How Airowguns are different
Airowguns don't use CO2 or compressed air, just elbow grease. Since you won't be firing shots off without a care, you'll go through less paint, so an Airowgun is easily the cheapest way to play paintball, though the marker itelf is more expensive than some entry-level guns.
Airowguns are designed to let you control the velocity, to make sure you get the same range and speed you would with any other paintball gun, while still playing safely. The best part, Airowguns are nearly silent, letting a paintball archer weave through the field, picking their shots and picking off opponents.
Your opponents might think they're the Predator, but you'll show them they're your prey with an Airowgun.
