Foxtrot Mike Products introduced the ISU-9 integrally suppressed 9mm pistol-caliber carbine upper receiver in October 2026. This new hardware allows users to attach a suppressor directly into the upper assembly for a more streamlined firearm configuration.
Why it matters
The ISU-9 provides a specialized solution for shooters looking to incorporate suppression without the need for traditional modular barrel attachments. By integrating the suppressor directly into the upper receiver, the design offers a dedicated setup for specific 9mm platforms.
The ISU-9 is priced at a $499 MSRP and is available through FM Products, Primary Arms, and Silencer Shop. It requires attachment to a user-provided serialized lower receiver to function as a complete firearm.
