Well then, maybe you can help me too. In 2015 I bought a HM 1000X in 25 cal and brought it here to NZ. Serial # 831 I have enjoyed shooting it, but it now has sat in storage due to a slight air leak. I believe it's in one of three places, the bottle, the intake fitting or in the gauge and intake manifold which I believe has two o-rings. My first step was to contact Airforce, on the only site I could find, asking them for the actual correct catalog designated numbers of these O-rings. We have a very good supplier of o-rings about ten minutes from here. I had no reply. Can you please help me to get this problem remedied, it's been out of action for near on 3 years now. Thank you for your help. Brian
