They are usually composed of plastic, but they are also available with a biodegradable compound. Plastic BB’s are often used indoors as for the Biodegradable BB’s are used for outdoors. A good quality BB is perfectly round, smooth and consistent throughout each batch. Typically a brightly coloured BB is easier to trace than your typical airsoft BB’s.

Up to 350FPS – 0.20g
Between 350 and 450FPS – 0.25 to 0.28g
Above 450FPS – 0.36 to 0.43g
