Just saw this on Facebook...
Designed to improve every facet of the Ego11's feel and performance the DART kit increases efficiency and reduces sound signature and felt recoil as well being more gentle on paint in both the loading and the firing actions.
The DART kit enables the Ego11 to operate at consistently lower HPR and LPR pressures than has previously been possible on any Ego, but at the same time offers superior velocity consistency and efficiency.
So how did we achieve this?
DART Bolt - The Ego11 DART Bolt incorporates the latest Cure4 cushioned tip design as seen on the CSL. In addition to the Cure4 design there are now 2 seals on the body of the bolt, one either side of the transfer port. Rather than use the traditional method of stretched, incorrectly sized o-rings as the seals, the DART bolt utilizes a floating seal design. These floating seals match the internal bore of the breech to create a perfect seal, yet allow for thermal expansion and contraction of the bolt body to occur without worry of increasing frictional drag in the bolt system or loss of effective seal. The floating seals provide the optimum compromise between reliability and efficiency. They will operate with next-to-no lubrication in even the harshest conditions without any negative effects to efficiency or consistency.
Finally the new DART Bolt is fitted with a weighted insert. The small increase in mass that this insert brings to the bolt system enables the Ego11 to cycle with a lower LPR pressure at lower cyclic speeds yet still retain enough inertia to pop the exhaust valve open and overcome blowback forces during the firing phase.
DART Valve System - The Ego11 DART Valve Assembly combines an improved flow path with refined dynamics that result in significant gains in efficiency. The new design forces the valve to close off more quickly after opening, reducing air wastage after the ball has reached velocity.
The Ego11 DART Kit is designed to be used only with the Ego11 platform (Includes CSL) and is only to be used as a complete kit. Installation and use of an incomplete kit will seriously affect the performance of the marker and in extreme cases may lead to damage of the marker. Only use the DART Valve Assembly and DART Bolt together in your EGO11 or CSL Marker.

My EGO patiently awaits the new parts...
The kit out of the box.
The bolt. The first thing you notice is how much heavier it is than the cure 3 and Hush.
The soft tip.
You can clearly see the weighted insert here.
Side by side comparison. From left to right: TechT Hush Bolt, Cure3, DART.
Just the tips.
Remove macro and reg.
Remove FRM screw that holds the LPR in place.
Pull the LPR out. The valve will also fall out behind it. (not the valve pictured there)
Remove valve guide plug.
You can see the valve guide down in the slot. Take a "L" shaped allen wrench and push it out gently.
Comparison. New valve assembly on the left.
not grease the o-rings and attach the Valve to the LPR assembly with the valve guide plug hole facing down. The Larger hole on the LPR should be facing down as well.
Shove it back in and line up the plug hole and the FRM screw hole on the LPR and reinstall screws/plugs.
install the bolt pin into the DART bolt.
Bolt fits perfectly, of course.
All done! I gassed her up and she fired with no problems or leaks.
Played an 8 hour game on Saturday and it worked as advertised, smother and quieter. No FPS increase since I already had the HUSH bolt installed.
