Tuning Problem filling Brocock Bantam Sniper HR

[piinnh]

After not having used the Bantam Sniper HR for a long time because of health reasons I found the gun did not loose any air pressure. Thats the good part. I took it out and shot it until it was just about to go below the 140 regulator setting. I refilled it from my tank but it did not take a complete fill. I shot it again and took it down until it was off the regulator but it would not take any air at all after that. I took the pressure down to zero and it would still not take any air. Any idea what is going on here?

Thanks

when you say "would still not take any air". Do you mean you could not get air in to the bottle? or did it all leak out after you filled it?

Does your tank have enoigh pressure inside it? 



As the tank drops pressure, the airguns don't refill back to max pressure like a full tank. They will be equal to what's in the tank. Like of the tank only has 210 bar.. the airgun will fill to that pressure not 250 like max on the actual gun.

I have the same gun in 22. 

When my guppy is full at 4500 psi I can get a max fill on my gun. But once my guppy starts to get down in pressure closer to 3000psi the gun will only fill to the msx pressure currently in the tank.

Thank for replies,

I guess I did not explain well enough. My charging tank is fully charged at 4500 psi. I connect to fill port on gun and needle on charging bottle/tank jump to 200 bar like gun is full but it has no air in it.

The gun is not taking any air. I have not tried a hand pump, going for cervical surgery tomorrow and do not want to even try.

Are you using a an extended Foster connect fitting in your fill whip? Can you hear air escaping from anywhere when you turn the valve on? 

 

[piinnh]

Yes, I have the extension and there is no sound of air escaping from anywhere.

If your fill station gauge is "jumping" right to 200bar in a matters of seconds then the check valve on the foster on the gun tank is stuck.

This thread should provide you with some help

Thanks everybody, Will call AOA and get their idea of how to handle it. I am sure Big Tin Boat is right about the check valve being stuck. Ill update this thread with what AOA suggests.

You have a bad fill valve. Unfortunately it’s a problem common to these guns. My Sniper XR had the same issue after about 300 pellets. Easy fix though, you can find a replacement 1/8 bspp hex foster fill valve on Amazon. Unscrew the factory valve with some needle-nose pliers and put on the new one. That’s what I did and it still holds air 100% after six months.

How is it a “common issue with the Bantam?” I’ve read less than “six” complaints about it here on AGN. “Common issues” heck have you read some of the FX posts? Those are examples of “common issues”...

Thanks again everyone. After reading the posts here and following the link to another thread, I went to the gun cocked it left the probe open and the gun took air all the way full. Not sure what really happen....

I am going to buy a new fill assembly and ring set to have as backup in case this happens again.

Getting ready to head out for spinal surgery, so two weeks before I shoot again.

Happy shooting,

C, good luck with your surgery! I’ve had a couple cervical surgeries myself. Follow the aftercare instructions, and don’t rush rehabilitation. As my brother said, this neck needs to last the rest of my life. If I can answer any questions, don’t hesitate to contact me.

I would put a few drops of Silicone Oil in the probe hole and in the probe itself if it has a probe, if it's a fosters, do the same, put oil in the hose, then try to fill it, the oil will lube the valve and help unstick it,

Scott,

Thanks, after now 4 back surgeries I have learned to listen and take it slow. Besides last time I got frisky my wife threatened to break my legs and she's a nurse.....

Update and a good one. Emailed AOA and explained the problem with the fill valve on my Bantam Sniper HR. The AOA service department got back to me and said Brocock have designed a new fill inlet valve and will send it to me free. I also enquired about a Inlet Valve Removal Tool and they told me they would send that free as well.

Feeling good about this, hope it helps others.

@piinnh, if you would, please post up some pictures of the new inlet valve. I have over 5K pellets and counting through my Bantam and have not had the issue reoccur, would like to see what the change is.

Will do, I have included the instruction sheet they sent today.

Sounds like the folks at AOA have taken good care of you. It's always good to hear reports of quality customer service, especially during a time when phone calls and emails often go unanswered. I know the pandemic world has placed a huge strain on everyone, but responding to customers who have already spent their money should be a top priority.
