New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

The Redline Airsoft Poppet Shim Kit will allow the user to tune the airflow through the Fusion Engine Poppet Valve. The larger the shim, the greater the flow reduction through the valve. Redline's testing shows that the best range, accuracy, air efficiency, and reliable function is achieved by running your regulator pressure in the 70 to 90 PSI range. It is recommended that the desired velocity and pressure be set with the proper nozzle and regulator adjustments before shims are installed.
