Balystik HPA US adapter for KJ / WE / VFC GBB

HPA Adaptor suitable for KJ / WE / VFC GBB or GBBR magazines with a 5mm thread. Also works with Stark Arms G17 and M&P9 magazines. Other models may be potentially compatible.

These HPA valves seal due to the resin lock addition on the thread, allowing for different levels of adjustment depending on brands and models. GBB magazines with base plate may require modification.
Never use PTFE tape.

These valves are only compatible with US style quick disconnect fittings, such as those from NINJA, REDLINE, VALKEN, and Wolverine.

These valves are not compatible with Marui magazines, EU fittings, and EU lines like Balystik.

Installation by a professional is recommended for HPA magazine modification as compressed air can pose a risk if not installed properly. Furthermore, exceeding the green gas pressure (110PSI) can cause material damage and severe injuries.
