The Energetic Armament Sonus is purpose-engineered for 9mm pistols, PCCs, and subguns, using heat-treated 17-4 stainless steel (H900 condition) to achieve an optimized balance of wall thickness, internal volume, and durability at just 9.8 oz. The precision-welded construction allows thinner walls than traditional machined designs, increasing internal volume within the same outer envelope for better suppression efficiency. Ships with a 1/2x28 direct-thread adapter installed and features a 1.375x24 HUB-compatible end for quick-detach mounting systems — giving shooters the flexibility to run either. The removable end cap includes a wipe holder as standard, and the Sonus is rated full-auto for 9mm with no barrel length restrictions below 1,000°F.
