Griffin Armament Revolution Features The Griffin Armament Revolution 9 MOD 4 rebuilds Griffin s original modular length pistol suppressor around a package of end user improvements that make the can more secure easier to mount and simpler to maintain. The forward extension allows tool-less reconfiguration between the 6.56 inch short and 8.31 inch full-size lengths while O-ring biased extensions and front caps prevent the extension or cap from loosening unintentionally. The permanently installed booster housing accepts pistons fixed barrel mounts spacers Griffin s integrated 3-lug mount and Plan A mounts so tightening or loosening the suppressor never loosens the housing itself. Every Revolution 9 MOD 4 ships with an EZ-LOK piston that provides a dramatically more secure and rapid mounting system than direct thread alone. Griffin s patented CARBON-GARD baffle technology places high temp silicone O-rings at each baffle interface the blast chamber and the extension tubes fully sealing gases and carbon within the baffle stack. That seal keeps lead and carbon fouling from building up between the tube body and baffle core preventing the carbon-locked baffle stacks that make cleaning other pistol suppressors a chore even after moderate round counts. Built from 17-4 H900 heat treated stainless steel baffles and a 7075-T6 aluminum tube body and end cap the suppressor weighs just 10.2 ounces in the short configuration. Rated for full auto fire and finished in black the Griffin Armament Revolution 9 MOD 4 is available at GrabAGun for 9mm shooters who want a modular maintenance-friendly suppressor built to last.
