Got bored today. Shot some in the back yard. thought of all the hard work that went into this thread, and figured i would just toss some random BUMP post so that anyone who got AirForce rifles for christmas or tax returns can see the progress. Happy shooting folks!
On my Talon SS .177 I just tried using an o-ring.O-ring size #4711/32"OD x 7/32"ID X 1/16" thickor.343" x .218" x .065"My top hat clearance was .078".It was ok, in that my groupings were good for about 30 or 40 shots, then it went to *(&^. The o-ring gets sucked into the brass fitting between the valve stem and brass fitting that screws into the bottle. That's a no go.
