Kaw Valley Precision Gen 2 Suppressor Piston Features The Kaw Valley Precision Gen 2 Suppressor Piston is machined from stainless steel in a single Swiss CNC setup a manufacturing approach chosen specifically to maintain tight tolerances throughout the piston s critical dimensions. Producing the piston in one continuous machining operation minimizes the potential for tolerance stack up that can occur when a part passes through multiple separate machines each with its own small variance. This attention to manufacturing process translates into a more consistent fit and function when the piston is installed into a compatible suppressor host. Threaded at .578x28 the piston is built to a widely used thread pattern found across a range of suppressor and host combinations. A Black Nitride treatment is applied to the piston s surface a finishing process that hardens the steel and improves resistance to wear and corrosion compared to an untreated or simply black oxide finished part. This durability matters for a component that experiences repeated thermal and mechanical cycling every time the suppressor is fired. Designed as a Gen 2 revision this piston reflects an updated design intended to improve on earlier generation components from Kaw Valley Precision. For suppressor owners looking for a precisely machined durable booster piston compatible with several common suppressor platforms this Gen 2 piston offers a dependable upgrade option.
