AEG Ribbed Cylinder – Full (400 plus mm)

AirsoftParts Stainless Steel Cylinder Gen 1.2
The full non-ported design provides the maximum usable cylinder air volume, which is particularly important when correctly matching the cylinder volume to a longer inner barrel. The cylinder is made of stainless steel, has an inner diameter of 23.95 mm and a smooth inner surface for smooth movement and proper operation 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 for improved heat dissipation at high RoF. The cylinder weighs 32.6 g, is designed for V2 / V3 gearboxes and other compatible gearboxes. The maximum recommended spring is M170.
