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.
Please note that GHK-AR V2 and V3 have slight design differences. Kindly confirm your model before placing an order.
This T-N.T. hop-up chamber requires the use of our proprietary bucking, but is compatible with standard inner barrels on the market.
The outer diameter of the H+ / HS+ inner barrel is 9.95 mm. Before purchasing, please make sure the inner diameter of your outer barrel is large enough for proper installation.
