Strategic Sciences MFMD 5.56 0.0 OTB Suppressor -- MD Only

5.56 NATO ? 1/2x28 Direct Thread ? 0.0" Flush Mount ? Inconel Flow-Through ? NFA The MFMD-MD is an NFA-regulated muzzle device engineered to deliver measurable signature and recoil reduction on 5.56 platforms. Designed for rifles with 1/2x28 threads, it mounts flush with a 0.0" over-the-barrel requirement--installation is possible only when the barrel shoulder sits even with or ahead of any obstruction, ensuring a true direct-thread interface. Installs using included shims and torque tool--no adapters required. Developed under contract with the U.S. military's Irregular Warfare Technology Support Directorate and engineered by Russ Oliver, founder of OSS Suppressors. 3D-printed monolithic Inconel construction. Flow-through internal geometry manages gas forward--no traditional baffles, no backpressure increase. Flash reduction approximately 40% vs. baseline flash hider. Sound reduction approximately 17 dB at right ear vs. baseline. Rearward recoil reduction approximately 53% vs. baseline. Bolt velocity change ?2% from baseline. Black finish. NFA rules and regulations apply. All NFA items require tax stamp and transfer through licensed FFL dealer.

Flow-Through Inconel Construction

3D-printed monolithic Inconel construction with flow-through internal geometry manages gas forward--eliminates traditional baffles and backpressure increase. The design vents combustion gases forward rather than rearward, keeping bolt velocity change to ?2% from baseline.

0.0" Flush OTB Mount

Requires 0.0" over-the-barrel clearance--flush mount from barrel shoulder to first obstruction. Installation is possible only when the barrel shoulder sits even with or ahead of any obstruction. Measure carefully before ordering; if you don't have the clearance, it doesn't fit.

Flash Reduction

Approximately 40% flash reduction vs. baseline flash hider. The flow-through geometry redirects and cools combustion gases forward--reduces visible flash signature measurably in laboratory testing.

Sound Reduction

Approximately 17 dB sound reduction at right ear vs. baseline--achieved without SD or SDX extension components. The MD-only configuration delivers hearing-safe performance in compact dimensions.

Recoil Reduction

Approximately 53% rearward recoil reduction vs. baseline. The forward gas venting redirects propellant energy--reduces felt recoil and muzzle rise for faster follow-up shots.

No Bolt Velocity Change

Bolt velocity change of ?2% vs. baseline across all firing schedules. The flow-through design does not alter weapon cycling characteristics--no adjustable gas block required on host weapon.

Direct Thread Installation

1/2x28 direct thread installation using included shims and torque tool. No adapters required--precise alignment achieved with included hardware.

Military Development Background

Developed under contract with the U.S. military's Irregular Warfare Technology Support Directorate. Engineered by Russ Oliver, founder of OSS Suppressors--the flow-through gas management concept originated with military suppressor development.

Modular System Compatibility

MFMD-MD is the standalone muzzle device configuration. Also available bundled with SD (short suppressor extension) or SDX (long suppressor extension) for increased sound suppression.

NFA Item

NFA-regulated item. Requires completion of NFA tax stamp process and transfer through licensed Class III FFL dealer.
