Introducing the low-priced inner barrel series, Guren! It features a tight design with an inner diameter of 6.03mm, and is coated with the "HV500 Coat" which is highly resistant to wear and dirt, while maintaining a beautiful surface!
The Guren "1" was developed with the aim of releasing a barrel at the lowest possible price.
Because we cannot compromise on materials and coatings, we limit the processing methods and areas used to achieve low costs. All muzzle ends are chamfered to ensure a barrel that does not clog. This process shortens processing time and reduces the amount of metal waste generated during processing, lowering the product's reject rate and allowing us to set lower prices.

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.

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

We have devised a special design for gas blowback barrels to accommodate a wide variety of variations.
The edges are chamfered at 45 degrees 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.
