Mechanical pre-cocking

[Stomper87]

Yup, it looks pretty similar to the second one. And I think the reason why it was "pre cocking", was because whenever I pressed the spring release, the force of the spring/piston pushed the gears slightly too far back. So when I pulled the trigger, it did a half-revolution, causing the piston to be cocked about 3/4 back. After the first shot, it continued shooting that way, kind of like an over spin. Even with my Prometheus m135 spring, it's still doing it, just not as badly.
