KVP stainless steel suppressor booster pistons are a great option for use on several suppressor platforms. To maintain tight tolerances, KVP pistons are machined in a single Swiss CNC setup. The single setup minimizes the potential for tolerance stack up, in comparison to multi machine production strategies. The pistons are Black Nitride treated to improve durability and wear resistance.
