The Advanced Armament Ti-Rant 9/Evo-9 Piston in 1/2×28 (Advanced Armament Corp part no. 64192) is a 9mm booster piston built to mount a threaded pistol barrel to an Advanced Armament Corp Ti-Rant 9 or Evo-9 suppressor for reliable cycling on a semi-auto host. The piston itself is an ordinary Title I mounting accessory, not the suppressor; it is the part that lets the barrel and slide cycle correctly with a suppressor’s added mass on the muzzle. It threads onto a 1/2×28 pistol barrel, the most common 9mm handgun thread pattern. Pairing the correct piston to your specific host pistol is what keeps a suppressed 9mm pistol running reliably.
