And no, the new barrel dont have an internal o ring, my friend/gunsmith prefer to add a litle cone to the needle. Thus, a possible deformation of the pellet is avoided when passing through an O-ring and a perfect seal is achieved with less wear. See the photo:
Thats why I asked the question , I did it and the same happened to mine , so , cheap effective non tech resolve , dare I say it might have been designed like that ?
