The Kaw Valley Precision Gen 2 Suppressor Piston, .578×28 (Kaw Valley Precision part no. KVPPISTON1803) is a threaded mounting insert, not a suppressor itself, that fits inside a compatible quick-detach suppressor to let it mount onto a barrel or muzzle device threaded .578×28. Pistons like this are a common way to adapt a suppressor’s quick-detach mounting system to a specific thread pitch without altering the suppressor’s NFA-registered configuration. The Gen 2 design refines fit and durability over earlier piston generations for a more secure, repeatable lockup. This piston is an accessory component and is not itself a regulated NFA item; the suppressor it mounts to remains the Title II firearm requiring its own registration and transfer.
