FPS in Airsoft What Does it Mean

What Does FPS Mean in Airsoft?

A simple definition of FPS in terms of airsoft is that it stands for feet per second or feet per second rate. This measure of velocity is used to denote the speed at which a particular airsoft gun can fire one of its BBs, or 6mm plastic pellets, from its muzzle. If you're an airsoft enthusiast, understanding FPS is important as it stands as the definitive element in verifying the capabilities of your gun.

What FPS do I Need for airsoft?

When it comes to how much FPS you should opt for, that can be somewhat subjective. Looking at the rules outlined by the organization running the airsoft event or game you are going to be participating is the best way to gauge the minimum FPS of your airsoft gun. Airsoft fields often place restrictions on the minimum FPS of guns allowed. Generally, for automatic electric guns (AEGs) that are semi-automatic, the minimum FPS needed is around 300 fps. For spring-powered airsoft guns, the range is typically a bit lower and runs from 200 to 250 fps.

Factors to Consider for FPS:

There are several factors that should be considered when looking for an airsoft gun with the FPS you need. Here are a few of the key elements to look for:

Polymer vs Metal Bodies

The materials used to craft the body of your pistol or rifle of choice are of great relevance to FPS capabilities. Polymer, which is a plastic variant, is the most popular choice among airsoft gun manufacturers. Polymer bodies are lighter than the metal varieties, so they tend to shoot out BBs a bit faster. Metal body construction, on the other hand, is much more dense and heavy, and as a result, results in lower FPS.

Inner Barrel Length

The length of the inner barrel is a critical component in determining how much velocity your gun can fire off. Generally speaking, the longer the inner barrel is the more velocity you will experience. This is due to the amount of space it takes for the compressed air generated by the gun to expand and propel your pellet to its maximum speed.

Motor Quality

The power and performance of the motor of your gun will also affect the FPS of your gun. A quality motor is essential for achieving the ultimate velocity you are looking for. Motors with higher power ratings tend to generate more energy, leading to increased FPS.

FPS and Accuracy

Obviously, a high FPS rate in airsoft equates to more accuracy, as the higher the velocity of the BB, the less aerodynamic drag it will experience and the likelier it is to fly in a straighter direction. That said, the amount of accuracy you will experience at any given FPS really is highly individual and dependent on your individual shooting style and quality of the gun you are using.

Brief Recap

Understanding the concept of FPS in airsoft is important when it comes to selecting the right gun for you. FPS stands for feet per second or feet per second rate and refers to the speed at which a particular airsoft gun can fire one of its BBs, or 6mm plastic pellets, from its muzzle. Generally, for automatic electric guns (AEGs) that are semi-automatic, the minimum FPS needed is around 300 fps, while for spring-powered airsoft guns, the range is typically a bit lower and runs from 200 to 250 fps. Factors such as materials used for the body of your gun, barrel length, motor quality all factor into in the FPS of your gun. Accuracy in shooting with airsoft guns also generally goes hand-in-hand with FPS, though ultimately an individual shooter's skill will also come into play.
