Airsoft is a pretty "point and shoot" type of sport. All you need to start playing is eye protection, an airsoft gun, and a magazine full of airsoft BBs for ammunition. First, off let's talk about what airsoft BBs are. Airsoft BBs are used as ammunition in airsoft guns which are similar to paintball guns. Instead of paint, they shoot little plastic pellets or "BBs". These plastic pellets are used for target practice or to safely tag other airsoft players in force-on-force team matches and games. Safety is a top priority while playing airsoft and each airsoft player must wear eye protection!
Have you ever wondered about the types of airsoft BBs, how they are made, and which ones to use? Did you know that airsoft BBs come in all different weights, qualities, and colors? If you did, great! If you didn't, then you have come to the right place! Picking the right type of airsoft BB can help you play better on the airsoft field!
Airsoft BB Size and BB Manufacturing Process
All standard airsoft BBs are 6mm in size. However, some airsoft BBs also come in an 8mm size. The BB millimeter size is the approximate measurement of the diameter of the airsoft BB pellet. These sizes allow them to be shot out of most spring airsoft guns, automatic-electric-gun (AEG) airsoft guns, or gas powered airsoft guns.
Airsoft BBs are made using a plastic molding process. In short, the airsoft BB manufacturing process is made up of material selection, sorting, melting, material injection, polishing, and packaging. We'll talk more about the airsoft BB manufacturing process later.
How Bio Airsoft BBs Are Made: The Airsoft BB Manufacturing Process From Plastic to Playing
The High Speed Manufacturing Difference
Look for high-quality airsoft BBs which are specially made with a seamless plastic molding process. This type of airsoft ammo is usually manufactured with injection molding, has a spherical bearing BB design, and is molded so the airsoft BBs are completely seamless. Then, the airsoft BBs are double polished to ensure that every 6mm BB is 5.95mm +/- 0.1mm in diameter and perfectly round.
Airsoft BB Size and Airsoft Gun Barrel Accuracy
The airsoft BB size allows it to fit perfectly into airsoft gun barrels. The inner gun barrel diameter is just slightly bigger than the BB size. That way when the BB is fired, less air can escape around the BB and more air pushes the BB out of the barrel. The feet-per-second (FPS) performance rate of the airsoft BB is increased as a result.
FPS is the term which tells you how fast airsoft guns shoot a BB. It's similar to rate of fire (ROF) which includes rounds per minute (RPM) and rounds per second (RPS). These two terms define how many BBs an airsoft gun can shoot in a minute or second. Most airsoft fields have FPS limits, so be sure to check with field staff when playing airsoft.
Airsoft guns can also be upgraded with tighter barrels or "tight bore barrels" to increase the FPS. For example, many AEGs which shoot 6mm BBs usually come with a 6.08mm barrel. The barrel can be upgraded to a 6.01mm or 6.03mm tight bore barrel for better tolerances and performance which allow less air to escape around the airsoft BB when it is fired.
The High Speed Measurement Difference
Since high-quality 6mm airsoft BBs are 5.95mm +/- 0.1mm and perfectly round, an upgraded barrel means the BB has just the right fit inside the barrel with only about 0.07mm room to spare. This helps your airsoft BBs go farther faster!
Airsoft BB Weight
Airsoft BBs come in a few standard weights. The most common weights are 0.12 gram and 0.20 gram BBs. Other common weights are 0.25 gram, 0.28 gram, 0.30 gram, and up to 0.40 gram BBs. The weight of the airsoft BB affects how much force is needed to propel the BB out of the airsoft gun and direct its flight path after the BB is fired.
Lighter airsoft BBs, like 0.12 gram BBs, are usually designed for closer range targets. They are typically used in spring powered airsoft guns which fire them at about 250 FPS. These BBs are hollow internally and are the most accurate at close ranges. They are not recommended for use in airsoft guns with higher FPS because they can shatter causing damage to the airsoft gun and are almost completely ineffective and inaccurate at longer ranges.
Mid-range airsoft BB weights, like 0.20 gram to 0.28 gram BBs, are the "middle of the road" for airsoft BBs. These BBs have the widest use range because they are light enough to be used in airsoft guns with lower FPS at close range and strong enough to be used in airsoft guns with higher FPS at longer ranges. However, their flight paths are not as stable as heavier BBs for extreme long range usage.
Heavier airsoft BBs, like 0.30 gram to 0.40 gram BBs, are designed for the highest flight stability and longest range. They are most often used in high powered AEGS and airsoft sniper rifles. More force is needed to fire these heavier BBs, and they are more stable and accurate during flight because of it.
The High Speed Weight Difference
You can find airsoft BBs on online in many common sizes and weights including both 6mm and 8mm diameters and 0.20 gram, 0.25 gram, 0.28 gram, and 0.32 gram weights. These BB weights can be used in most airsoft guns and are accurate from short to long ranges with great stability. This allows players to choose the best BB weight for them in any airsoft game.

Airsoft BB Material and Manufacturing Quality
Airsoft BBs are only as good as the material they are made out of. There are lots of details to think about when it comes to BB quality, but there are a few very important things to know. We'll cover the basics here! There are two very common types of BB materials available to airsoft players, non-biodegradable airsoft BBs and biodegradable airsoft BBs.
Non-biodegradable Airsoft BBs
Non-biodegradable airsoft BBs are usually made from a plastic called acrylonitrile butadiene styrene (ABS). ABS plastic is chemically constructed from a compound with a molecular formula of (C8H8•C4H6•C3H3N)n.
ABS airsoft BBs are the cheapest, do not significantly degrade over time, are not really environmentally friendly, and are not water soluble. Because of this, many outdoor airsoft fields do not allow players to use these non-biodegradable airsoft BBs since they will literally be in the ground where they fall for a long time. However, ABS BBs are suitable for indoor use where they can be easily collected or cleaned up or on private property with the owner's consent.
Biodegradable Airsoft BBs
Biodegradable airsoft BBs (a.k.a "bios") are usually made from a plastic called polylactic acid or polylactide (PLA). PLA plastic is constructed from natural resources and renewable materials including corn products and certain starches with a molecular formula of (C3H4O2)n.
PLA airsoft BBs cost more than ABS BBs but are environmentally friendly, are more water soluble than ABS BBs, and break down into water and carbon dioxide in about 47 to 90 days in industrial recycling facilities or a bit longer under the right environmental conditions outdoors. Most outdoor airsoft fields require players to use these types of biodegradable airsoft BBs.
The High Speed Material Difference
Use biodegradable airsoft BBs which are made of PLA plastic material. This helps keep the playing fields and earth cleaner! When shopping for airsoft BBs, look for airsoft BBs are only made from PLA plastic or marked as "bios". These types of airsoft BBs are biodegradable and leave a minimum signature behind when played with. You can do your part to keep the earth as clean as possible keep the Earth green and plastic free. Please join our efforts to keep airsoft fields the way we found them by using biodegradable BBs.
Airsoft BB Colors
Airsoft BBs come in all kinds of colors. The color of the BB increases or decreases its visibility while in the air. This can increase a player's tactical advantage significantly since other players cannot see where the BBs are being fired from, but there are some downsides.
White and lighter colored airsoft BBs are the most popular. These BBs are fairly easy to see after being fired and while they are mid-flight in the air. A few positive things about using these lighter BBs are that the shooters can easily place shots by visually tracking the fired airsoft BBs and airsoft field referees can call "dead" airsoft players out more easily after seeing them hit with the BBs. A downside is that targets can usually tell which direction the BBs are coming from and know the general area where the other airsoft player is hiding.
Darker and black colored airsoft BBs are harder to see because their color blends into the surroundings more. An advantage of these BBs is that they are less easily seen by targets while in the air mid-flight. A few downsides of these darker colored airsoft BBs are that the airsoft gun shooter may not be able to check his shot placement by sight and airsoft field referees cannot see the BBs hit players.
The High Speed Color Difference
If you are just starting out playing airsoft look for white airsoft BBs. These are the easiest to find and play with. Lighter colored BBs have become the airsoft industry standard and are available at many airsoft retail stores and also online.
