HOP packing for air cushion inner barrel.
This gasket was specially developed for VSR and Marui GBB.
Please use this packing when using the air cushion inner barrel for the Action Army AAP01 Assassin gas blowback.
There are three types of hardness: 50°, 60°, and 70°, and the color varies depending on the hardness.
As a guideline, Tokyo Marui's genuine hop-up gun packing is about the same size as the 50° gun. The 50° gun is suitable for 0.20g BBs, while the 60° and 70° guns are suitable for 0.25g or larger BBs. The harder the packing, the stronger the hop-up gun will be.
