JP 9mm AR EnhancedBolt™ Assembly
Short-Stroke Version

Machined to the same exacting tolerances as our bolt carriers, this third generation 9mm bolt assembly 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 Silent Captured Spring, you have the most reliable 9mm operating system that dramatically reduces bolt bounce while improving accuracy.

New to this revision is compatibility 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™.


  • Reduced stroke length for faster firing impulse when used with JPSCS2-9MM
  • Last-round lockback compatibility
  • Designed for optimal function with JPSCS2-9MM for a heavier operating system that reduces bolt bounce while improving reliability and accuracy
  • Rock-hard nitride finish provides remarkable natural lubricity and a fine cosmetic finish
  • Includes firing pin and retainer pin



Use of this bolt requires a 9mm Silent Captured Spring or 9mm buffer and spring. It will not function with standard AR-15 buffer components.

This bolt assembly is compatible with both Colt SMG-style magazines and Glock pistol magazines.

This bolt assembly is also compatible with our JP side-charging uppers.
