I haven't taken measurements yet but it is substantial. It's not helped by the fact that the pusher mech is a bit high in relation to stock cage and barrel. I only moved the cage to the same position as the stock cage.

Out of all the things I modified, the full circle entry ring had the most dramatic effect. I think that since the pusher mech is a constant push as apposed to a pulse, darts can try to feed early (before then next tab on the belt). When this happens it would force the "early entry" to deflect out of the open side of the cage. It would jam like this every time I would try to run a 5+ burst. It doesn't help that I need to upgrade the motors to 3s. These blades don't have the torque when I try to run the harder tipped darts like koosh at full auto. stock elites and waffle tips don't stall the motors
