TechT Hush Bolt is designed to improve the overall performance of your marker. TechT’s Hush Bolt utilizes the “Even-Flow” venturi face technology. This “Even-Flow” venture face along with our Sweeping Air Diversion Ramp allows the Hush Bolt to obtain much sought after efficiency, while quieting the sound signature of the marker significantly.
The Hush Bolt achieves better efficiency by capturing and utilizing air that is otherwise wasted. The two rearmost o-rings capture all of the air released and forces it through the bolt to fire the ball, and the front o-ring seals in the breach to ensure that the air cannot escape anywhere except down the barrel propelling the ball.
