After installing the product, please use it in accordance with the law.

■Notes■
Things to keep in mind when incorporating parallel

Miyagawa Rubber's chamber packing has an outer diameter 0.1 mm thicker than the original to improve airtightness. This can make it difficult to install into the barrel.

Do not use petroleum-based lubricants such as Kre556 . Instead, use a small amount of diluted neutral detergent.
- In the case of nitrile rubber, silicone oil can also be used.
- Silicone gaskets are not recommended as they will expand even with silicone oil.
- Fluorine oil can be used with all rubber types.

※please note※
If you have customized your airsoft gun or replaced parts, be sure to measure the bullet speed using a bullet speed meter to ensure it is within the legal limit (possession of bullets over 0.98 J is prohibited). Also, be careful not to exceed the legal limit during the work.
