Post subject:  Umarex XBG leaking CO2 (badly)

A friend gave me a TAC converter/XBG and it leaks co2 in a bad way...loudly hissing until the pressure drops and then seems to stop (can't hear it anyway) and then it barely punches through pop cans....

I tried using Pellgun oil, but it didn't help....and I tried a silicone lube spray...that failed....is there anything else I can try? Is there a seal that can be replaced to fix the problem or should I just buy a new pistol?

I am planning to give it to my 12 yr old daughter...whom is losing interest with her ol' Daisy Red Ryder...which will end up being mine, cause I love it :)

I know that R&R airgun might have umarex parts however I don't think it's worth the trouble of repairing so I recommend that you buy another XBG

It seems that the XBG is a really inexpensive airgun.

Worst case scenario you get buy another one but on the other hand you can try to repair it and learn something in the process.

It depends where the leak is coming from.

Is it from the handle? If yes it is probably the piercing pin seal.

If it is coming from the barrel, it is probably the valve seat seal.

Coming from the piercing seal you can try to make a plastic washer that will fit in the hole and use the material from a coffee can cover or best from a Nestley Quik container cover.

The material is fairly flexible and smooth. I used it to make a piercing seal for a Shakespeare Acro I and I fixed the face seal of the fire pin plunger seat for a Crosman Mark I and a Crosman 622.

Tried that.

You don't have too much to lose.
