Are you using black orings or colored, sometimes the black ones are a little smaller, so try and grab a handfew out of your bag/box and find the best looking one,
if its comming out of the front of the bolt change the top hat 017 oring, and the can 017 oring, as far as leaking out of the back of the backcap, change your two tail orings, and just for the hell of it change your bolt sail oring
