Allows the air holding the bolt back in the front chamber of your Ion escape more quickly. Instead of forcing the exhaust air back through the restrictive tubing to the valve it is instead dumped out a port with much higher flow capabilities than the tubing and small barb on the solenoid.

This simple Mod will get you:

• Higher Bolt Speeds
• More Air Efficiency
• Lower Dwell Settings
• Shorter Cycle Time
• Higher Rate of Fire
