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.
This product requires a T-N.T. dedicated bucking and is compatible with MARUI GBB inner barrels.
Due to the wide variety of original factory versions, if you are unsure whether this kit is compatible with your model, please provide a photo of your original hop-up assembly and contact us for confirmation.
