Griffin Armament's new M4SD-L (LIGHTWEIGHT) sound suppressor is the first laser-welded tubeless suppressor to be introduced in Griffin's Gate-LOKTM product line. This design makes the M4SD-L lighter than other Gate-LOKTM model. The combination of ECO-FLOWTM baffles, Gate-LOKTM mounting system and pressure-reducing flash hider results in a lightweight, durable and efficient next generation suppressor.
The M4SD-L is equipped with the Griffin Gate-LOKTM mounting system, which allows for quick installation and removal with the possibility of mounting the device on most USGI-spec A2 NATO compensators, as well as on all Gate-LOKTM muzzle devices made by Griffin. The GATE-LOKTM system is faster and easier to use than the A2 standard and provides a strong, aligning attachment with minimal mid-hit point offset and exceptional shit consistency.
Every single baffle in the M4SD-L has been tuned for superior sound reduction and features Griffin's patented ECO-FLOWTM technology to reduce pressure and increases the flow of gasses. This makes the suppressor system more reliable and reduces gas and sound pressure at the shooter's ear and face, without sacrificing sound and flash suppression.
The patent-pending pressure-reducing flash hider features high-performance internal and external flash-reducing components as well as optimally tuned vents that not only further reduce flash but also improve sound perfromence when combined with ECO-FLOWTM baffles.
Asked about the suppressor, Austin Green, head of product development at Griffin Armament said:
We manufactured the M4SD-L for demonstration to the military and provided many units to the military for as yet ongoing T&E. This GATE-LOK model was intended for experienced end users seeking greater optimization for real world conditions. This suppressor is now available for the consumer and export markets. The M4SD-L combines a wide range of innovative Griffin engineering developments to bring an incredibly well- rounded suppressor to market. The M4SD-L also shows our current customers our continued commitment to the Gate-LOK suppressor lineup, and to it’s development and optimization.
