The MadBull Black Python Ver.II precision inner barrel features a 6.03 mm inner diameter and a 509 mm length, designed for electric airsoft guns (AEGs). It enhances shooting accuracy and shot-to-shot consistency by providing a precisely machined bore and a high-quality internal finish, allowing the BB to travel more smoothly and consistently for tighter groupings.
This model is compatible with airsoft replicas that use a 509 mm inner barrel, including M16A1, M16A2, M16 VN, Steyr AUG, and other AEG platforms with the same barrel length.
This version features a gold finish, making it visually different from later Black Python models that were released with a darker exterior finish.
For optimal performance, the use of high-quality precision airsoft BBs is recommended.
