It utilizes high-grade carbon fiber construction which is superior to the aluminum typically used because it does not expand as much from the heat of the sun, thus maintaining POI better. It also adds rigidity and is better suited to controlling harmonics than aluminum. De-resonating rings have been added to the base of the shroud, and these press on the barrel to help dampen vibrations.

The rotating weight at the end of the shroud can be adjusted in small increments that noticeably affect the performance of the air rifle, and the weight can be set without the use of tools, and is designed to maintain its setting without tools as well. The tuner comes with three ends customized for different calibers: .177.22, .25, and .30. These ends are engineered to improve accuracy and are also threaded to let shooters add a moderator.
