Original ported brass cylinder from Tokyo Marui.
An excellent budget upgrade if you need to change the cylinder volume or currently have an aluminium one installed.
Tokyo Marui Original AEG Cylinder
This cylinder features a port at the back as shown.
We recommend pairing this cylinder with a barrel no longer than 400mm & 6.05 ID with 0.2g ammo (shorter with heavier ammo).
Compatible with virtually all standard AEG gearboxes except TM spec M14s.
We recommend pairing this cylinder with a plastic piston head and lubricating it with liquid silicone oil.
