AEG Ribbed Cylinder – Ported (200–400 mm)

AirsoftParts Stainless Steel Ported Cylinder – Gen 1.2
The port in the cylinder wall shortens the effective compression portion of the piston stroke, adapting the usable air volume to shorter inner barrels. Correctly matching the cylinder volume to the length and inner diameter of the barrel is important for efficient operation of the air seal system. The cylinder is made from stainless steel, has an inner diameter of 23.95 mm and a smooth inner surface for smooth movement of the piston head sealing O-ring. Gen 1.2 features revised dimensions for better compatibility and a smoother inner surface compared with the previous version. The manufacturer also specifies concentric machining, a ground surface finish and cooling grooves around the outer circumference. The cylinder weighs 31.3 g, is designed for V2 and V3 gearboxes, and the maximum recommended spring is M170.
