AA S200 Seal issue?

[Oxy 0]

Hey everyone, I wonder if any of you can help me?

 

Today I was shooting my AA S200, and after about 30 rounds being cycled through with no issues, I came across a jam (This has happened before, the AA 10 shot magazine doesn't seem to be too...reliable.) And anyway, after removing the magazine, removing the stuck pellet I reloaded the magazine and placed it back in, then once I went to shoot again the gun simply returned a "hiss" sound and no pellet left the barrel, so I cycled another pellet and the same thing happened, took it home and now it's on my bed in a "stripped" state.

 

Here are some things I've noticed:

 

1. The "Hiss" only comes when I lock the bolt.

2. If I don't lock the bolt, it comes back and then forward again and produces the normal firing sound, however nothing leaves the barrel.

 

Anyone got an idea, or at least a suggestion as to what this could be?

 

Thanks, and any help is very much appreciated.

Have you checked the barrel for a lodged pellet or two, also did you check the probe "o" ring was intact they have a habit of blowing when you encounter a few pellet jams the same happened to me a few months back, easily replaced for about 60p: Dave
