Pre-Charged Pneumatic Rifles(PCP) This is the group of rifles that has advanced the most in the last 10 years. They use a reservoir built into the gun to hold a store of compressed air, usually about 2500-3000PSI. This reservoir can hold anything from 30-500 shots worth of air depending on the size of the cylinder. The compressed air cylinder is charged via a hand pump or divers bottle. The regular spray compressor, garage pump or foot pump will NOT do the job as they do not run at high enough pressure.
