JP Enhanced 9mm AR Bolt with 9mm SCS
   for Law Tactical Folder

The Law Tactical Folding Stock Adapter is far and away the most popular and capably designed device of its type. With the release of our Law-compatible AR-15 and AR-10 Silent Captured Springs, the only missing piece was compatibility with our ultra-reliable 9mm blowback operating system components. With this new operating system package, that piece is missing no longer.

Thanks to a great collaboration with Law Tactical, JP is proud to offer this conversion package to bring the Law folder and our premier 9mm Operating System together. This three-piece design underwent multiple concept iterations and a battery of harsh failure testing. The final result finally provides the superior cycling benefits of our 9mm internals with no dependability compromise for your Law folder-equipped PCC.

This operating system package includes:

  1. 9mm bolt assembly (Law-specific model)
  2. 5H2 Silent Captured Spring (3 steel mass/2 tungsten mass)
  3. Bolt carrier extension
  4. Buffer retainer pin & spring
  5. Spacer shims
  6. Installation instructions

This operating system package centers around a JP Enhanced 9mm Bolt Assembly redesigned to function with the included bolt carrier extension piece. This extension piece will not fit previous generation JP 9mm bolt assemblies and so both components of this package are required for function.

Weight: 26 oz. (with bolt carrier extension)

  1. Reliable, duty-ready compatibility with Law Tactical folding stock adapter
  2. Reduced stroke length for faster firing impulse
  3. Optimal function with JP Silent Captured Springs for a heavier operating system that reduces bolt bounce while improving reliability and accuracy
  4. Tighter firing pin channel to reduce pin wear
  5. High-energy tumble process producing a finer cosmetic finish

More About Our 9mm Operating System:

Machined to the same exacting tolerances as our bolt carriers, our newest generation 9mm bolt assembly entirely eliminates the need for a central mass (slug) to readily function with our 9mm JP Silent Captured Spring without compromising bolt weight and reliability. In fact, when combined with our JP Silent Captured Spring, you have the heaviest, most reliable 9mm operating system that dramatically reduces bolt bounce while improving accuracy.

The complete JP 9mm operating system is slightly heavier than the complete RRA bolt and buffer, some of the bolt mass having been transferred to the SCS in our system.

In addition to use with our full-stroke Silent Captured Spring, this revision is now compatible with our line of short-stroke Silent Captured Springs. This bolt assembly will provide reliable last-round lockback with any compatible receiver such as our GMR-15™.


  • The JP 9mm bolt assembly is not compatible with Colt SMG-style lowers and magazines.
  • The bolt assembly is also compatible with our JP side-charging uppers.
  • For function with the Law Tactical folding stock adapter, the bolt assembly, bolt carrier extension, Silent Captured Spring and buffer retainer pin included in this package must all be used in conjunction.
