Strategic Sciences MFMD + SDX 5.56 Suppressor - 1/2x28 - 1.3" OTB - Black

The Strategic Sciences MFMD 5.56 Suppressor lets users streamline a rifle setup by combining sound suppression, flash reduction, and muzzle brake recoil control in one device. Built for 5.56 rifles with 1/2x28 threads and 1.3" of over-the-barrel clearance, this multi-function muzzle device delivers measurable performance without sacrificing the rest of the rifle's setup. The SDX (Suppressor Device Extended) is a quickly detachable extension that further improves performance and is made from the same 3D printed Inconel 718.

The MFMD cuts recoil by 64%, which improves control and shot-to-shot recovery, and its 98% flash reduction helps users keep visual awareness in low-light environments. At 138.5 dB as a standalone device, it reaches hearing-safe levels without additional attachments. The system is modular, so users can easily add or remove the included SDX extension.

This MFMD requires 1.3" of over-the-barrel clearance, measured from the barrel shoulder to the first obstruction, and it will not fit if that clearance isn't available. Installation is direct thread only, with no adapters required. The device is 3D printed from Inconel 718, which offers heat resistance, strength, and durability for sustained, high-pressure firing. It suits duty rifles, defensive setups, training, and suppressor-ready builds where recoil mitigation, flash control, and compact modular suppression matter.

Strategic Sciences designs the MFMD around precision manufacturing, aiming to give users a compact, modular system that handles recoil, flash, and sound.
