Crosman CM9B Mako CO₂ Pistol, cal. 4.5 mm (.177)

The Crosman CM9B Mako is a Beretta-style CO₂ semi-automatic BB pistol in .177 (4.5 mm) caliber, powered by a single 12 g CO₂ cartridge and feeding from a removable ~20-round magazine; it features blowback action for a lifelike recoil impulse, steel smoothbore barrel with a metal slide, fiber-optic front and rear sights, a Picatinny accessory rail and advertised muzzle velocities up to roughly 400–425 fps depending on BB type — a practical, value-oriented choice for plinking, training and fun range sessions.
