338-GPS GPMG/MMG
Built for Assault Teams. Trusted by Machine Gunners.
The RD 338-GPS Suppressor is engineered for any 8.6mm or 338Lapua/Norma general-purpose machine guns operating at the heart of next generation infantry combat. Whether on the move with assault elements or laying down sustained fire from a support-by-fire position, the 338-GPS delivers the reliability, control, and signature reduction that today’s warfighters demand.
Designed for hard use in extreme conditions, the suppressor features RD’s proprietary Breathable Technology® gas management system that reduces back pressure, cuts felt recoil, and toxic gas exposure to the shooter. The result: smoother cyclic rates, reduced weapon wear, and better shooter control during high-volume engagements.
The monolithic, salt-air–resistant construction is purpose-built to withstand prolonged exposure to heat, dirt, moisture, and abuse. Its direct-thread interface allows for rapid field attachment with zero modification to the host weapon, ensuring compatibility with existing and future .338 and 8.6mm platforms across the force.
Finished with a proprietary I/R non-reflective coating, the 338-GPS reduces both visual and near-infrared signature—critical for maintaining a low profile in contested terrain and under night vision observation.
From dismounted patrols to fire support overwatch, the RD 338-GPS Suppressor gives assault troops and machine gunners the edge: less signature, more control, no compromise.
