Common Terminology for Airsoft

In airsoft, the common words you hear will be "hop up", "fps", "rps or rpm", etc.(I'll let you know more on the etc) What do these words mean?
"Hop up" means the device that changes the direction of bb that flies out of the gun. You can only adjust the hop up to go up or down. The main point of hop up is to make the bb go straight instead of up or down and to increase accuracy.


As shown in this diagram of a M4/M16 , the hop up adjuster is above (its supposed to be above but to the side of the inner barrel) and the hop up chamber is right above it as well. When the dial is turned right, it increases the hop up meaning the hop up chamber goes down. When you fire the bb out, the rubber padding will touch the bb therefore making the bb go straight and give little more accuracy.
Keep adjusting it and firing it until you see the bb go straight. If you turn the dial all the way to the right (increasing too much hop up) the gun will break because the hop up chamber will be basically blocking the bb's path.


Fps means feet per second and is commonly used to see how much kick it gives. The higher the fps, the faster the bb will exit out of the barrel and hitting the target real hard.
Rps or Rpm means Rate per second or minute and determines how many bbs come out in each second or minute. Rps or Rpm is used for guns that have a full auto feature.


To determine the Fps and Rps(m) airsofters use a chronograph that calculates the how fast and how many bbs exit out of your gun.

Another terminology is "Field-Stripping" which means to take apart your gun WITHOUT using tools. CQB means Close Quarter Battle as opposed to Woodland meaning you have a skirmish (battle) in the woods or any open area.
