Strategic Sciences MFMD 5.56 NATO 1/2x28 Muzzle Device Kit with SD and SDX 0.7" OTB FDE

The Strategic Sciences MFMD Kit in 5.56 NATO with 0.7" OTB clearance gives shooters the full modular system in one package, including the base muzzle device along with both the standard Suppressor Device (SD) and extended Suppressor Device (SDX) modules. This lets the end user configure the rifle for flash-and-recoil-only reduction with the MD alone, a compact hearing-safe setup with the SD, or maximum sound suppression with the SDX, all without buying separate units. Every component is 3D-printed Inconel with a flow-through internal design that avoids traditional baffles, keeping backpressure low and bolt velocity change minimal for reliable cycling across configurations. Installation is direct-thread onto 1/2x28 barrels using the included shims and torque tool, with no adapters required for any module swap. Finished in Flat Dark Earth, this kit is built for shooters who want to adapt their suppression setup to different missions or host platforms without committing to a single fixed configuration.
