The SilencerCo Multi-Caliber Piston in 13.5×1 LH threads (brand part number AC626) is machined from 17-4 stainless steel and heat treated for durability, giving you an easily interchangeable piston that keeps a booster-equipped suppressor cycling correctly across compatible host guns. Because the piston can be swapped for a sub-caliber version, the same suppressor can run smaller-caliber rounds without changing the can itself, effectively turning it into a multi-caliber suppressor. This 13.5×1 LH-threaded piston is compatible with the Octane Series, Osprey Series, Omega K Series, and Hybrid 46.
