TechT's Hush Bolt for the Planet Eclipse Ego and Etek marker series utilizes our new "Even-Flow" venturi face technology. This new "Even-Flow" face allows the Hush Bolt to obtain optimal effeicency, while quieting the traditional sound signature associated with the Ego and Etek significantly.The Hush Bolt is not only quiter, it is lighter and stronger! The HUSH Bolt is made from a new space-age polymer called Ertalyte TX, rather than the traditional delrin. Ertalyte TX is the newest, latest and greatest polymer that the best paintball products are being made from. TechT opted for this new material because it's stronger and has much better wear resistance than standard delrin. This means your bolt will maintain optimal performance much longer than other bolts, and not scratch near as easily. The Hush Bolt also pushes the limits of weight reduction while not compromising the velocity limits of the stock rammer. In otherwords, its the best ego bolt you can buy.Other bolt features include our ramping detents grooves which make for a much easier transistion for the ball detents during each shot. The detents no longer get hung up on the face orings on the bolt return. We also added the perfect angled ramp to the face of the bolt that prevents ball clipping (chopping) and also gently pushes the ball detents down on the forward bolt stroke. All in all, we designed this bolt to perfection. The result is a bolt that is the quietest, most air efficient, most durable, and softest on the detents and balls.Quiet Operation- the Hush Bolt was designed to have a less abrupt "pop" or "crack" that has traditionally been associated with Ego Markers. The TechT Hush Bolt has a quieter, more muffled sound signature. This means your field position is given away less, and communication on the field becomes easier than ever before.Increased Efficiency- the combination of the Even-Flow face and our unique o-ring configuration allows the Hush Bolt to seal the routing of air directly through the face. This results in less air being leaked around the bolt itself- which means far less wasted air. The Even-Flo Face also allows for extremly unform airflow- this means tighter groupings and better accuracy.Super Light Design- the Hush Bolt weighs in at only grams 15.5 Grams!(o-ringed/ without the pin)100% Ertalyte TX construction means you are getting the lightest, fastest bolt possible. The use of Ertalyte TX allows for a less porous, more durable surfacethan standard delrin. Ertalyte TX is stronger and has a better wear life than standard delrin.Radial Ramping Face- our Hush Bolt features a Radial Ramping Face which allows for less ball stack clipping, which means less broken paint in your breech.R.A.D.- Our Ramp Assisted Detent groove allows for much smoother operation, and prolongs the life of your ball detents.
