JP 9mm AR EnhancedBolt™ Assembly
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.
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™.
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 not compatible with Colt SMG-style lowers and magazines.
This bolt assembly is also compatible with our JP side-charging uppers.
