If your HPA or CO2 airsoft gun requires an upgrade or replacement, consider this Ninja MicroBore Remote with Slide Check and Quick Disconnect. It works with all HPA systems and is fully assembled straight from the factory. You only have to install and connect everything before firing.
The remote is designed to endure 4,500 PSI of working pressure and is made of rubber, aluminum, and brass for this purpose. The hoses are 33% thinner and lighter than stock examples as well.
An ASA adapter and slide check de-gas the marker and stop the airflow in the hose. With a microbore line, the system is even lighter and easier to fit inside your weapon.
