Guren 03-1 AEG Inner Barrel - 6.03MM - 420MM

Guren barrels are made of precise carbon steel & processed with HV500 coating.
This plating reinforced the hardness of the surface. It’s better than stainless steel (from HV200 to 400).

Guren barrels have a single cut groove for AEG chambers and a crown cut at the end of the barrel.

You can use this barrel with R-hop patches/bucking, the barrel cuts are squared to be 90 degree on the bottom. The window edges are cut at 45 degree to be gentle on the bucking.

Hop window length : 6.5mm
Inner Diameter: 6.03mm
Outer Diameter:  8.55mm
