TechT's Hush Bolt for Azodin Markers utilizes our new "Even-Flow" venturi face technology. This new "Even-Flow" face allows the Hush Bolt to obtain optimal efficiency, while also quieting the sound signature. The Azodin Hush Bolt is also much lighter which aids in reducing kick when firing the marker. Other bolt features include our ramping detents grooves which make for a much easier transition 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.
