Just picked up a Desert Fox and I want to gut the reg and stick a stab on it but I am not sure how to go about doing it.
Here is a valve schematic:

remove 11,12,13,14, and 25 and use an external reg.

IIRC

if you remove 14 and 25 then air is going to piss out the back of the gun.

You are totally correct. I throw myself on the mercy of the court.

As I often say, I am old and my memory is fragile.

Dan if you run into any problems Curt can hook you up, he gutted mine. Its pretty easy.

Yeah, it's pretty simple.

1. Remove rear adjuster, and take out the short stiff reg spring. Replace adjuster screw.

2. Gas up the gun. You'll hear a 'pop' as the reg piston pops out. Remove the adjuster again, dump out the loose bits. Wrap the adjustment screw w/ teflon tape to seal it, and screw it back in.

3. Remove the entire valve body- it's held in place by the large thumb screw at the back of the frame, just like on a Mag. Make sure not to lose the little o-ring that fits between the valve body and the frame.

4. Unscrew the front of the dump chamber. Not the brass tip, the whole thing. It's usually not too hard to get off.

5. Look at the front of the valve body, you'll see an allen screw w/ a washer retaining the brass plunger. Remove the screw.

6. Re-assemble the valve body, and re-install it onto the gun. Gas it up like you did before, you'll hear another 'pop' as the plunger gets ejected into the dump chamber.

7. Take it apart again, dump out the rest of the guts. Re-assemble.

A drop of oil will help keep the little o-ring under the valve body from falling out.

You'll need to contact ICD and order some piston o-rings (goes behind the brass tip of the dump chamber) and a couple spare mainsprings. The piston o-ring is good for about a case or so before it starts leaking down the barrel and the mainspring lasts about 2 cases.

Good luck and have fun. You'll love it.

I run my Desert fox deluxe on anti sypon co2(and so do 3 of my teammates) all are running the factory setup(x-chamber, 45 frame, pitched asa) and we have no problems with the reg. I can cycle my Fox so fast its been accused of being full auto, and I have no drop off. havent ever had to replace the main spring. and if you store the gun with the bolt removed from the power tube, you never need to change the power tube oring. just a couple of drops of oil in the power tube EVERY time you put a tank on it.
If run properly these guns are flawless, if a little tempature sensitive.

Interesting. I had nothing but trouble with mine until I Stab'ed it. Good idea about the bolt o-ring also. I keep mine lubed up but find that the mainspring gets un-sprung after about 4k shots and the bolt won't re-set.

once in a blue moon i need to change the main spring in Fox. but its so rare. I wonder what is causeing that? what preasure do you run? been shooting my fox since 99 and changed it twice maybe.
