Miyagawa Rubber [Made in Japan] MIYA-BON V2 Long Sock (Pack of 2) Chamber Gasket for Marui Gas Guns/Gas Blowbacks, Patent No. 693145

Nitrile 60° (black) for assault rifles (gas) with rubber insert
Silicone 50° (red) for handguns (gas) + Push-in rubber included

In order to stabilize the accuracy of gas blowback handguns that use freon gas, the performance of which is easily affected by temperature and remaining gas,
Two rail-like protrusions are provided.
This structure makes it possible to maintain a constant position for bullets that tend to jump sideways.

New feed port and long rail feed port. The new gas pro bucket has a cut-out at the feed port to provide cushioning and prevent backflow of air. This virtually eliminates nozzle sticking and air loss.
- Prevents the nozzle from getting caught, allowing for smoother bullet feeding.
- The crease makes it less likely for air to leak out.
Long Rail A notch has been added to the entrance of the long rail to hold the bullet more stably.

■Compatible models: This is a common backing for various Tokyo Marui gas guns (with some exceptions) and the VSR-10 series.
HI-CAPA4.3/5.1 M1911A1 MEU
P226 (and E2) GLOCK 17/18/19/26/26ADV
SOCOMMK23 HK45 (and Tactical) VSR-10 (and G-Speck)
Gas Blowback MP7A1/M4A1 MWS M40A5 USP M45A1

■Regarding protrusions: The crest-like protrusions found on genuine Marui gaskets are not present on Miyagawa Rubber gaskets.
Originally, it was thought that this was attached to prevent the packing itself from rotating, but if this protrusion fixes the shaft, it becomes impossible to correct any misalignment when centering the packing protrusion (the process of aligning the protrusion with the center of the barrel).Even without the protrusion, there is no problem with the product, and it is possible to make fine adjustments when centering.

*The hop arm may not engage properly depending on the gun model or when using heavy bullets. In this case, please bend the hop arm before use.

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.
