HPA valve without drilling, suitable for KJ / WE / VFC GBB or GBBR magazine with 5mm thread. Also Works on Stark Arms G17 magazines. Other models are potentially compatible.
These HPA valves boots seal thanks to the addition of blocking resin on the thread, allowing different positions levels depending on the brands and models. GBB magazine with talon may require modification.
These valves are only compatible with the pressure couplers and Balystik lines.
These valves are not compatible with Marui magazines and US couplers and line like NINJA and REDLINE.
Installation by a professional is recommended for modifying your HPA magazine because compressed air can pose a risk if the installation is not properly carried out. Furthermore, the fact of exceeding the pressure of green gas (110PSI) can cause property damage and serious injuy.
