What FPS is Good in Airsoft : Ehobby Guide

FPS in airsoft stands for "feet per second," and it refers to the velocity of an 0.2g 6mm BB (plastic projectile) that is fired from an airsoft gun.  FPS is an important metric in airsoft as it affects the range, accuracy, and impact of the BB.  It is also often used by law enforcement to determine if an airsoft gun shoots below the legal limit in any particular legal jurisdiction.  Mind you, the legal power limits of airsoft guns varies greatly from country to country.

Most airsoft fields have a limit on the FPS of the guns that can be used on their premises. This limit is usually set to ensure the safety of players and prevent injury. The limit can vary depending on the field, but it is often around 350-400 FPS for automatic electric guns (AEGs) and 450 FPS for bolt-action sniper rifles.  For indoor sites, FPS limits can be below 320fps, which translates to 1 joule of power.

It's important to note that while FPS is important, it's not the only factor that determines the performance and range of an airsoft gun. The quality of the gun's internal components, the weight and quality of the BBs used, and the hop-up system can all affect the gun's accuracy and range.

What does Airsoft FPS Affect?

The FPS (feet per second) of an airsoft gun can affect several aspects of its performance, including:

Airsoft Gun Effective Range

Generally, a higher FPS will result in a longer effective range for the BB. This is because a BB fired at a higher velocity will have more energy to fly a greater distance.  However, other factors such as wind and the weight of the BB can also affect range.  Airsoft guns equipped with a hop up will also allow the BB to fly farther.  Typically with airsoft guns that are rated with a high FPS, use a heavier BB.

Impact

A BB fired from a gun with a higher FPS will have more kinetic energy and therefore will hit with greater force. This can be desirable for players looking for a more realistic experience or for those using heavier BBs that require more energy to maintain their momentum.

Safety

FPS is also an important factor in ensuring the safety of airsoft players. Most airsoft fields have specific rules about FPS limits for different types of guns to prevent injury. A gun firing BBs at too high of an FPS can cause serious harm to a player if they are hit at close range or without proper protective gear.

Contrary to popular belief, having a higher FPS does not improve accuracy but may actually reduce it, unless much heavier BBs are used to make sure of the extra energy.  Using a light 0.2g BB with a high power gun might actually make the BB fly all over the place due to the extra turbulence that is caused by the inevitably bigger volume and higher compression of air leaving the barrel.

What is the Ideal FPS for Airsoft?

The ideal FPS (feet per second) for airsoft depends on several factors, including the type of gun being used, the weight and type of BBs being fired, and the rules of the specific airsoft field or event.

In general, most airsoft fields and events have specific airsoft FPS limits for different types of guns, which are designed to ensure safety and prevent injury. These limits can vary depending on the field, but they are typically around 350-400 FPS for automatic electric guns (AEGs) and 450 FPS for bolt-action sniper rifles.

It's important to note that exceeding these limits can lead to serious injury, and most airsoft fields will have strict rules and procedures in place to enforce these limits.

Additionally, the ideal FPS for an airsoft gun can vary depending on the player's individual needs and preferences. For example, a player who primarily plays in indoor environments may prefer a gun with a lower FPS that is more maneuverable, while a player who plays in large outdoor fields may prefer a gun with a higher FPS that can reach targets at longer distances.

Ultimately, the ideal FPS for airsoft depends on a variety of factors and can vary depending on the specific situation and player preferences. It's important for players to understand the FPS limits of their airsoft field or event and choose a gun that fits their individual needs and play style.

Is a Higher FPS Always Better?

No, a higher FPS (feet per second) is not always better in airsoft. While a higher airsoft FPS can provide some advantages, such as longer range and increased accuracy, it can also have drawbacks.

One drawback of a higher FPS is that it can increase the risk of injury. If a BB fired from an airsoft gun exceeds the FPS limit set by the field or event, it can cause serious harm to other players who are hit at close range or without proper protective gear.

Another drawback of a higher FPS is that it can reduce the lifespan of the gun's internal components. When a BB is fired at a higher velocity, it places more stress on the gun's gearbox, motor, and other components, which can cause them to wear out more quickly.

Additionally, a higher FPS can make the gun more difficult to handle, especially for players who are new to airsoft or who prefer a more lightweight and maneuverable gun.

Ultimately, the ideal FPS for an airsoft gun depends on a variety of factors, including the type of gun, the weight and type of BBs being used, and the rules of the specific airsoft field or event. While a higher FPS can provide some advantages, it's important to consider the potential drawbacks and choose a gun with an appropriate FPS for your individual needs and play style.

What FPS Causes Damage to Skin?

Any FPS (feet per second) that exceeds the limits set by the airsoft field or event can cause damage to the skin. This is why most airsoft fields have strict rules and procedures in place to enforce these limits and ensure the safety of players.

The exact FPS that can cause damage to the skin can vary depending on factors such as the distance between the shooter and the target, the type of BB being used,the protective gear worn by the target, and of course the skin.  Typically we find that getting shot with a 350fps BB at close range will cause a serious welt and possibly some minor bleeding.  Getting shot by a 400fps BB at close range can break skin and cause a small circular blood wound.  The above assumes getting shot on bare skin.  Having some clothing covering the skin can greatly reduce injuries, especially thicker clothing like a sweatshirt.  For winter games, players may wear multiple layers of clothing and in these instances, it may be even difficult to feel the shot despite getting it.  In other words, airsoft plastic BBs are low energy enough that they do not penetrate clothing much. 

That’s why it is wise to cover all areas of your body before you engage in an airsoft firefight.  Use eye protection, a full face mask to protect your face and teeth, and long sleeved shirts and pants.  If you want to be extra careful, wear a hat or helmet, and have something to cover up your neck.

Final Remarks

It's important to note that while FPS is an important factor in airsoft, it's not the only factor that determines the performance of an airsoft gun. Other factors such as accuracy, range, and consistency also play a crucial role.  More is not always better.

It's also essential to emphasize that safety should always be the top priority in airsoft. Players should always wear appropriate protective gear, such as eye and face protection, and adhere to all safety rules and regulations set by the field or event organizers.

In conclusion, while FPS is an essential factor in airsoft, it's not the only determining factor. Players should always prioritize safety and follow the guidelines set by the field or event organizers.
