Airsoft guns have become increasingly popular among recreational shooters, tactical training enthusiasts, and competitive players. Whether you are new to the hobby or considering buying your first airsoft gun, one of the most common questions is: What do airsoft guns shoot? Understanding the ammunition used in airsoft guns is important for safety, performance, and choosing the right equipment.

What Do Airsoft Guns Shoot?

Airsoft guns primarily shoot small spherical projectiles known as BBs. Unlike traditional firearms that use metal bullets, airsoft guns fire lightweight plastic pellets specifically designed for recreational shooting and airsoft games. These BBs are engineered to provide a realistic shooting experience while reducing the risk of serious injury when proper safety gear is used.

The standard airsoft BB measures 6mm in diameter, although some specialty airsoft guns use 8mm BBs. Most players and airsoft fields prefer 6mm ammunition because it is compatible with the majority of airsoft guns available today.

What are Airsoft BBs Made of?

Airsoft BBs are commonly made from durable plastic materials. Standard plastic BBs are widely used for target shooting, backyard practice, and indoor airsoft games. Their smooth surface helps ensure reliable feeding and consistent performance.

In recent years, biodegradable BBs have become increasingly popular. These environmentally friendly BBs are designed to break down naturally over time, making them ideal for outdoor airsoft fields and woodland games. Many airsoft venues now require players to use biodegradable ammunition to minimize environmental impact.


Understanding Airsoft BB Sizes

The most common airsoft BB size is 6mm, which is used in nearly all modern airsoft guns. These BBs are available in different weights and quality grades to suit various shooting needs.

Some specialty airsoft guns use 8mm BBs, but they are far less common. Since 6mm BBs are widely available and supported by most manufacturers, they remain the standard choice for airsoft players around the world.

Different Airsoft BB Weights

One of the most important factors affecting performance is BB weight. Airsoft BBs are available in a variety of weights, including:

  • 0.12g
  • 0.20g
  • 0.25g
  • 0.28g
  • 0.30g
  • 0.36g
  • 0.40g and heavier

Lighter BBs travel faster but are more easily affected by wind and obstacles. Heavier BBs generally provide better stability, improved accuracy, and greater consistency at longer distances.

For most beginner players, 0.20g and 0.25g BBs offer an excellent balance between speed and accuracy. Advanced players often choose heavier BBs for upgraded rifles and sniper platforms.

How Do Airsoft Guns Shoot BBs?

Airsoft guns use different power systems to launch BBs toward a target. Regardless of the system, the goal is the same: generate enough force to propel the BB through the barrel accurately and consistently.

When the trigger is pulled, compressed air or gas pushes the BB through the barrel. The velocity of the BB is typically measured in feet per second (FPS), which helps determine the gun’s performance and field legality.

Types of Airsoft Gun Power Systems

  • Spring-Powered Airsoft Guns

Spring-powered airsoft guns require the user to manually cock the gun before each shot. These guns are simple, reliable, and affordable, making them a popular choice for beginners and casual shooters.

  • Gas-Powered Airsoft Guns

Gas-powered airsoft guns use compressed gases such as green gas, propane, or CO2. These guns often provide realistic recoil and a more authentic shooting experience. Gas-powered pistols are particularly popular among airsoft players.

  • Electric Airsoft Guns (AEGs)

Automatic Electric Guns, commonly known as AEGs, use rechargeable batteries and electric motors to fire BBs. These are among the most common airsoft guns because they offer reliable performance, semi-automatic and automatic firing modes, and easy customization options.

Do Airsoft Guns Shoot Metal BBs?

A common misconception is that airsoft guns shoot metal BBs. In standard airsoft gameplay, they do not. Airsoft guns are specifically designed to use plastic or biodegradable BBs.

While some specialty products may use metal projectiles, these are not considered standard airsoft ammunition and are generally prohibited at organized airsoft events. Metal BBs can damage airsoft gun components and significantly increase the risk of injury.

Airsoft BBs vs BB Gun Ammunition

Many people confuse airsoft guns with traditional BB guns. However, the two are very different. BB guns typically shoot steel BBs or lead pellets and operate at much higher power levels. Airsoft guns, on the other hand, shoot lightweight plastic BBs and are designed primarily for recreational gaming, tactical simulations, and training exercises. Because of these differences, airsoft guns are generally considered safer for organized gameplay when proper protective equipment is used.

How Far Can Airsoft BBs Travel?

The distance an airsoft BB can travel depends on several factors, including:

  • BB weight
  • Gun power
  • Barrel quality
  • Hop-up settings
  • Weather conditions

Most standard airsoft guns can effectively engage targets at distances between 100 and 200 feet. High-performance rifles and sniper setups may achieve greater effective ranges when paired with heavier BBs and proper tuning.

What is Hop-Up and Why is it Important?

The hop-up system is one of the most important features of an airsoft gun. It applies backspin to the BB as it leaves the barrel. This backspin creates lift, allowing the BB to travel farther and maintain a flatter flight path. Proper hop-up adjustment can significantly improve accuracy and range without increasing the gun’s power output. Many experienced players spend time fine-tuning their hop-up settings to match their preferred BB weight and shooting style.

Airsoft Safety Considerations

Although airsoft BBs are made from plastic, they can still cause injuries if used irresponsibly. Safety should always be the top priority during gameplay and target practice. Protective eyewear is essential and should never be removed while on an active field. High-quality goggles designed for airsoft use help prevent serious eye injuries. Additional protective equipment may include:

  • Face masks
  • Gloves
  • Long sleeves
  • Tactical clothing
  • Knee and elbow protection
  • Following field rules and maintaining safe shooting distances can further reduce the risk of injury.

Choosing the Right BBs for Your Airsoft Gun

Selecting quality BBs can have a major impact on performance. Poor-quality BBs may contain imperfections that cause feeding issues, inaccurate shots, or internal damage. When choosing airsoft ammunition, consider:

  • BB weight
  • Material type
  • Manufacturer reputation
  • Biodegradable requirements
  • Intended use
  • Premium-grade BBs offer better consistency, improved accuracy, and more reliable operation compared to low-cost alternatives.

Enjoy Playing Airsoft Safely!

Airsoft guns shoot lightweight plastic or biodegradable BBs specifically designed for recreational shooting and airsoft games. These BBs typically measure 6mm in diameter and are available in a wide range of weights to suit different airsoft guns and playing styles.

Understanding BB types, weights, power systems, and safety practices can help you choose the right equipment and improve your overall airsoft experience. Whether you are a beginner or an experienced player, using high-quality BBs and following proper safety guidelines will ensure better performance and more enjoyable gameplay.
