Description
Guren is made of precise carbon steel & process the HV500 Coat for the surface.
This plating reinforced a hardness of the surface so achieve around HV500.
It’s better than stainless steel (from HV200 to 400)
It’ll be kept clean & beauty surface for long time.
Of course, it’s good for anti rust.
Guren 2 is the best design for AIR SHOTGUN chamber & has a tapered muzzle end.
The tapered muzzle makes better accuracy & FPS but become happen a lots metal chips.
So be difficult for making continuously.
But we try to keep the best price with making good Airflow.
Dia. : 6.03mm
Outer Dia. : 8.55mm
About SAIGA-12K SBS
TM original inner barrel / Average 64.02m/sec (0.2g BB)
03 GUREN 2 – 200mm inner barrel / Max 72.59 , Min 63.91 m/sec
With the standard inner barrel, it fits entirely inside the outer barrel, but the 200mm da Vinci custom barrel protrudes slightly.
However, this can be completely concealed by using a flash hider.
The reason for extending it is that, in cases where the inner barrel is fully contained within the outer barrel like the standard version, the projectile is released without any guide.
To minimize this free distance as much as possible, we have maximized the length of the inner barrel.
About 400MM (SAIGA-12K EX)
Extend the inner barrel up to approximately 30mm from the muzzle tip.
SAIGA-12K FPS COMPARISON(300mm & 400mm)
Here are the actual measured values using 0.2g BBs with an uncustomized Tokyo Marui SAIGA-12K in an environment of approximately 23 degrees Celsius.
TM original inner barrel / Max 66.29 , Min 52.23 m/sec
03 GUREN 2 – 300mm inner barrel / Max 70.36 , Min 59.19 m/sec
03 GUREN 2 – 400mm inner barrel / Max 72.62 , Min 55.3 m/sec
At first glance, the 400mm inner barrel seems to deliver the highest values, but I feel that the 300mm inner barrel offers more stability. Likely, with an uncustomized setup, the 400mm inner barrel length may be slightly too long or close to the limit relative to the cylinder volume. Especially in Japan’s cold and humid conditions, this effect might become more noticeable. I am optimistic, however, that with customizations to fully leverage the 400mm length, it could potentially outperform the 300mm.
When our company publishes data, we want to ensure there is no misunderstanding:
we believe that “champion data” achievable only by professional users is not meaningful.
The above test values are from a completely uncustomized state, with only the inner barrel swapped out.
Please consider these numbers as a baseline, with the potential to be enhanced by your custom tuning skills.
Please fun with SAIGA & GUREN inner barrel !
