Its regard to the female air transfer tube, I know there is a little oring on the tip of it but when I had the parts back from anno I realised that the oring was fitted inside the Asa and too big to fit on the tube. Not sure if its safe to air it up but it seems the oring will still stop air from leaking out between the ASA and the transfer tube. Just want to be sure if this is fine, I don't have any spares at the minute and need the gun for the weekend. Also I can't screw the female tube all the way into the frame otherwise it will pushes the ASA rail further out leaving a gap between the frame and the asa, so I just screwed it in about 90% to fit the asa on properly is this like normal or...?
