I heard a click, like something had released, so I test fired it again. It fired multiple times but sounded a little rough. Every time I tighten the stock bolt down all the way it won't fire and when I unsrew it a little bit, it will fire. Any hints?
