Both a springer and a gas ram utilize a piston in a cylinder and this sealed piston is forced down the cylinder, when the trigger is pulled, which generates a large volume of compressed air. This compressed air is then forced against the pellet which sends the pellet down the bore. The springer uses a long spring that is compressed when cocking and the gas ram uses some type of gas like nitrogen which is highly compressed when cocking the rifle, the gas ram uses two pistons, one to compress the gas and one for the compressed air to fire the pellet. Both the compressed spring & gas are what provides the force released by the trigger to power the piston and fire the pellet down the bore.
Thanks for the help as I am just trying to understand both concepts.
