TechT's Hush Bolt for the Dangerous Power Fusion FX marker utilizes our "Even-Flow" venturi face technology. This "Even-Flow" face allows the Hush Bolt to obtain optimal efficiency, while quieting the sound signature of the Fusion FX 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. The FX Fusion Hush Bolt also includes a set of "soft-touch" ball detents which minimize the amount of contact with the bolt face but still keep the securely in the breach. The "soft-touch" ball detents must be installed when using the TechT FX Fusion Hush Bolt.
