The JP Silent Captured Spring System is manufactured exclusively for Maxim Defense Industries to work with the Maxim Defense CQB Stock System. It is supplied in a configuration for 9mm AR-platform assemblies and uses a tungsten/stainless steel construction. The design requires an open channel in the bolt carrier group assembly so the guide rod can pass during firing.
