Get a strap wrench to remove the valve but make sure all the air is out of the bottle. If a little is left the valve won't turn. You could maybe try using a piece of leather and a pair of channel lock pliers. Good luck.
Years ago I had all the best powder burner varmint calibers and guns. Forty years later I still don't think you can beat an acurized 700 Remington 22-250 Ackley shooting 80 grain Serria bullets. Now I shoot FX Royals smooth twist guns shooting pellets and for what I shoot they can't be improved...
I called AOA on Thursday and asked about an o ring kit for an airgun they no longer carry. I was transfered to Shane who said he could put a kit together and send it right out. I received it today, Monday and everything that I needed was there. Thanks for being quick and efficient.
Can you do what you want with what you have? I only shoot birds at dairies so the FX Royals I have fill the bill. If I wanted to shoot slugs then I would need an airgun that will shoot slugs. Sounds simple but probably not.
Cases hard or soft can attract moisture. I think a safe with a heated rod or some kind of dehumidifier is best. Temperature extremes high and low are bad too.If you live in a dry climate, that would help.
I have the newer model Aztec Emerald 5.5-25X50 with target knobs, illuminated reticle, and zero stop. I haven't seen any reviews or comments yet. Anyone else have this newer model with any positive or negative comments? Thanks.
