Griffin Armament Revolution 9 MOD 4 9mm Suppressor, Modular Overview The Griffin Armament RevolutionA(R) 9 MOD 4 is a modular 9mm pistol suppressor designed for secure mounting, simplified maintenance, and flexible length configuration. The MOD 4 features a redesigned platform with tool-less length adjustment and disassembly, allowing the suppressor to be configured for either a compact or full-size setup. The Revolution 9 MOD 4 incorporates Griffin's patented CARBON-GARD(TM) baffle technology, which uses high-temperature silicone O-rings to seal the baffle interfaces and help prevent carbon and lead fouling from accumulating between the baffle stack and tube body. ECO-FLOW(TM) baffle technology further reduces backpressure. The suppressor includes a booster assembly with an EZ-LOK(TM) piston, providing a secure mounting solution for compatible host firearms. The permanently installed booster housing also accepts compatible pistons, fixed-barrel mounts, spacers, 3-lug mounts, and Plan A mounts.
