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.

Easy-to-install barrel without snap ring
Snap rings are essential parts that determine various positions when setting up the stock, but they are prone to break when removing or assembling, and we felt that this made them difficult to work with.Our barrel has an outer diameter of 8.55mm, so by stripping the hop section to 8mm, a natural stopper is created, resulting in an inner barrel that does not require a snap ring.

The positional relationship after assembly is also firmly determined.

*There is a groove on the outer circumference similar to the genuine one, but this is a step to counter the nose R of the lathe's outer diameter bit tip.
Please be careful not to make a mistake as the groove width and depth are not compatible with genuine snap rings.

Tough barrel with an outer diameter of 8.55 mm that is resistant to vibration
While the original CA870 barrel has an outer diameter of 8mm, this barrel has an outer diameter of 8.55mm.
The original inner barrel guide cannot be used, so it must be removed.
da Vinci barrel guide We recommend using
It is possible to shoot by simply removing the stock guide, but since the chamber only includes the inner barrel, the barrel will be facing forward.
Please use the da VInci barrel guide to center the inner barrel.
*Not included with this product, please purchase separately.

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.
