Rick, they can be powered by CO2, green gas or spring air like a Red Ryder. The spring air can be manual or elecrically driven and the automatic electrics can fire in excess of 20 BBs per second. Most good ones are 350 to 450 fps with a .20 g BB but some sniper rifles are considerably faster and have rules on how close you can be when you fire on someone.

By law they have to have .25" of orange on the tip of the barrel unless at a designated arena.

I can tell you that a .20g bb at 400fps will draw blood on a forehead at over 30'. I know because I was clearing a barn with my sidearm and he popped his head out of cover and I fired when I saw movement. He should have had his balaclava on.

I also use the pistol to dispatch mice in our detached garage.
