A pneumatic rifle and hand gun for discharging a projectile under the influence of a source of compressed gas such as air. The pressurization of the source is achieved by with pressure increasing mechanisms which compress atmospheric air in two separate stages using a single cocking or pumping action of the rifle or hand gun. The rifle and hand gun are provided with a recoil compensation device to eliminate recoil of the rifle and hand gun during discharge of the projectile. The compression of the atmospheric air to provide the source of high pressure is achieved through a novel piston and cylinder arrangement which pressurizes the gas during pumping or cocking action of the rifle or hand gun. A further mechanism provides for a projectile discharged from the rifle or hand gun to be subjected to constant pressure during discharge thereof. |
