Power Sources Covered in this review: CO2 - Spring Piston - Variable Pump -HPA (High Pressure Air)

Pro’s:

• CO2 Airguns allow for fast repeat shooting, great for action shooters, generally CO2 Airguns will supply a medium power range. No need to pump or cock your CO2 powered weapon in-between shots and a CO2 power source can allow for a very realistic action of the gun you are shooting.

• Spring Piston Airguns are best suited of single shot situations, they can provide low to high power output depending on the spring used. Spring Piston Airguns are very low cost to operate since you only need to buy the Pellets or BB’s. Spring Piston Airguns are not greatly effected by outside temperatures.

• Variable Pump Airguns allow you to decide how much power your gun will have and can offer very high power output depending on the Airgun. Variable Pump Airguns are very low cost to operate since you only need to buy the Pellets or BB’s. Variable Pump Airguns are not greatly effected by outside temperatures. Variable Pump Airguns generally have very low recoil and vibration.

• HPA (High Pressure Air) Airguns generally do not require pumping or cocking in-between shots and some even come in semi automatic or bolt action. HPA Airguns can have very high power output and even be used on larger game using large caliber ammunition. HPA Air Rifles have lower recoil and low vibration. HPA Airguns can be charged ahead off time so they are ready for use when you need them.

Con’s:

• CO2 Airguns require the additional cost to buy the CO2 as they do not function without it. CO2 Airguns have a limited power output and lose power as you shoot and use up the CO2. CO2 Airguns are effected by hot and cold temperatures and will have less power in colder temperatures and may not even work in super cold environments.

• Spring Piston Airguns require cocking before each shot. Spring Piston Airguns can have a lot of recoil and vibration, so much so that special optics must be considered when buying an optical sight. The action of the spring recoil can effect accuracy, especially if you are not use to the vibration and recoil or have spent some time practicing using a Spring Piston Airgun.

• Variable Pump Airguns will require multiple pumps to achieved maximum power output which can take some time in-between shots. So you are going to have to work for each shot.

• HPA (High Pressure Air) Airguns require the use of a manual pump to fill their built in air tank to maximum pressure and it does take a lot of time to manual fill an HPA tank. Alternatively you can have the air tank filled at a shop or buy a pressurization system similar to a scuba tank out paintball setup, the cost of this setup can be very high but will save you the castle of manually pumping air in to your HPA Airgun. HPA Airguns are generally a little more bulky then other Airgun systems since they have to accommodate fairly large air pressure tanks.
