This is a replacement 7.7mm machine gun barrel designed for the 1/48 Tamiya A6M Zero (Aircraft Series No.103 & No.108). The part features a detailed barrel jacket with properly modeled vent holes, offering a more realistic appearance compared to the solid kit part (A35). It is designed to directly replace the kit part without any modification. Please note that this barrel does not fit Tamiya Aircraft Series No.16, No.25, or No.27. The part is modeled with accurate proportions suitable for 1/48 scale. The part was test‑printed to verify general fit, but small adjustments may still be necessary depending on printer differences and kit tolerances.
