It is actually a fairly simple air system. The air travels from the tank, through the ASA, to the line and up to the regulator. The air through stock just makes the line look a bit better.
By Nitrogen I am taking it that you mean compressed air and as long as the tank is high pressure it should work fine.
Yes it can be.
An air through stock is usually where the guns stock is your gas tank, making the military sim look more authentic
There are many different types out there; folding air though, fixed, telescoping to name a few. Take a look around and find what works the best for you.
Yes, you always need a tank. The Air-thru stock allows you to run a remote coil from the back of the stock instead of the ASA.
Not if you're using a co2 tank.
On a post 1995 stock Buell, no, a Sportster air filter will not fit. On the older tube frame Buells, you may adapt an air cleaner system that will accept a stock Sportster air filter.
The thermostat tells the air conditioner to pull in air. The air then goes through cooling lines in to the house. goes through the vents and out through the registers in the rooms of the house.
As of Jan 7, the price for the Air Canada Stock is $2.55.
Through air
It should. I have a real m4 stock on one of my guns at the moment. just make sure that the stock is compatible with your setup. different companies offer different set ups. the stock should fit it though
Heaters work best set on floor allowing the hot air to rise through the car and heat more air.
