FX FX Wildcat BT Leak

Had a small leak in a new Wildcat BT I purchased and finally got time to look more into it. The bottle had completely emptied itself due to the leak so I went to fill it back up and as soon as pressure got back on the bottle, I could hear air coming out of the hole above where the bottle screws in. Any ideas on what could be the cause? Rear reg pressure is holding steady. This is my first air gun so any and all help welcome. Thanks in advance.

It’s simply an oring thing. Easy fix is completely subjective. On the surface yes just an oring change. I personally find them a royal PIA. There are videos on YouTube and like 5 or 6 orings to change. There is an oring in the bottom of the reg itself that is super hard to get back in to the right spot. There is one that is hidden pretty well down inside the gun body itself. In the threaded hole the reg unscrews out of. Super tricky as well. If you do it yourself absolutely get some non marring picks. Nylon or brass ones as to not scratch the oring sealing surface or you will have a permanent leak. The gun is also under warranty and can be sent to utah Airguns or cape fear Airguns if you are in the east coast. Unfortunately the same thing happened to my BT after a couple months. After struggling with the reg I sent it to cape fear.

So can I get with Utah Airguns even if I didn't purchase from them? Do they handle FX warranty issues in the states? I haven't adjusted the reg at all since I got it. It was tuned perfect for my pellet needs when I received it.
Yes Utah will handle the warranty even if not purchased there. What I did with mine was take the barrel, stock, bottle , scope and scope rail off so I could ship just the main part of the gun in a much smaller box. I shipped mine to cape fear and he was fine with it that way. I would just ask Utah if that is ok. They should have bottles to attach after resealing it to test so I wouldn’t think it would be a big deal. Also I’ve had two fail (not the same gun) and it wasn’t because anything I did. I have mine set to a pressure that will work for 25 heavies and.30 cal pellets and I’m not touching it. Don’t know if that will make a difference but so far so good after the fix.
 
Never had a regulator ( any of two on my maverick fail )
BUT ! Having a brain freeze and thinking i was handling my Two, i did unscrew the bleed screw,,,,, though it was my Maverick and the first regulator i unscrewed, worked just fine got air out of it, but it also cost me two new 2 X 1 mm O-rings.

Generally i have never really touched the front regulator on the maverick other than making sure it was set to 170 BAR.
 
I just repaired my Maverick that was leaking in the same place. It was the front regulator. I just got a regulator kit from Utah Airguns. Much easier than replacing all the orings in the regulator. Easy fix $54.
Funny you should mention that. UA just said they could ship me the regulator instead of me having to ship in the gun. If it’s an easy swap, I may opt for this route.

If you do that you should really replace the oring that is down in the gun body in my opinion. It may be the culprit of the leak actually.
 
Very easy swap except for one oring that goes in the gun. Need a good pick to get it out.
You may get away with not needing it, though.
Found a UA video on YouTube that showed the process. Doesn’t look difficult but will definitely need some brass picks. I‘ve done far more difficult things with centerfire rifles and looks like a great opportunity to learn how to work on the gun.

I’ve heard several people on here talk about using a long sewing needle. Giving it a slight bend at the very end and carefully stabbing into the oring itself and pulling it out. I suppose carefully is the key as to not scratch the surface of the groove it sits in. It’s hard to even see. Was for me, even with lighted magnifiers.
 
Just another helpful tip with this platform as I’ve had both the Maverick I had and the wildcat bt I have do this. The BT did this for the first time just this weekend. Prior to this happening both were spot on shot to shot velocity. Suddenly they will start throwing an erratic 20-30 fps low shot here and there. For me this has always been a probe alignment issue. If you follow the silver cocking rod toward the front of the gun you will see a small black block with 2 Allen screws. This block holds the cocking rod in place which holds the probe in proper alignment with the transfer port. If that slips the slightest the shot to shot consistency will suffer. If that happens I loosen those two screws and stick an Allen wrench down the access hole to the probe screw (hole is under cheek piece). Use that Allen to push the probe forward in that hole. The probe screw needs to be front of center when viewed through the access hole. I just push it as far forward as possible while still being able to unscrew it if need be, while holding it in that position tighten the two screws in the black block back up. That has always fixed the issue and brought the gun right back to spot on consistency. Easy fix but a definite weakness of the design.
