How PCP air rifles work?

Answer 1

PCP ( PerCharged Pneumatic) airguns and rifles work very similar to a C02 gun. The major difference is the driving force. A C02 rifle produced several hundred pounds of pressure that drives the pellet, the normal C02 cylinder is small. The PCP rifle uses C02 or Air and is built with a large high pressure chamber inside the rifle, sometimes it's a large bottle. This chamber is charged to between 2000 and 3000 PSI with a pump or Scuba tank. This extreme pressure fires the pellet at a very high velocity and because of the extreme pressure it can fire larger pellets than a normal .177 air rifle. Some PCP's models can fire a 50 Caliber pellet and bring down a deer or moose. In truth this class of air rifles (PCP's) are the same as real rifles
