JP Enterprises has designed an operating system that reduces, or completely rids many of the problems you will find with other operating systems. Most notably is that you no longer need to use a carrier that relies on a central slug weight for proper operation, so it plays well with JP's Silent Captured Spring. This design also reduces the problem of bolt bounce and when used in conjunction with the 9mm captured spring, the system has a reduced stroke length making for a faster firing impulse. The Silent spring is also quieter in operation than a standard spring, especially useful when shooting suppressed.
