[Miyakawa Rubber] [Made in Japan] MIYA-Long Hanging Double Hold / Fat Chamber Gasket (2 pieces) + Dedicated Push Rubber

A new product has been released in the Miyagawa Rubber Nagakake series. Similar to the standard surface hop-up system used in flow rate tuning, this increases the contact distance with the BB bullet, allowing for a stronger hop rotation. At the same time, by holding the gun at two points on the top, it reduces left and right wobble and dramatically improves accuracy.
In terms of durability, the system with semicircular protrusions that create long hooks has been significantly improved compared to the surface hop packing system, which creates protrusions only through the thickness of the packing body.
This long-hanging fat rod has a longer and thicker rail protrusion than the previous mid/slim rods, allowing it to hold BBs firmly, so even heavy bullets can be rotated firmly.
In addition, additional clogs have been added between the rails for reinforcement, making it durable enough to withstand customization such as high-speed cycling.
It also improves accuracy, is resistant to wear and highly durable, but hop adjustment becomes a little more difficult.

・Nitrile Hardness 50 + Dedicated Push Rubber
·silicon Hardness 60 + dedicated push rubber
・0.25g to 0.3g BB bullets are recommended.

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.
