Installation Notes

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.

Product Notes

※ It is recommended to apply a little screw glue before tightening the screws, and please don’t tighten them too much to avoid deformation of the inner wall.

※ When using this T-N.T. hop-up chamber, it must be paired with our proprietary bucking and is compatible with standard GBB inner barrels on the market. △ Note: Not compatible with the original inner barrel, as it is a proprietary specification.
