What Does FPS Mean in Airsoft?
FPS is an acronym for "feet per second" and is a way of determining the speed of the BB when shot out of your Airsoft gun. It’s the most common way of determining the velocity of an Airsoft gun. FPS depends on the power of the Airsoft gun and the weight of the BB. .20 gram BBs are the standard on the field and it is what we use at Hobbytron when determining FPS of most Airsoft guns. Most lower end Airsoft guns fire around 200 FPS while their more fancy brethren usually clock around 400 FPS. To give some perspective, shooting a BB at 145 FPS means the BB is traveling around 100 mph!
To measure your Airsoft gun’s FPS you are going to need a chronograph, which is similar the police’s radar gun. To can buy them online, but you can also find them at most Airsoft fields and some Airsoft specialty stores.
I can’t stress enough that you shouldn't buy a gun just because it has an insanely high FPS. Quality, performance and accuracy are way more important factors to consider when purchasing an Airsoft gun. Furthermore to prevent needless injury, most Airsoft fields have a FPS limit on the Airsoft guns allowed on the field. If you have an Airsoft rifle with an insane FPS, you may want to use heavier BBs (like .25g or .27g BBs) on the field to get a lower legal FPS. Heavier BBs also have a higher stopping power and accuracy which is perfect for snipers. .12 gram BBs are fine for inexpensive spring Airsoft guns but are not used by serious Airsoft players. They are also usually lower quality and can break inside your Airsoft gun damaging it.
