A BB, which stands for “ball bearing”, is a spherical projectile used in airsoft guns and BB guns. The size of a BB is measured by its diameter, which is the distance of a straight line passing through the center of the BB and connecting two points on its circumference. The most common BBs used today are 6mm and 8mm in diameter.
What Does the Size of a BB Mean?
The size of a BB affects its performance in various ways. Smaller BBs have greater accuracy than larger ones, since they are less affected by wind and gravity. However, smaller BBs also have less range, since they are less affected by the air resistance. Additionally, the size of the BB affects the rate of fire, since larger BBs require more energy to propel.
How is the Diameter of a BB Measured?
The diameter of a BB is usually measured in millimeters (mm). To measure the diameter of a BB, use a caliper or a ruler to measure the distance between two points on its circumference. For example, a 6mm BB has a diameter of 6mm, while an 8mm BB has a diameter of 8mm.
What is the Most Common Diameter for a BB?
The most common diameter for a BB is 6mm. This size is widely used in airsoft guns and BB guns, as it offers a good balance between accuracy, range, and rate of fire. 8mm BBs are also becoming increasingly popular, as they offer greater range and rate of fire, but at the cost of accuracy.
Do Different Types of Guns Require Different Diameters of BBs?
Yes, different types of guns require different diameters of BBs. For example, airsoft guns typically use 6mm or 8mm BBs, while BB guns typically use 4.5mm or 5.5mm BBs. Additionally, some guns require special BBs, such as biodegradable or tracer BBs.
Are There Other Sizes of BBs?
Yes, there are other sizes of BBs available, such as 4.5mm, 5.5mm, 0.12g, 0.2g, and 0.25g. These BBs are typically used in BB guns, as they offer greater accuracy and range. Additionally, some BB guns are designed to use special BBs, such as biodegradable or tracer BBs.
Are All BBs Compatible With All Guns?
No, not all BBs are compatible with all guns. For example, an airsoft gun typically requires 6mm or 8mm BBs, while a BB gun typically requires 4.5mm or 5.5mm BBs. Additionally, some guns require special BBs, such as biodegradable or tracer BBs. It is important to check the specifications of your gun before purchasing BBs for it.

Is size the only factor to consider when selecting a BB?
No, size is not the only factor to consider when selecting a BB. Other factors to consider include the type of gun you are using, the distance you are shooting, and the type of BB you are using (biodegradable or tracer).
Are there any safety considerations when using BBs?
Yes, there are safety considerations when using BBs. Always wear safety glasses and other protective gear when using airsoft or BB guns. Additionally, never shoot at people or animals, and always respect property rights and local laws.
Can I use a BB in a real firearm?
No, you should never use a BB in a real firearm. BBs are designed to be used in airsoft and BB guns only.
Can I reuse BBs?
No, you should never reuse BBs. Always use new BBs when shooting airsoft or BB guns.
Are there any special considerations when storing BBs?
Yes, you should always store BBs in a cool, dry place away from direct sunlight. Additionally, you should keep them out of reach of children.
