JP ENTERPRISES 9mm Short Stroke Conversion Kit

The 9mm Silent Captured Spring is a drop-in component that softens recoil and reduces cycling noise and vibration in your 9mm carbine. The result is a refined rifle that's a pleasure to shoot. Paired with our 9mm bolt assembly, you have the most reliable 9mm operating system available.

This improved version of our 9mm SCS is the best option for reliability and durability with hotter ammunition. It's also the best pairing for use with non-JP bolt assemblies where a central mass needs to be removed. Removing this mass reduces overall reliability from the operating system, which can be offset by the addition weight in the SCS.

Package includes spring and instruction sheet.

Features:

• Simple, drop-in installation
• Quieter, smoother operation thanks to reduced vibration and friction
• Softened recoil, both felt and actual
• Completes the roller-bearing-like perfection of the JP operating system
• Sufficient deadblow effect to avoid bolt bounce
• Mass tunable via alternate masses
• Enhanced reliability and durability when shooting hotter loads
• Best SCS option for use with non-JP 9mm bolt assemblies
