Nitrogen and co2
Do you mean an air Rifle? NO, Not in the United States.
Compressed air and Nitrogen are the same thing. Some people call it "nitrogen" because air is 78% Nitrogen. Yes it can run on high pressure air, as well as CO2.
It all depends on the individual air rifle. I can average between 50 to 80 depending on the rifle I'm using.
nitrogen is 78% while CO2 is part of a percent
The threads are different on Nitrogen tanks. There are adapters to use a Co2 gauge on a nitrogen bottle .
You will have to provide the caliber and whether it is pump or CO2 powered.
co2, nitrogen and oxygen
From 1990-1996 Daisy made the model 990 that was multi-pump and C02.
Nitrogen is the most present gas in air. It sits at about 78% nitrogen, 21% oxygen and 1% other gases (which include CO2)
Yes, they require High pressure air (nitrogen) tanks. They cannot run off of CO2.
A compound for air is carbon dioxide (CO2), which is one of the gases present in the atmosphere along with nitrogen, oxygen, and other trace gases.
