• Reduced stroke length when used with JP 9mm bolt
• Greater mass than most 9mm buffer systems
• Allows for minimal bolt bounce
• Quieter, smoother operation

The JP 9mm Silent Captured spring will increase the reliability of your firearm, while speeding up accurate second shots. The extra mass in the buffer helps the blowback style action operate smoothly and consistently. It will also help to reduce the stroke length of your operating system, especially when used with the JP 9mm bolt. Another great benefit of this product is that it will mitigate the amount of bolt bounce, which in turn leads to a faster firing impulse.
