An air gun is usually a replica of a real firearm that is powered by air or C02 that is used to fire a projectile (Pellet or BB). Only air or C02 is used in the air gun. Whereas a firearm uses gunpowder to fire a bullet. Air guns are powerful but not a powerful as a real firearm.
Only if the airgun has a scope rail designed into the gun. You will also need an airgun scope not a firearms scope.
The highest velocity of an airgun is that of Evanix AR6 pistol which is 1000 fps.
