Action Army HPA Adaptor for Marui EU Type

The Action Army HPA Adaptor for Marui EU Type can only be used on HPA hoses that have an EU type connection.

This HPA Adaptor from Action Army is particularly suitable for Marui brand gas magazines and replaces the GBB inhaust Valves. It may be possible if you want to continue using the end plates that you need to modify them. (Hole must then be drilled out slightly wider).
