The Zero Pseudo-Integrated Sound Moderator is an efficient muzzle device designed to reduce acoustic signature and conceal the shooter's position. The design features an 80 mm overlap over the barrel, balancing the overall length and weight of the rifle while maintaining internal volume for effective powder gas expansion. The device reduces sound pressure by 30 decibels, making shooting more comfortable for the ears and minimizing the visible muzzle flash.

Commentary / Comments
The key structural advantage of the Zero model is the combination of an aluminum outer shell with a stainless steel internal core. This solution withstands high thermal and gas loads in the primary expansion zone without baffle erosion, keeping the total weight at just 330 grams. The 80 mm barrel overlap shifts the weight distribution backward, preventing muzzle-heavy balance and ensuring comfortable handling and quick target transitions.

The device is engineered for popular military and hunting calibers, and the wide range of available thread pitches allows matching it with most common platforms. It is essential to strictly follow the installation manual and check thread tightness before each deployment to prevent shift during firing.

Target Audience / Suitable For
Military personnel using rifles in operational environments benefit from a 30 dB sound pressure reduction and flash suppression, significantly reducing position disclosure during firing. The pseudo-integrated design adds only 150 mm to the rifle, preserving maneuverability for operations in confined spaces, vehicles, or indoor environments. The combination of a steel core and aluminum body ensures long service life under intensive use.

Hunters and sport shooters seeking to protect their hearing and mitigate recoil and muzzle rise can use this sound moderator for comfortable medium- and long-range shooting without bulky, heavy attachments. The Cerakote coating protects the unit against moisture and dirt during long field excursions.

Firearms instructors and civilian rifle owners receive a reliable, wear-resistant product with precise threading options tailored to their barrel profile, ensuring consistent point of impact and stability when correctly mounted.
