The stainless-steel-constructed RYDER 9-MP5 is a duty-use suppressor for the H&K MP5 sub-machine gun. The suppressor attaches to a standard trilug barrel via SureFire's patented Fast-Attach mechanism, similar to the way our best-in-class SOCOM Series suppressors attach. The patented stainless steel baffles are extremely durable and highly effective at attenuating noise, and built-in spacers help prevent excessive carbon buildup.
