Key Information
AirTac use a US Foster Fitting as standard. This is the most common airsoft HPA fitting.
Some of AirTac's HPA adapters have a smaller internal volume than gas magazines. Because of this, you will need to use a PSI of 90–150.
If you need higher FPS, you can:
Fit a tighter barrel
Use a longer barrel
Use heavier BBs
Fit an improved hop bucking
If your replica has an NPAS fitted, we advise opening it fully.
Do not exceed 150 PSI. Many airsoft guns will not see an increase in FPS past this, as the hammer may struggle to depress the valve correctly.
Insert the HPA adapter with your bolt / slide locked back to minimise pressure against the nozzle loading arm.
Additional Information
DO NOT EXCEED 150PSI WITH ANY AIRSOFT HPA ADAPTER.
ALWAYS USE AIR REGULATED BY A SECONDARY REGULATOR (EG AT200, WOLVERINE STORM, POLARSTAR MRS).
CHECK YOUR PSI BEFORE CONNECTING AIR TO A HPA ADAPTER.
NEVER CONNECT AIRTAC'S EQUIPMENT TO PAINTBALL AIR TANKS OR CO2 TANKS.
NEVER CONNECT AIRTAC'S EQUIPMENT TO A TIPPMAN STYLE HPA LINE
