What is Airsoft BBs?
Airsoft pellets (often referred to as “BB’s”, short for “ball bearing” or “big ball” in reference to smaller shotgun shot) are typically made of plastic and are almost always 6mm spheres. Pellets of a given size come in different weights ranging from 0.12 to 0.43 g. In addition to standard plastic pellets, starch-based biodegradable, metal coated, graphite coated (often used by snipers), and steel pellets are also available.
