**Important Notice**
Your pistol may experience BB feeding issues due to light gas supply. Simply remove one spacer to resolve the issue. Alternatively, consult your gunsmith to fine-tune the setup to solve this problem.
An FPS increase can be achieved; however, additional parts may be required and advanced skills are necessary. Incorrect installation/adjustment may shorten the product’s lifespan.
* P.S.: Please note: installation/assembly of airsoft gun parts requires intermediate knowledge; recommended for experienced gunsmiths or airsoft technicians. Consult your airsoft gunsmith for proper installation/adjustment. Installation may vary as each airsoft gun’s condition can differ. Regular maintenance is required for all airsoft guns to keep them in good working condition and reduce wear on parts. Actual performance depends on your overall airsoft gun setup. Consult your airsoft gunsmith for advice. Strong threadlocker is required for installation. Apply a drop of threadlocker when installing the screw and allow it to dry overnight. The screw threads may be damaged if threadlocker is not used.
