This Kaw Valley Precision Gen 2 Suppressor Piston in 1/2×36 is a stainless steel booster piston in the BPISTIN pattern (brand part no. KVPPISTON1801). Kaw Valley Precision machines it in a single Swiss CNC setup so there is less tolerance stack-up than with multi-machine production, and black nitride treats it for durability and wear resistance. Match the thread size to your suppressor and host before ordering, since the Gen 2 piston is offered in six thread sizes. It is a replacement or upgrade piston for owners of supported suppressors.
