MAO PAX-22

The PAX-22 is a CO2-powered dart rifle manufactured by Military Arms of Ostrava in the Czech Republic. The PAX-22 is nearly silent, and its darts can be loaded with any injectable poison, most often tranquilizer drugs used to bring down dangerous animals without causing any lasting harm.

The PAX-22's CO2 cartridge contains enough pressurized gas to fire 40 darts before needing to be replaced ($20, 0.25 lb.).
