Power source | Mechanism | Muzzle velocity |
|---|---|---|
Mechanical piston | ||
Spring piston | Spring loaded piston | 1200 ft/s (370 m/s) |
Gas ram | pressurized air/nitrogen built into the piston | Â |
Pneumatic | ||
Multi/Single stroke | require pre-compression of air into the chamber using an on board lever | 700 to 1000 ft/s |
Pre-charged pneumatic (PCP) | Filled by decanting air from a reservoir to pre-compress air into the chamber | Â |
CO2 | ||
CO2 | require a disposable pre-filled cylinder of CO2 | 400 to 600 ft/s |
