Energetic Armament is excited to announce a new finish option for the popular Sonus 9mm suppressor — Black Nitride. Since its launch in 2023 the Sonus has earned a reputation as one of the most versatile suppressors in the EA lineup, rated for 9mm NATO full-auto, 300 BLK, 38/357 Mag, 8.6 BLK subsonic and more. The original MetOx burnt bronze finish gave each Sonus a unique one-of-a-kind look that set it apart on any platform. Now shooters who prefer the clean tactical aesthetic of the EA centerfire lineup can get that same proven performance in Black Nitride.
What is Black Nitride?
Black Nitride is a thermochemical surface treatment that chemically bonds with the steel at the molecular level — increasing surface hardness and corrosion resistance without adding dimension or weight. Unlike coatings that sit on top of the metal surface, Black Nitride becomes part of the steel itself. It’s the same finish used on the PEAK 30, VOX-S, VOX-K2 and FEROX — purpose-built for hard use, consistent in appearance and proven in the field.

Two finishes. One suppressor.
Both the MetOx and Black Nitride Sonus are available now at $849. The MetOx finish with its unique burnt bronze appearance remains a favorite for shooters who want something distinctive. The Black Nitride brings the Sonus into the tactical centerfire family aesthetic — clean, consistent and ready for duty.
