Reply To: Can you use Nitrogen in an airgun?
Prices vary widely by location. I pay $50 a year lease and $70 for fill (I shoot every day and have yet to fill my 6K N2 tank I got in February). $100 refundable deposit on the bottle. Since Air is mostly Nitrogen there is little difference in shooting characteristics. I ONLY use N2 because it is ALWAYS moisture free. You also do not NEED a regulator! I use a fill adapter from Joe Brancato with no issues at all. I do HAVE a regulator so I can tether to the bottle for long shooting sessions without pressure drop.
