PDI Type 0 Full Bore Cylinder – Ver.2 & Ver.3 Gearbox Compatible (AK, M4, SIG 550 Series)

Japanese-made stainless steel full-bore cylinder designed for maximum air volume and FPS stability in Ver.2 and Ver.3 AEG platforms.

The PDI Type 0 Full Bore Cylinder is a high-precision, Japanese-manufactured upgrade component engineered to deliver maximum air volume and consistent compression in AEG builds. Constructed from polished stainless steel for reduced friction and long-term durability, this cylinder provides ideal airflow for longer inner barrels and high-performance setups requiring full air volume.

Designed for Ver.2 and Ver.3 gearbox platforms, the Type 0 cylinder is a trusted choice for improving FPS stability, enhancing shot-to-shot consistency, and supporting tuned hop-up systems such as R-Hop and VR-Hop.
