Some airsoft guns shoot very high RPMs which can increase into the thousands of BBs shot per minute. These two terms define how many BBs an airsoft gun can shoot in a minute or second. It's similar to rate of fire (ROF) which includes rounds per minute (RPM) and rounds per second (RPS). The feet-per-second (FPS) performance rate of the airsoft BB is increased as a result.įPS is the term which tells you how fast airsoft guns shoot a BB. That way when the BB is fired, less air can escape around the BB and more air pushes the BB out of the barrel. The inner airsoft gun barrel diameter is just slightly bigger than the BB size. This is important for the accuracy of the airsoft gun and the flight stability of the airsoft BB. The airsoft BB size allows it to fit perfectly into airsoft gun barrels. Novritsch is a airsoft BB manufacturer which specializes in making high quality airsoft sniper BBs.

For now, check out the video below by Novritsch to see how airsoft BBs are made as Christoph Neuwirth, Novritsch CEO, tours the airsoft BB factory. We'll talk more about the airsoft BB manufacturing process later. In short, the airsoft BB manufacturing process is made up of material selection, sorting, melting, material injection, polishing, and packaging. These sizes allow them to be shot out of most spring airsoft guns, automatic-electric-gun (AEG) airsoft guns, or gas powered airsoft guns.Īirsoft BBs are made using a plastic molding process. The airsoft BB millimeter (mm) size is the approximate measurement of the diameter of the airsoft BB pellet. You usually know if your airsoft gun shoots 8mm airsoft BBs. This makes these larger BB sizes harder to use in longer range airsoft guns.

The larger 8mm size of the airsoft BB creates more air resistance around the BB as it travels through the air. These larger airsoft BBs are predominately used in specialty airsoft pistols like revolvers and other close range weapons. However, some airsoft BBs also come in a larger 8mm airsoft BB size. If you have questions about what airsoft BB size your airsoft gun accepts, check in your airsoft gun owner's manual, look for markings on the airsoft gun magazine, or check online by looking up the model number and manufacturer of the airsoft gun. Your airsoft gun is most likely a 6mm airsoft gun. If you are unsure what size BB your airsoft gun shoots, look for 6mm airsoft BBs. This is because most airsoft guns like pistols, rifles, sniper rifles, and squad support airsoft guns have magazines which accept 6mm airsoft BBs and also have 6mm airsoft gun barrels. All standard airsoft BBs are 6mm in size.
