About Our Airsoft Cylinders

An integral piece of your AEG internal parts, get a fresh upgrade or replacement for your airsoft cylinder at Patrol Base. You can enjoy a vast stock to choose from, including AEP compatible cylinders, electric M4 rifle cylinders and more. 

The airsoft cylinder contains your piston, and is what holds the volume of air created by your piston operating. The cylinder and piston work together, using air to propel your BB out of your airsoft gun. 

There are different types of cylinders for different applications. There are ported and non ported cylinders - the main difference being that ported cylinders allow you to adjust barrel volume. Some cylinders also hold a larger volume of air than others. 

As a general rule, AEGs with a shorter barrel will want a cylinder that allows more air to escape and longer barrels will want a cylinder with a higher volume of air and less porting. However, as always this is really down to experience and personal preference.
