What are the stats for BB guns and what do they mean?

Answer 1

I assume you are asking about BB guns NOT air soft guns.

Here are a few simple stats for BB guns.

FPS: Feet Per Second. This tells you how fast the BB or Pellet travels. It's just an average of several shots. BB guns usually don't travel any faster than 450 FPS. Pellet rifles can travel up to and over 1200 FPS.

Caliber: . 175 & .177 Caliber This is the normal size for a BB and regular pellet. Pellets also come in .20 .22 & .25 Caliber. But the last 3 require a larger barrel to accommodate the pellet. BB are never this size.

There are three different power plants in Air guns:

C02: This is a gas that is used to propel the pellet or BB. Usually not faster than 400 FPS.

Spring & Piston: The spring in the pellet gun drives a piston to fire the BB or Pellet. There are commonly call Break Barrel rifles or Cocking rifles. They are usually single shot rifles because you have to re-cock them each time you want to fire. Some systems use a nitrogen gas in place of a spring but it works about the same.

Pump: In these pistols or rifles you have to use the forearm to pump up the air chamber to fire the pellet or BB.

There is one more type of system it called PCP ( I won't go into it here because it's expensive) Simply it requires a Scuba tank to charge the Air rifle. These rifles are high end rifles for hunting and Olympic class shooting.

So there you have it. Be Safe, It's a weapon not a toy.
