TECHT's Hush Pro Series Bolt for the EMPIRE RESURRECTION paintball marker utilises our "Even-Flow" venturi face technology. This "Even-Flow" face allows the Hush Bolt to obtain optimal efficiency, while significantly quieting the traditional sound signature associated with the Resurrection. The Hush Bolt is not only quieter, it is also lighter and smoother! The HUSH Bolt is made from 900 SP Series Delrin which makes it cycle smoother and has lower wear and friction properties. 900 SP Series Delrin makes the Hush Bolt ever! TECHT opted for this new material because it has much better wear resistance than standard delrin. This means your bolt will maintain optimal performance much longer than other bolts, and won't scratch as easily. Take your marker to the next step in performance!
