The Hush Bolt is not only quieter, 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 other words, its the best ego bolt you can buy.
