The cylinder holds the air that your AEG's piston compresses to fire each BB. Matching the cylinder's volume to your inner barrel length gives the best efficiency and consistency.
Choose non-ported and ported AEG cylinders from ZCI, Rocket and Prometheus, plus Silverback MDRX cylinders.

Ported or Non-Ported?
Ported cylinders have a hole that reduces the air volume, which suits shorter inner barrels. Non-ported cylinders deliver the full volume, suiting longer barrels. As a rough guide, longer barrels need more air, so less porting.
Our Cylinders
Choose the ZCI non-ported Type 0, ZCI 3/4 ported Type 2 or Rocket 5/6 ported cylinder. Prometheus stainless hard cylinders come in Type C and Type D. MDRX owners can fit the 100% cylinder or 75% stock cylinder.
