Green gas and Co2 are two of the most popular energy sources for powering airsoft replicas.
Naturally, for those who play with a Gas or Co2 replica, it is essential to get a decent stock of Green Gas or Co2. Green gas or more commonly called Airsoft Gas is cheaper, generally sold in cans that allow a range of several hundred pellets. Co2 is sold in capsules weighing 12g to be applied to the replica. Easy to transport and replace, they allow a good range before being replaced.
