JPFC-HS (JP Hammer Stop / Hammer Stop Block) is a mounting/service part from JP Enterprises, designed for AR-15 trigger mechanisms. It serves as a mechanical hammer stop that limits hammer travel during trigger tuning and facilitates safe installation and adjustment of trigger components.

In practice, it is primarily used during the installation and adjustment of JP trigger systems – it helps prevent uncontrolled hammer strike against the receiver during testing and allows safer work when fine-tuning the trigger (especially with adjustable JP systems).
