This is how Edwins Ram Assist Spring helps, and what it actually does:
Operation: the spring is an assist spring, which means it has a light force. Furthermore, the hammer will not be forward when you air-up your Tribal. When you fire your marker the noid directs LP air to the ram which pushed the hammer to the valve, when you let off the trigger, the noid re-directs air to the ram and pulls it back. So the spring will be compressed by the noid and the ram. Just like when you air up your marker your ram/bolt moves to the rear (open bolt) the spring will compress at that time, and when you fire it will assist the hammer to go forward. The assist is needed (or desired) because there is two types of friction on the ram, static (not moving) and dynamic (moving). The static friction is higher so sometime rams have a hard time getting started with its forward motion. The spring assists helps break this static friction, and enable the hammer to hit the valve at a more consistant force. Static friction changes with time and other variable. That is why it is called FSDO, once you get the ram moving the static friction has less time to "setup" so the first ball drops off....with the spring the first shot doesn't drop off because the spring breaks the static friction.
Hope this answered a some questions.
