IMPORTANT WARNINGS AND INSTALLATION NOTES:

Advanced Installation: This product requires intermediate/advanced technical knowledge. Installation by an experienced technician is strongly recommended. Improper installation may compromise operation or damage the component.
Mandatory Threadlocker: It is necessary to use a drop of strong threadlocker on the fixing screw during installation and wait for it to dry completely (preferably overnight) to prevent thread damage.
Potential Feeding Issues: In some configurations (especially with low gas pressure), the perfect seal may cause feeding issues. If this occurs, simply remove a small spacer/shim present on the piston head.
FPS Increase: An increase in FPS is possible, but requires synergy with other custom parts and advanced tuning skills.
