15 Raizen – AEG Inner Barrel

Description

Raizen is made of precise stainless steel which was the finest quality in Japan.
We’ve used this material for 20 years to create the best barrel.

Also about the design, it’s the best for AEG chamber & has a tapered muzzle end like Guren 2.
The tapered muzzle makes better accuracy & FPS.

Dia. : 6.01mm
Outer Dia. :  8.55mm
HOP window length 6mm

An adjustable, loose setting of ‘6.15mm’ is used for ease of tuning.
The basic concept is that the smaller the clearance between the inner diameter and the bullet, the higher the pressure from the rear, leading to an increase in muzzle velocity (the bullet flies faster). With an inner diameter of 6.15mm, there is a large clearance between the 6mm BB bullet and the inner wall. Depending on the settings, this can be used to aim for deceleration, or, in cases where a unit capable of overcoming sufficient air volume is installed, it can produce long-distance shots without stressing the bullet, offering an interesting aspect not found in tight barrels.

Soft fit for HOP rubber
The upper side , cut 45 degree to be soft for rubber.
Of course,you can use for Tokyo Marui AEG.

The chamfer size in the drawing is the target value.
The chamfer size may vary due to tool wear or material outer diameter tolerance.
Additionally, the chamfered area may become rounded during polishing.

HOP rubber is mold injection, So it may happen small round for the edge inside.
Then you can’t push the barrel to the correct position so Raizen made a bit bigger chamfer there.
So you can push the barrel to original position completely.

Easy fit to the chamber cause outer DIA. is 8.55mm around. You can put it by C clip parts.

What’s the difference between Raizen & R-code barrel ?
R-code barrel was designed to R-HOP unit.
Raizen is based on Marui original rubber,
