I got my new pcp gun today it’s an sig sauer virtus. I spent the extra money and got an air compressor. My question is,,say I’m down to about a quarter tank and I want to go ahead and refill it. Can I unscrew it from the gun with a quarter tank of air left in it or do I have to somehow bleed all the air out first and then unscrew it to fill it up or can I fill it up while it’s still attached to the gun.?? I know that there’s warnings saying that it’s a very high amount of pressure and I just don’t want it exploding on me or something. Sorry if this seems like stupid question like I said this is my first one.
Sig Sauer New to this just wanna be safe

Madd,
Welcome, glad to have you here. Unfamiliar with that airgun but photo shows a male foster fitting near top of bottle. A high pressure air (HPA) compressor should have a fill whip (hose) with a female foster fitting which should attach to that for filling. No need to remove, or empty, bottle for filling, a one-way valve in airgun will hold pressure. Be sure to release pressure in fill whip, via pressure release valve on compressor, before disconnecting foster fittings. WM

Pyramyd Air's website states the MCX version of this airgun, in .22, has a maximum fill pressure of 3,000 psi with a regulator setting of 1100 psi. Most recommend refill when pressure approaches regulator setting. Research your pressure settings if not printed on airgun. WM
Its hard to tell, but in the picture It looks like on the neck of the bottle there is a foster fitting opposite the pressure gauge? The fitting is where you plug the compressor fill hose onto. Take some closer photos of the gun where i said to look.
Next thing is you need a pcp compressor to refill the bottle.

Either way is fine. I would prefer to fill it while on the gun. As said, it's a max fill of 3000 psi so you want to be careful not to overfill it. If your new compressor has autostop set it to 3000 but I wouldn't depend on it not to fail to stop. I never leave them unattended.
The tank is designed so it can be removed while charged. It's regulated at 1100 psi so you wouldn't want to run it lower than that.
With this set up you can purchase more tanks and carry them to the bench or out in the field and hot swap them.
Being new to PCP and HPA compressors you'll want to take your time and learn. HPA ain't no joke. Read your specific manuals for both and maybe watch a few videos online.

HPA can kill you.... that said, fill your guns bottle from the foster QD fitting at the neck of the bottle to no more than MFGR max rec safe working pressure. before doing any maintenance on your gun involving HP areas, always degas your gun.

I don't know if your compressor directions mention this, but the bleed valve on the compressor should be opened when starting the compressor against pressure (a non-empty bottle) and once the compressor starts, close the bleed valve for the fill. If you have to stop the compressor during a fill, again open the compressor bleed valve to release pressure, restart the compressor, close the bleed valve and continue your fill. Never start the compressor against pressure.

Welcome to Airgun Nation. Congratulations on your new PCP rifle. Beware, the rabbit hole is deep. HPA is a tool and you have to respect it.
YouTube is your friend. Here is a good video on your rifle to get started. Rick puts a lot of work into his videos.
I would youtube your compressor as well and watch whatever you can find.
Have fun!
