One of the main differences between a BB gun and an airsoft gun is the type of ammunition that they will have. For example, you can expect that a BB gun will be firing small metal ammunition. Airsoft guns, on the other hand, will be using plastic projectile ammunition.
This means that you can expect that they will be safer when you want to use them for games. This explains why there are some places wherein you would be using Airsoft guns especially when you are playing with other teams.
People are not recommended to use BB guns when they are just playing around because they would only end up hurting other people in the process.
Airsoft is a popular recreational activity that allows the participates to five plastic pellets or projectiles at each other using firearms that look like toy guns. The game originated in Japan, but it spread to other parts of the world, and even the military took up airsoft guns for training purposes.
The plastic pellets are not hard enough to hurt or injure a player, but the speed of the projectile is still impressive. BB guns are not toys, and they are used to shoot hard pellets that are made of steel or lead with either zinc or copper plating to resist corrosion.
They are mostly used for hunting birds. BB guns usually measure 4.3 to 4.4 mm in diameter and .033 to .035 in weight. BB guns should not be used in an Airsoft game in place of an Airsoft gun.
