AAC Illusion 9 Piston | 1/2×28 Thread | Bead Blasted

This piston is designed for use with AAC Illusion 9 suppressors to allow the suppressor to be adapted to barrels with a 1/2×28 thread pitch. It provides a threaded interface that is swapped into the rear of the suppressor so the unit can be moved between host firearms with matching thread patterns. The part is finished in bead-blasted black and is listed with a 9mm caliber/gauge designation.

Typical applications include range and training use where a suppressor needs to be transferred between multiple host barrels, and competition or match environments where quick thread conversion reduces downtime.
