is there a vent hole in the air tube?
tell the whole story about your gun, was it regulated from the factory? or a conversion?
what gun is it?
better descriptions will get you a more defined answers

It has a vent. But this was a more can it be done question. I would like to do it to a gun of mine. I don’t shoot it much but would like it un regulated for a more robust gun.

Bander,
Regulated is the only way to go for me. Unregulated provides too much air up front, and too little at the end, to meet the preferred pressures my pellets find most accurate. While not allowing for more shots, a regulated airgun provides more consistent shots since same amount of air is released from start until finish when reservoir pressure falls below regulator setting.

You *should* be able to modify any reg body to technically remain in place and take full pressure. I can simply unscrew my reg adjuster/seat enough to where it never contacts the piston and the gun acts as if its unregulated, operating the reg outside of its usable range. Could also remove the adjuster or piston and spring/bellevilles itself entirely if its applicable.

Also, you'd have to change the hammer spring/weight more than likely to operate the valve at much higher pressure than designed when regulated. Probably better to gut the reg from the washers/springs and piston so they aren't under extreme wear from the excess pressure.

I have an uragan 1 with its second regulator and second issue with the reg. It’s a pain to get to and I would love to just shoot it with out crazy creep or the new thing it started doing every shot is faster than the previous clear past the regulator set point then once pressure drops to about 60 bar it starts back down. I mean extreme spread of 500 fps 
. If it were possible to just shoot in regulated I can deal with the curve and be happy.

There is Huma of course....I did have an uragan with faulty reg also and was very frustrating. Mine came like that new though so I returned it.

While it is possible to make a gun unregulated, you will have to keep fill pressures lower than you would an actual non regulated gun. The hammer strikes need to be harder due to higher pressures, and so unregulated guns tend to have heavier hammers and springs to overcome these pressures. There is other things involved, but all in all, doable With the right extras. Not sure you would have a “more robust” gun from removing the regulator though. There’s much more involved to making a gun more reliable. There are plenty of robust regulated guns out there like the tsipans, evols, etc.

A non regulated rifle normally has a stronger spring in order that the hammer opens correctly the valve. It should be an equilibrium in the force of the preassure of the tank and the power of the hammer.
A rifle designed to open the valve with regulated preassure will not open correctly the valve with the full preassure of the bottle.

So…. After reading everyone’s posts over and comparing it to what I was experiencing. I spent a lot of internet searching. I believe I was shooting unregulated. The higher the fill pressure the lower the speed until 110 bar at that point it peaked even though my reg said it was 80bar. So with serious cringe I was able to get to the regulator. My gun has the pin wrench style before the reg. Pulled the reg and noticed this one was further un screwed than the other ones I’ve installed. I believe it was out side it’s range on the high end by 2 full turns. Went a head and checked the Orings and washers. No damage. I reinstalled and viola it works but has a slow recovery about 15 secs but it works. Average deviation of 3 fps. Still don’t know the exact pressure but I’m still on the reg at 100 bar.

The first part is correct but the second part is wrong. There is a vent hole in the reg body that if you remove the spool and washers it would just leak out that hole. Now if you brazed that hole shut then you can do what you stated. The simplus thing would be to adj the reg so high it would be as though it wasn't there.

Been already said pretty much ...
If air tube has a drilled vent hole, it needs to get plugged or blocker made internally to keep air from exiting from it.
Regulator opened up to a higher setting ( basically bypass mode) will allow high pressure to be what ever tank is at .. BUT, the plenum is still present and power still won't be equivalent to the valve breathing off the entire HP tank volume. Air passes threw a Regs seat pretty slowly & even tho Reg is wide open & in bypass the air on HP side of reg is still not able to supply aditional air to the plenum during the duration of a valve cycle / shot.

Custom spacer to block the airtube vent. Basically the housing for a regulator but without the regulator in it.

Similar to an M-rods gauge manifold but far smaller / compact. Just a collar with an o-ring either side of vent hole and big flow unobstructing hole down the middle
