The FN Rush(TM) 9Ti is a highly versatile and reliable 9mm suppressor, delivering an unmatched shooting experience. When paired with the FN 509 TacticalA(R), reliable feeding and extraction with most common ammunition types is the new standard, maintaining the exceptional accuracy, cycling reliability and high durability standards FN owners expect. With the advanced booster assembly, mounting the FN Rush 9Ti to any pistol barrel threaded A 1/2" x 28 is fast and repeatable. A tight piston gas seal contains carbon fouling in the baffle core, making for a smooth shooting experience without the heavy blowback and stoppages common with most suppressors. Mfg: Fn America
