The industry's highest quality SUS304 barrel, the "Raizen" series
The Raizen barrel is made from the ultra-precision material "SUS304" produced using Japan's proud semi-conductor manufacturing technology.
Our unique surface roughness setting with a tolerance of ±0.005mm was achieved through collaboration with a company headquartered in Tokyo.
For machining, we use Star Micronics multi-tasking machines - 8 axes (X, Y, Z1, A, B, C, E, Z2) - and use the optimal tools to cut and reproduce the drawings down to the smallest detail. For the finishing polishing, we use machines and craftsmen in a system that does not allow for any compromise, resulting in a quality that cannot be imitated by other companies.

6.05mm: A good balance of distance and accuracy
The 6.05mm inner diameter is narrower than that of 6mm BB bullets, but it is not too tight, so it receives air pressure from behind while reducing the number of times the bullet hits the inner wall, resulting in an excellent balance between long flight distance and high accuracy.
It is resistant to scratches and stains that are unique to stainless steel, and maintains a beautiful surface for a long time, ensuring consistent output.

Special tapered processing for improved performance <br>The muzzle has been tapered, just like the Guren 2. The tapered processing efficiently expels air and converts it into energy that pushes the bullet out, while also creating a straightened airflow and improving accuracy.

"Explanation of Electric Gun Barrels"
A stopper has been added to accommodate not only AEG chambers but also M14 chambers.
The hop window is 6mm long and is designed to be larger than the original barrel.
Furthermore, the hop packing coming down from above is designed with a 45-degree chamfer to prevent damage to the packing.

*Toy guns are made up of many parts. Depending on the combination of parts, performance may not be achieved.

Designed with Hop Packing in mind
Marui gaskets are molded from nitrile rubber.
We believe that gaskets from other manufacturers are generally molded products.
Unlike cutting, the precision of rubber molding is often in the 0.1mm range, and it is difficult to create right angles on the inner end surface of the rubber.
There may be some R. Even in this case, the chamfer on the barrel's outer diameter is made slightly larger so that the barrel can be pushed all the way in.

The outer diameter is 8.55mm (negative) to allow for compatibility with various chambers. <br>The outer diameter is made to be 8.55mm (negative), to allow for use with not only the original chamber but also various other chambers.
If the diameter is too thick, it will adhere better to the chamber packing, but it will have the disadvantage of being difficult to insert into the chamber or not going in straight. By making the outer diameter 8.55mm, we have created a barrel that is easy to set up.

*Due to the specified tolerance, there may be cases where the diameter exceeds 8.55mm, but this does not mean that the part will not fit into the chamber.

At Raizen, we have established an internal diameter inspection point "after polishing" as an inspection standard .
In particular, we physically check to see if any burrs generated during processing have affected the inner diameter.
The polishing is then checked again by the "human eye" of a select few craftsmen in charge of polishing.
Up to this point, the items are the same as those for Guren, but the surface roughness pass criteria are one level stricter, and roughness that occurs in the material is strictly selected.
The reason why Raizen is a high-end barrel is not only the cost of the materials, but also the time it takes to select them and the amount of rejected material.
Therefore, the bottle you receive will be a carefully selected item.

Regarding patterns (cutter marks, blade marks, etc.) that occur during processing and do not affect use,
After going through the above checks, the craftsman has given his permission, so please use it with confidence.
