Tuning Air Venturi Avenger 25 -- won't hold a charge / leaking air

I've had my Avenger 25 for a few months now and have shot a few 100 pellets through it. My favorite rifle. Unfortunately today when I pulled it out of the gun bag and attempted to fill it with air, I discovered it won't keep pressure in the fill tank and you can hear air leaking out inside the rifle close to the trigger. I'm assuming one the internal seals is broken or needs a replacement O-ring. Any ideas on what might be the issue? Any suggestions or pointers on how to disassembly and repair it myself? Any repair videos? Thanks in advance. 


 
Request for a return shipping label if possible so you don't add to the cost of ownership.

Their poppet doesnt even have a replacement part number. Pretty clever of them from a business standpoint after the warranty expires you have to buy another gun if you arent mechanically inclined and source aftermarket parts IMHO...

If you want it to last then run the reg pressure very low and baby it.

Welcome to the Nova air gun adventure! HOW TO KEEP THE DURN THING FROM LEAKING!!!!!!!!!!! I have a aspen that leaks like a sieve and is basically a $400 paper weight. My liberty, the avenger's older brother leaked when I got it. It's more than likely the poppet as has been stated before. Some times if you're lucky something will get caught in between the poppet and the seat but most times the poppet sealing surface is just plain wore out and it's bottoming on the metal can that incases the poppet sealing material. Send it back for warranty repair.

You can still fill it by first saying a prayer and use the fill probe to plug under the pump lever and use a tank or hand pump to try to force a seal and may hold if you just pray to JESUS hard enough.
