[G.A.W.] FRUS O-ring for Tokyo Marui E-Bolt

This is a FRUS ultra-low friction O-ring for Tokyo Marui E-Volts.
It is compatible with E-Volt cylinders with an inner diameter of Φ18mm.

Made from a specially treated material, it has a dynamic coefficient of friction less than one-third that of conventional fluorocarbon O-rings (4D) and one-fifth that of nitrile rubber, and possesses special non-stick properties against almost all metals.
Unlike surface treatments, the entire material has been modified, so the effect will not be lost due to wear.

It also features a wide range of chemical resistance, making it compatible with all oils and greases.
It is effective for stabilizing muzzle velocity and increasing piston speed.
Depending on your setup, it can even be operated without oil.

Due to its extremely low frictional resistance, there is a possibility that muzzle velocity will increase significantly.
In such cases, please ensure you do not exceed the muzzle energy limits stipulated by the Firearm and Sword Possession Control Law by removing spacers from the spring guide or replacing the spring with a weaker one.
