Desert Fox

Manufacturer: ICD Indian Creek Design
Year: 1998

The Desert Fox looks very similar to the blow-back ICD markers, but has a very different internal design. It functions much like an improved Automag; an open-bolt blow-forward design. Like the 'Cats, 'open-bolt' means the bolt is normally open so that a paintball can drop into the chamber at any time (though double feeding is normally prevented by a stop that holds the chambered round in place below the powerfeed). 'Blow-forward' means that the bolt moves forward under air power when the trigger is pulled, and the mainspring pushes the bolt back after the air is released to re-cock the gun for the next shot. Velocity is controlled via an integrated regulator. Increasing the regulated air pressure in the air chamber increases the energy transfered to the paintball. The advantages of the blow-forward design include higher Rate of Fife (ROF), less reciprocating mass to reduce recoil and marker jump while firing, and very consistent shot-to-shot velocity.

The original, or 'Classic' Desert Fox had a more complicated valve assembly which included an On/off valve to shut off the flow from the regulator while the bolt was released. In the earliest models this On/off used a ball-bearing seal which was troublesome, it was later replaced with a poppet-style seal, and all older valves are replaced when sent into ICD for repairs with the newer and more reliable design. The Classic 'Fox also had a rear ASA mount and an optional front-mount vertical ASA connection (which was useful for preventing liquid from entering the regulator and a common upgrade).
The Desert Fox was redesigned in 1998 to remove the On/off and reduce the chamber pressure of the marker. Low pressure operation is a hot feature in paintball, as many feel the larger volume, lower energy air pulse gives better accuracy and [slightly] longer range. For a detailed description of the operation of the 98 Desert Fox see Fox Tweaks: Regulator Theory and Tuning. The newer version also comes equipped with 45 grips, a double trigger, and removed the rear ASA for a vertical mount with swappable connections (1/8 inch NPT connections can be moved to either side of the marker, or a hose can be directly attached at the rear of the trigger frame).
