The Maxim Defense JP Silent Captured Spring System is engineered to work seamlessly with Maxim Defense CQB Stock System, delivering a refined recoil impulse and smoother cycling for AR-platform firearms. Crafted from tungsten and stainless steel with a silver finish, this standard-size capture spring is built as a precision replacement that integrates directly into compatible bolt carrier group assemblies where an open channel accommodates the guide rod passage during firing. By combiningMaxim Defenses expertise with a purpose-built design, the JP system helps manage felt recoil and maintain consistent aiming drift, making it an ideal choice for shooters seeking enhanced control in tactical scenarios, precision drills, and demanding field use. This dedicated rifle recoil part is designed to operate quietly and reliably within the system, supporting repeatable performance without adding bulk or complexity to the platform. While not a generic upgrade, its tailored fit for the JP model and CQB Stock configuration ensures compatibility and streamlined installation, enabling shooters to optimize reliability, reduce vibration, and preserve accuracy across extended shooting sessions.
