Frequently Asked Questions

What is the Strategic Sciences MFMD?

The Strategic Sciences MFMD (Multi-Function Muzzle Device) is a 3D-printed, over-barrel firearm accessory that integrates a suppressor, flash hider, and muzzle brake into a single unit. It's designed to significantly reduce sound, flash, and recoil.

What are the performance benefits of the MFMD?

The MFMD offers substantial performance gains. For 5.56mm out of a 14.5-inch barrel, it can drop sound to around 139 dB, reduce flash by 98%, and cut recoil by about 60%. The SDX variant pushes flash reduction to 99.99% with near-zero signature.

How does the MFMD's design work?

The MFMD is an over-barrel design, meaning it slides over the host firearm's barrel. This allows it to be relatively compact, similar in size to a K-can, while still providing significant suppression and other benefits without adding excessive length.

Are there different versions of the MFMD available?

Yes, Strategic Sciences offers variants of the MFMD, including the SD and SDX. These offer slightly different lengths and performance characteristics, with the SDX providing the highest level of flash reduction and sound suppression.
