[da Vinci Custom] 01 Raizen Gas Blowback Compatible Inner Barrel

*Please note that this item is made to order and will take approximately 1-2 weeks to be shipped after your order is placed.

Raizen 01 Inner Barrel
(Please choose the type and length from the variations)
Inner diameter 6.01mm
Outer diameter 8.55mm
SUS304

GBB/V10 SHORT compatible 70mm
It is about 4mm shorter than the original, and once installed, the barrel does not extend beyond the rifling position inside the outer barrel.
Output is reduced by approximately 10% compared to the original length.

GBB/GLOCK26 compatible 73.2mm
The inner barrel is designed specifically for the GLOCK26.

GBB/V10 compatible 74mm
Since it is the same size as the original, the inner barrel will reach the rifling position inside the outer barrel after installation.

GBB/GLOCK19 compatible 87mm
90mm compatible with GBB/M&P 9 and PX4
GBB/HI-CAPA4.3 compatible 95mm
Compatible with GBB/GLOCK17 and SIG P226, 97mm
GBB/XDM compatible 99.2mm

GBB/HK45 compatible 100mm
The inner barrel shape is exclusive to the HK45.

GBB/GLOCK34 compatible 102mm
GBB/M&P 9 LONG compatible 107.4mm
GBB/HI-CAPA5.1 compatible 112.5mm
GBB/FNX-45 compatible 113.4mm
GBB/M9A1 compatible 115mm
GBB/GLOCK34 LONG compatible 118mm

AAP-01 compatible 129mm
*The inner barrel for ACTION ARMY's AAP-01 has a groove at the tip for an O-ring.

GBB/FNX-45 LONG compatible 213.4mm
When a Marui tactical silencer is attached, it extends up to 22.9 mm from the tip.
Output is improved by about 10% compared to the original length.

The industry's highest quality SUS304 barrel, the "Raizen" series
Raizen barrels are made from the ultra-precision material "SUS304," which is manufactured 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.

Ultra-tight setting "6.01mm" for excellent initial velocity
The basic concept is that the smaller the clearance between the inner diameter and the bullet, the greater the pressure from the rear, and the higher the muzzle velocity (the faster the bullet flies).
The 6.01mm inner diameter is calculated to maximize the clearance for 6mm BB bullets, allowing for maximum pressure. However, due to the ultra-tight setting, it is designed for precision bullets. There is a possibility of jamming with inferior bullets.

Special tapered processing for improved performance
The muzzle has been tapered, just like the Guren 2. The tapered design allows air to be efficiently expelled, converting it into energy that pushes the bullet forward, while creating a straightened airflow and improving accuracy.

Raizen tapered processing

We have devised a special design for gas blowback barrels to accommodate a wide variety of variations.
It has a 45-degree chamfered edge, making it gentle on the hop packing.

*The inner barrel for ACTION ARMY's AAP-01 has a groove at the tip for an O-ring.

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.
