Due to dimensional variations and manufacturing tolerances among different brands, minor fitting adjustments or modifications may be required when installing T-N.T. upgrade kits. For optimal performance, installation by users with basic DIY experience or a professional airsoft technician is recommended.
Installation Notice: The original adjustment dial groove is relatively narrow. It is recommended to widen the groove following the original angle before installation (DIY experience recommended).
This product is compatible with MARUI-spec GBB buckings and barrels.
