The SureFire SF Ryder 9 Piston in the M13.5×1 left-hand thread pattern (SureFire part no. PISTON-9-M13.5X1LH) is the threaded component that mounts an SF Ryder 9 suppressor to the barrel of the host weapon. SureFire designed it so one Ryder 9 suppressor can be used on multiple weapons. The piston is machined from heat-treated stainless steel and given a black nitride finish. It is made for the SF Ryder 9-Ti, the SF Ryder 9M-Ti and the SF Ryder 9-Ti2. SureFire designs and manufactures it in the USA.
