HI All, Got my mates 2009 air arms s410 leaking ,he told me he put to much air in it so been a good mate i said i would renew all the O rings for him, replaced the cylinder and filler probe ones , put some air in and its comeing out of where the bolt goes in that holds the shock on , I slid the barrol out but there was no O rings in there but i could see a brass bit infrount of were the barrol goes but i dont no how that brass bit comes out i can see it has O ring on it, any idea thanks bob.

The brass barrel collar will not leak continuously. It only affects point of firing and usually has no O rings but may have one if its a bad fit. It’s not the problem here though, either way.
(The brass collar is supposed to be loctited to the barrel).
If you have a leak near the stock bolt hole are you sure it isn't the gauge block leaking where it meets the body? That would leak continuously.
Soap it up with a bit of Fairy and water on a brush. There's 2 O rings at the joint I think.
