Sorry I'm a little late to the party. I worked for a manufacturing company that had a lot of automated assembly systems containing lots of pneumatic slides, cylinders, etc. for motion. The company would have loved to run nitrogen in their pneumatics if it were affordable. They considered nitrogen to be the gold standard for pneumatics for its cleanliness and freedom from moisture. There's nothing wrong with using nitrogen in an air gun except for the cost.
