this is when compressed air is produced. With an opening available, certain

amount of air actually escapes out of the cylinder. The closer the opening

towards the cylinder head, the easier it is for air to escape. Shorter barrel

requires less compressed air to move the bullets away; therefore it does not hurt

to have a cylinder opening closer to the cylinder head. Longer barrel needs

greater power to kick out the bullets; therefore it cannot afford severe air

leakage. Of course, with a bigger mass of air remaining inside the cylinder

(waiting for compression), the workload will be higher for the system (meaning

possible tradeoffs between FPS, ROF and power consumption).

Recommendation: with a very long barrel

(450mm+-), you want a cylinder with no

opening at all. With a medium length barrel

(350mm+-), an opening located further

apart from the cylinder head is

recommended. With a short barrel

(250mm+-, like those in use by the MP5),

an opening slightly closer to the middle of

the cylinder is sufficient. With a very short

barrel (150mm+-, like those in use by the

MP5K and the G3 SAS), an opening in the

middle of the cylinder is good enough.
