Crosman introduced pump air-rifles -- designed for target shooting and small-game hunting -- in the early 1920s. The company's products include high-velocity pump and CO2 powered air guns that fire pellets and BB ammunition. The Crosman Auto Air II is a CO2 air-pistol designed to fire .177-caliber BB's. The design of the Auto Air II BB-pistol allows fast reloads that maximize the CO2 power.
