How to Choose the Right Plastic BBs for Airsoft

Plastic BBs are small, round pellets used in airsoft, BB, and paintball guns. These pellets come in various sizes and materials, each with unique properties and purposes. 

Plastic BBs have become exceptionally popular because they’re cheap, easy to find, and convenient. 

This post covers the several types of plastic BBs that you can use, their differences, and what they’re best suited for. We’ll also give you some quick tips on selecting the right pellets for your gun. 

Types of plastic BBs

  1. Acrylonitrile-butadiene-styrene, or simply ABS, is a pervasive plastic used in manufacturing plastic BBs. It is a lightweight and impact-resistant thermoplastic polymer that is excellent for airsoft guns and BB guns. ABS plastic BBs are also reasonably priced and widely available. They are appropriate for both indoor and outdoor use.
  1. If you are looking for more soft pallets, then Polystyrene bbs are the most common. This material is very flexible, like rubber. This is why it is readily used to make paintball pellets. Polystyrene BBs are lightweight and cheap and are often used in training.
  1. Another thermoplastic polymer frequently used to create plastic BBs is PP or polypropylene. It is known for having a high melting point and being impact- and corrosion-resistant, making it appropriate for use in BB and airsoft weapons.
  1. Biodegradable BBs are made to break down over time. Typically, materials like polylactic acid (PLA) or thermoplastic obtained from renewable resources like corn or potatoes are used to make these BBs. Therefore, plastic pellets are frequently utilized in outdoor games.

Common BB sizes

The common BB sizes are 6mm, 8mm, and 12mm. The kind of gun you’re using and the intended use will determine the size of the BBs you use.

The most popular size is the 6mm plastic BB. They are utilized in paintball, BB, and airsoft guns. They are perfect for rapid-fire and high-speed shooting because they are lightweight and compact. The weight of these BBs varies between 0.12g and 0.43g. They can be used both inside and outside.

8mm BBs are slower but more powerful than 6mm BBs due to their size and weight. The weight of these BBs varies between 0.2g and 0.5g.

The largest plastic BB size, 12mm, is most frequently used in paintball guns. They are more accurate at greater distances because they are heavier than 6mm and 8mm BBs. They weigh between 0.8g and 1.2g.

Choosing the right plastic BB

While purchasing plastic BBs, several things need to be taken into account. The type of gun is the first factor. When making a purchase, it is crucial to review the manufacturer’s recommendations because different firearms require different kinds of BBs. 

The type of game is the second thing to take into account. Selecting the appropriate weight for your game is essential because some games may call for heavier or lighter BBs.

BBs are typically weighed in grams. The most popular weights are 0.20g, 0.25g, and 0.30g. The accuracy and performance of the BB are significantly impacted by its weight. 

Heavier BBs are more accurate for extended distances because they are more stable in flight. However, they may not be as fast as lighter BBs. Lighter BBs, on the other hand, are faster, but they are less stable and less accurate over long distances.

When selecting the best plastic BB, you must consider the game type and the gun’s FPS (feet per second). Lighter BBs are best for short-range games, such as close-quarter combat. Heavier BBs are more suitable for outdoor games where you’ll shoot more at long distances. 

Quality and safety plastic BBs

Using high-quality plastic BBs is crucial for safety reasons. Poor-quality BBs can shatter or break apart inside the gun, causing damage or injury. Always check for defects, such as warping or cracks, and verify the manufacturer’s information to ensure quality. Avoid using BBs that are dirty, damaged, or have been exposed to moisture.

Several organizations, such as the Airsoft International Tactical Training Center and the Airsoft Safety Foundation, have developed standards for airsoft BBs. These standards specify the materials, weight, and size of BBs and their performance characteristics. Following these standards can help ensure the quality and safety of BBs.


Plastic BBs offer a safe and convenient alternative to traditional ammunition for those who enjoy shooting sports and training exercises. With various sizes, weights, and materials available, a plastic BB is suitable for almost every gun and game type

Choosing the right plastic BB for your gun is crucial for optimal performance and safety. By understanding the different types of plastic BBs available, you can make an informed decision when purchasing them. 

Whether you’re a beginner or an experienced shooter, plastic BBs allow for an affordable and enjoyable way to practice your skills and have fun with friends.
