>>7840770The Ultra One relies on the solid dart to tell whether or not it’s loaded. At the front of the pusher arm is a small, spring loaded tab. Contained within the shell is a small catch that stops the forward movement of the pusher arm. If an Ultra dart is loaded, this spring-loaded tab will disengage the catch, letting the user finish the trigger movement and push the dart into the flywheels.
You only need to remove the lock. Presto, instant no-DRM Ultra.
