The second release in the Guren series, a low-priced inner barrel series featuring a tight 6.03mm inner diameter and HV500 coating that is highly resistant to wear and dirt while maintaining a beautiful surface!
Guren "2" aims to produce a professional-use barrel using iron.
The material and coating used is the same "HV500 Coat" as the Guren 1.
The muzzle has been upgraded from the "chamfered" finish of the Guren 1 to a "tapered" finish. The "tapered" finish efficiently expels air and converts it into energy that pushes the bullet forward, while creating a straightened airflow and improving accuracy.

The 6.03mm inner diameter is a tight barrel design that makes it easy to increase muzzle velocity. <br>The inner diameter is set to a tight 6.03mm, so you can expect to improve muzzle velocity just by replacing the barrel.
This product is made of iron. Unlike stainless steel, due to tolerances, the tightest design limit is an inner diameter of 6.03 mm.
If you set it any tighter, it will jam.

We have devised a special design for gas blowback barrels to accommodate a wide variety of variations.
A 45-degree chamfer has been added to prevent damage to the hop packing.

Guren's inspection standards include three internal diameter inspection points: "after polishing," "before coating," and "after coating."
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.
We put in time and effort to provide a thorough user experience.
Regarding roughness of the inner and outer diameters due to the material, and patterns that occur during processing (cutter marks, blade marks, etc.) that do not affect use,
After going through the above checks, the craftsman has given his permission, so please use it with confidence.
