Since air rifles do not rely on gas produced by the burning of a powder, the shorter barrel does not lower muzzle velocity. This is important in an air rifle since the pellet travels much slower than the bullet in a typical firearm. The C60's power system consists of an interchangeable 73 gram CO2 cylinder that screws into a slot in the forearm under the barrel. CO2 tank and adapter. Lacking a freezer, the cylinder may be cooled by partially filling it and bleeding off some of the CO2 with the supplied bleed valve.
Maximum fill is determined by weighing the cylinder.
A special valving system provides consistent velocity at any ambient temperature. The cylinder may be removed from the rifle in any state of charge. Pellets are loaded by thumbing the charge lever in front of the loading gate, which raises the loading gate and exposes the bore, and inserting the pellet directly into the bore. There is enough room to use a pellet seating tool, if desired. During the loading process, a gate pops up and obscures the rear sight and the trigger is locked, effectively preventing discharge while out of battery.
